Adhesives & Adhesive-Bonding - now properly defined & described online on Wikipedia

Experts from the German Adhesives Industry have substantially revised the German-language Wikipedia entries on adhesives & adhesive-bonding. This project was initiated and co-ordinated by IVK - the German Adhesives Association.

Over the past 17 years, Wikipedia has become one of the world's most important online information services, with several million users accessing this free ecyclopedia every day - and with a significant upward trend.

In this context it is important for both, the users and the industry that the information provided by Wikipedia is content-wise and technically correct and therefore reliable.

In the past, this has not always been the case - at least with respect to the German-language Wikipedia entries on adhesives and adhesive-bonding.

Therefore, IVK-experts took the initiative to substantially revise the entries on adhesives & adhesive-bonding on the German version of Wikipedia - thus, now providing correct and reliable information.

IVK seea an urgent need to also revise the other language editions of Wikipedia with respect to the entries on adhesives & adhesive-bonding.

According to Ansgar van Halteren, CEO & Executive Board Member of IVK, there are considerable differences in the content and sometimes also serious & misleading errors in the definition and description of adhesives & adhesive-bonding in the various language editions Wikipedia, that urgently need to be harmonized.

National and European legislators are also increasingly using Wikipedia to obtain background information. However, it is an absurdity for different European parlimentarians to receive different information on the same topic in their respective mother tongues.

The European adhesives industry would be well adviesed to initiate the necessary harmonization process - ideally also globally - in a timely manner.


New European Standardization Project on Determination of excessive Humidity in Subfloors successfully launched

IVK-experts in the field of flooring & parquet-flooring adhesives have successfully launched a new European standardization project at CEN/TC 193 "Adhesives" which aims at to develop a test method for the determination of excessive humidity in subfloors.

The test method will allow an easy assessment of the dryness of any kind of subfloor prior to the installation of floor-coverings or parquet-floors bonded with adhesives. The method will be independent from the subfloors' chemical compositions or materials and applicable with commonly available equipment.

The excess of humidity in a subfloor os a very common problem in construction which may cause a saponification of the adhesive used for the instalation of floor-coverings - resulting in a weakening of the bond strengh, and it may trigger VOC emissions & bad odor.

The new developed test method will enable a floor-technician to determine the appropriate time for the application of an adhesive - thus, avoiding saponification, loss in bond strengh, VOC emissions, or disturbing odors. As this test method will be independent of the subfloor material it will not measure a subfloor characteristic, but a subfloor condition.

This project is another valuable contribution of the German Adhesives Industry - giving support to make bonding in the field of flooring & parquet-flooring installations even safer, and thus, avoiding costly complaints. German floor- & parquet-flooring installers welcome and fully support this initiative of the adhesives industry in terms of a confidence-building measure along the value chain.


Adhesives Industry in the Cost Trap

Significant price increases for basic chemicals and intermediates, limited availability and a strong global demand make adhesive raw materials significantly more expensive. In addition, steadily raising regulatory costs and the shortage of freight capacities are leading to noticeable additional burdens on the cost structure of German adhesive manufacturers. 

Düsseldorf - Since the beginnig of 2016, the adhesives industry has been concerned about significant price increases for basic chemicals and intermediates, which are the chemical basis for a large number of key adhesive raw materials.

The contract price for ethylene in Europe has risen by about 40% in the past 24 months, the price of propylene even by 70%. Butadiene, for which the price has almost doubled, and styrene (+ 30%) belong to the category of so-called "volatile commodities"; their price levels in Europe are strongly dependent on the global supply and demand structure.

Already since mid-2016, these additional costs for basic chemicals have had an impact on the prices for intermediates and specialty chemicals that have noticeably risen.

For Vinyl Acetate Monomer (VAM), the main raw material for aqueous dispersion adhesives, as well as for so-calles EVA polymers, the adhesives industry has seen price increases of 40% since the end of 2016. The reason for this is a strained, import-dependent supply situation due to a strong and continuing demand, especially from the Asian and US markets.

The landed costs for the typical raw materials for the production of thermoplastic hot-melt adhesives - EVA polymers, polyolefines, resins and waxes - have also increased significantly over the same period in line with the aforementioned cost development of raw materials.

The limited availability of polyesters and isocyanates has a drastic effect; they are the main components of polyurethane hot-melt adhesives. The price increases for isocyanates have been up to 70% over the past two years. Due to several Force Majeur declarations from various manufacturers in 2017, the availability in the world market is still limited and the adhesives industry is faced with significantly higher raw material costs. Due to the very high proportion of isocyanates in the formulation of PUR adhesives, the production costs of these products are particularly affected.

The continuing limited availability of raw materials, combined with an enduring strong global demand for basic chemicals and specialty chemicals from which adhesives are made, ultimately leads to further additional burdens on the formulation- and production cost structure of German adhesive manufacturers.

In addition, the entire chemicals industry, which includes the adhesives industry, is confronted with a multitude of national and European laws and regulations (Renewable Energy Sources Act, Federal Immission Control Act, REACh, CLP, EU-Biocide Regulation, etc.) which create significant administrative overheads throughout the value chain.

Another particular challenge at present is the scarcity of freight capacities in Europe, which is directly attributable to the growing shortage of qualified driving personnel, and which has made transport significantly more expensive.


Adhesive Applications designed for Recycling

European Paper Recycling Council moves forward  on eco-design of printed paper products

In March 2018 an update has been made to the European Paper Recycling Council's (EPRC) "Assessment of Printed Product Recyclability". This Scorecard for the Removability of Adhesive Applications now includes an annex for applications where there is sufficient experience and confidence that they will deliver good results on removability. Non-water-soluble or non-redispersible hot melt adhesives are now exempted from testing under certain conditions. If an adhesive application does not conform to with the conditions in this annex, no conclusion can be made about its removability.

The update of the scorecard is based on new scientific insights resulting from a joint research project which was initiated by experts from IVK in co-operation with INGEDE (International Association of the Deinking Industry) and the University of Darmstadt. In this project it was scientifically proven that the softening point, the thickness of application and the geometry of an adhesive seam of non-water-soluble / non-redispersible hot melt adhesives have a decisive influence on the removability of these adhesives in the paper recycling process.

IVK and EPCR consider this a step forward towards improving eco-design, prolonging the recycling loop for printed graphic paper.

The updated scorecard can be found here.


Ansgar van Halteren joins the Board of Trustees of IFAM

Ansgar van Halteren - CEO and IVK Executive Board Member - has recently been appointed as member of the Board of Trustees of the Fraunhofer Institute IFAM.

With 5 locations and more than 600 employees the Fraunhofer IFAM is one of the most important research institutions in the field of adhesive bonding technology, surfaces, shaping and functional materials in Europe. Scientific excellence, a clear focus on the application of technology, measurable utility for customers, and always ensuring the highest quality built the fundament of IFAM's strong position in the research market - and thus, the basis for future-forward developments, for the benefit of the society.

60 years old van Halteren started his professional career in the adhesives world back in 1983. He was appointed as IVK's Senior Executive in 1992 and Executive Board Member in 2002. Until to date, van Halteren signs responsible for the operations of the world's largest national adhesives organisation - actually representing 137 companies and a domestic industry turnover of more than 3.8 billion Euros/year.



Industry's Business Perspective has not been as optimistic since 2011

Despite economic and geo-political risks, a solid global economic upswing is emerging, and it is also perceptible in the German Adhesives Industry. The positive development is based on a good export situation, a good construction market as well as on an increasing demand & investments in mechanical engineering. A slight headwind derives from currency effects and challenges regarding the current raw-material availability.

The good economic conditions are also reflected in IVK's bi-annual Business Survey: the Business Barometer shows a positive picture of the current market- & business situation, and of the sales development; the industry's business perspective has not been as optimistic since 2011. This positive business-rating also applies to the expectations of IVKs membership with a view on the upcoming financial year.
The results of the business survey for the German and Dutch-speaking areas (A, CH & NL) show an even slightly better economic outlook in terms of market conditions and sales.

IVK welcomes Chinese Delegation from CPCIF & MIIT

In October 2017 a Chinese delegation - lead by high-ranking representatives of the China Petroleum and Chemical Industry Federation (CPCIF) and the Chinese Ministry of Industry and Information Technology (MIIT) - visited IVK's headquarter in Düsseldorf. During the course of an in-depth discussion the structure and the broad services-portfolio of IVK and the technological & economic importance of the German Adhesives Industry were presented. A special focus was given to the issues of Circular Economy & Sustainability and the valuable contribution of the adhesives bonding technology towards design, recyclability, re-workability & sustainability of bonded products.



NEW RELEASE: Adhesives Technology Compendium - Edition 2017

A brand new 2017 edition of the Adhesives Technology Compendium has been published this month.

In a joint project the German Adhesives Association (IVK) and the editors of the magazine ADHESION - Adhesives & Sealants started already back in 2009, to publish the Adhesives Technology Compendium every second year. Since 2015, the team of authors has been extended to IVK’s fellow associations from Austria (FCIO – Austrian Association of Flooring Adhesives), The Netherlands (VLK – Dutch Adhesives and Sealant Association) and Switzerland (FKS – Association of the Swiss Adhesive and Sealant Industry).

Thus, the newly published reference book 2017 contains the company profiles of more than 160 adhesive & sealant manufacturers, raw-material suppliers, dosing & mixing equipment suppliers, research institutes, as well as consultancy companies and toll manufacturers from these four European countries. Furthermore the compendium gives a survey on the broad activities and committee work of IVK and its sister associations, as well as on European legislation & regulations, statistics and standards, important to the European Adhesives & Sealants Industry.

The Adhesives Technology Compendium is an important element of the communication strategy of the German- & Dutch-speaking adhesive Industries. Therefore 5,500 copies of this reference book will be distributed throughout Europe, Asia and the US.

An e-paper version is also available on the internet:



Annual Press Conference 2017

On its annual press conference 2017 IVK reported that the German Adhesives Industry continues on an solid growth path and presented the corresponding facts & figures.

In the financial year 2016, the German adhesives industry generated revenues of 3.7 billion Euro with all adhesive systems combined, thus fulfilling the growth forecast of 1.2 percent nominally. The outlook for the economic growth is positive as well.  For the current financial year, industry observers forecast a nominal growth in turnover of at least 2.0 percent. A major growth engine contributing to this trend is the strong performing construction sector.

The economic data correlates with the results of the current IVK economic survey, where for the first time also Austrian, Swiss and Dutch adhesives manufacturers were polled.  Their assessment of the market situation has not been this positive since 2011.

The worldwide annual sales of adhesives and sealants, cement-based construction materials and adhesive tapes amount to almost 61 billion Euro. With a global market share of approximately 19 percent, the German adhesive industry is the world market leader. In Western Europe as well, this industry sector with adhesive consumption of 27 percent and an adhesive production share of 34 percent takes first place in both categories. Besides domestic sales of 2.1 billion Euro, Germany exports products worth almost 1.7 billion Euro. In addition, German adhesive manufacturers generate a turnover of 8.1 billion Euro locally in their overseas production plants.

In 2016, the most important types of product in terms of production volume were dispersion adhesives with an overall production volume of around 420,000 tons. Next in line were reactive adhesive systems with 250,000 tons and hot melt adhesives with 150,000 tons.

The main sales markets for adhesives are the sectors of paper/packaging, automotive industry, wood, electronics and construction industries.  In 2016, turnover increased in all other sectors – with the exception of the graphic arts industry.  In the wood and construction industry, sales increased by 1.2 and 2.6 percent respectively compared to the previous year. The sector of electrical and optical equipment with a growth rate of 1.1 percent in Germany has a major global significance for the adhesive industry. Here, adhesives are used to mount lenses and prisms in optical equipment.

For the current financial year, the German adhesives industry expects the positive economic dynamics to continue. "Despite a long list of risk factors, the global economy remains on a steady growth course. A similarly positive picture is seen in the user industries for adhesives", forecasts  Dr. Tasche, chairman of IVK. "We expect a nominal sales growth of at least 2.0 percent and approximately 3.8 billion Euro in total sales for the German industry sector". 

One challenge is the continuing increase in raw material prices. Overall, the supply situation for major basic raw materials is generally good, however for some intermediate products there are reports of Force Majeure. "Mainly for isocyanates and raw materials for polyurethane adhesives, shortages can be observed",  notes Dr. Tasche.



Adhesive Bonding Roadmap outlines Areas of R&D

IVK is intensively involved in an interdisciplinary platform (GAK - Joint Committee on Adhesive Bonding), which combines expert knowledge in the field of adhesive bonding technology from the adhesives industry, science, and customer industries.

Research in the field of adhesives / adhesives bonding is a key factor in the development of innovative products in many industries. However, there is still a need for extensive research in order to enable the use of adhesives in production processes to be managed more effectively and to enable the service life of bonded joints to be predicted more reliably. A roadmap which has been developed by experts from GAK outlines current and future areas of research in adhesive bonding technology an provides orientation for application-oriented R&D.

Adhesive Bonding Roadmap: Increasing Trust in Adhesives


IVK successfully launched 6 New Work items on ISO level

ISO - the International Standardisation Organisation has accepted 6 new work items (NWI) in the field of flooring-adhesives.

At a request of IVK - launched by DIN - the necessary majotity of six ISO members, namely SAC/China, AFNOR/France, UNI/Italy, JISC/Japan, and ANSI/USA, were in favour to transfer the European Standards:

  • EN 1372
    Adhesives - Test method for adhesives for floor and wall coverings - Peel test
  • EN 1373
    Adhesives - Test method for adhesives for floor and wall coverings - Shear test
  • EN 1903
    Adhesives - Test method for adhesives for plastic or rubber floor coverings or wall coverings - Determination of dimensional changes after accelerated ageing
  • EN 1841
    Adhesives - Test method for floor coverings and wall coverings - Determination of the dimensional changes of a linoleum floor covering in contact with an adhesive
  • EN 13415
    Test of adhesive for floor covering - Determination of the electrical resistance of adhesive films and composites
  • EN 14259
    Adhesives for floor coverings - Requirements for mechanical and electrical performance

into ISO-Standards. The six organisations confirmed their commitment to support these 6 NWI's, and to work actively on the projects. Surprisingly BSI/UK, FSF/Finland, and KSK/Korea did not support IVK's request.

A first expert discussion on the NWI's will take place at the meeting of ISO/TC 61/SC 11/WG 5 "Plastics/Products/Polymeric Adhesives" on September 19, 2017 in Korea; an expert from IVK will participate in this meeting.

According to the ISO-rules the new standards have to be finalized and published within 36 months; due to the fact that these NWI's are based on existing EN-standards which are broadly used by craftsmen & industry, the publication of the new ISO-standards is expected within the next 24 month.

IVK interprets this positive result as further evidence that its active participation in ISO standardization in the meantime bears fruit.


Adhesive industry continues to grow

The majority of the German-speaking and Dutch adhesives industry assesses the current business situation as good. Economc expectations for the second half of 2017 are also being positively assessed by the companies. This is a result of a business survey conducted by the German Adhesives Association.

The bi-annual economic survey conducted by IVK is an important indicator of the economic sentiment of the industry. In addition to adhesive companies from Germany, manufacturers from Austria, Switzerland and the Netherlands were also interviewed for the first time this year. A total of 100 companies participated in this representative IVK-survey.

Outlook for the year 2017

Expectations for the upcoming months are positive: 40 percent of companies expect a more favorable market situation. Increasing sales and a higher export volume are expected by 65 percent of German, Austrian, Swiss and Dutch adhesives manufacturers. According to almost two-thirds of respondents, the number of employees will remain constant. The remaining third expects an increasing number of employees. Overall, the German, Austrian, Swiss and Dutch adhesives manufacturers employ more than 16,000 people.

On the basis of this economic survey and key economic indicators, the economic year 2017 will show a moderate but robust economic dynamic, which is expected to result in a growth of at least 2 percent. In addition, there will be some positive export effects. The current tense raw material situation is a challenge for the adhesives industry.


Adhesives Companies are increasingly focusing on bio-renewal Adhesives

The share of bio-based adhesives on the market is growing. The German adhesives industry is driving this development and working on new formulas based on renewable raw materials. In doing so, nature is being used as a model. Already Leonardo da Vinci based his flying machines on the movements of birds. Today, numerous products are based on biomimetics. Well-known examples include Velcro, which researchers copied from the burrs of the brudock plant, or echolocation from bats, which is used in parking assistant systems.

Adhesives manufacturers are taking things a step further: they are not only adopting mechanical processes from nature but chemical ones as well. The aim is to establish bio-based adhesives as an equivalent replacement for mineral oil-based adhesive solutions.
Already today, 15 percent of the adhesives used are made from renewable raw materials. This figure will continue to rise in the years ahead.
One of the challenges lies in the technical implementation. Natural materials have much more complex chemical structures than mineral oil. That is why IVK member companies are conducting intensive research in this field. The development will increasingly result in a production process based in natural materials rather than on petrochemical raw materials.

The medical field has been using bio-based adhesives successfully for years. For example, doctors use a mussel-based adhesive as an effective method to close small tears in the amniotic sac. Advantage: the adhesive contains certain proteins which are particularly well-tolerated by the body. It also works within the space of 10 to 20 seconds and can be applied very precisely.


IVK position regarding the proposed EU-Ecodesign Requirements for electronic Displays

The German Ahesives Association has strong concerns about the proposed resource efficiency requirements draft EU-Ecodesign regulation for electronic displays and devices as well as similar provisions discussed for the product categories servers & storage devices and computers - only allowing the use of adhesive tapes!

Representing producers of key enabling technologies, IVK-members fear various negative impacts on their business, customers and innovation capacities along the whole value chain. IVK hence urges the European Commission to reconsider its draft and propose a solution that allows continuous innovation while at the same time preventing a technology lock-in in the near future.

Ahesives - applied as a liquid or as a tape - are on of the most important enabling technologies of today's state of the art technology in the electronics sector. They allow design for slimmer, smaller, lighter and better sealed products with electronic displays (e.g. laptop computers, tablets, medical devices, etc.) as well as servers, storage devices, and computers. Thereby, adhesive-systems contribute to several positive life-cycle benefits of singular devices. They enhance features such as resource efficiency through increased durability and lifespan of the product leading to less repairs and conservation of resources as well as convenience and safety on the side of the consumer.

Neither liquid applied adhesives nor tapes do prevent a product's recyclability. If recyclability is part of a customer's demand this requirement can be fulfilled when designing the adhesive bond.

Because of high investments in development of the respective solutions in recent years, today many adhesive bonds used in the products affected by this regulation are "re-workable". This means they "de-bond" through the application of heat and commonly available techniques to facilitate dismantling of the prouct's components.

To add, liquid adhesives are technically not different to duoble-sided adhesive tape, which would be allowed under the current Commission porposal. Double-sided adhesive tape is merely liquid adhesive coated and dried on an inert carrier, which might have benefits in application. However, it does not further simplify  dismantling, as the adhesive used for a tape can even have the same or higher strength than a special liquid adhesive. Consequently, the allowed technology would have a worse environmental impact than the prohibited one, thus contradicting Circular Economy goals.

If the regulation were to be implemented as currently proposed, the competitiveness of the adhesives industry and the whole electronics sector would be severely impacted. In addition, imposing specific technologies to manufacturers will potentially result in a technology lock-in, thus hampering innovation and preventing the development of more efficient products in the future. This also goes against DG Energy's commitment to innovation and its endorsement of the Innovation Principle.


EU Council decides not to nominate Silicone base-material D4 under the Stockholm Convention

EU commission intended to classify octamethylcyclotetrasiloxane (D4) as a Persistent Organic Pollutant (POP) according to the Stockholm Convention, which would have resulted in a ban on D4.

D4 is an essential raw material for the production of silicones, and thus, a key raw material for the production of silicone-based adhesives and sealants.

Co-ordinated by FEICA, European and national authorities have been specifically addressed and urget to vote against the EU commission proposal to list D4 as a POP under the Stockholm Convention. In Germany, IVK has contacted all relevant ministries and related agencies, accordingly.

This European initiative was a complete success!

At its meeting on April 12, 2017 the European Council voted against the proposal of the Eu Comission to submit D4 as a POP under the Stockholm Convention. Thus, a general ban on D4 is no longer possible!

As demanded by the industry, a procedure under REACH will now specifically examine for which applications D4 should be excluded, focusing on rinse-off-applications where D4-particles could enter wastewater - e.g. cosmetics, body care products, cleaning agents, waxes, polishes, etc. (

Most obviously there is no further need for a specific regulation regarding adhesives & sealants based on silicones; but we will continue to closely observe this issue.


Current Trends in Key Adhesive Raw Materials

Against the background of a global economy which performs robustly, the demand for base-chemicals remains high - especially in Asia and USA.  As an economically logical consequence of this current "supply and demand mechanisms" - the prices for commodities in these markets are higher than those that can be obtained on the European market.

This effect of arbitrage as well as planned overhauls - but also force majeures - in cracker-plants and facilities dedicated to the production of base-chemicals have a negative impact on the availability of key adhesive raw materials.

In this context, IVK - the German Adhesives Association has published a briefing note & press release informing about the current trends in key adhesive raw materials.

Please find the briefing note/press release "Current trends in key adhesive raw materials" below. Please feel free to share this information.

Current trends in key adhesive raw materials


A holistic approach to the evaluation of in-can preservatives

Industries using preservatives in their products which are placed onto the European market are currently faced with significant challenges for the preservation of those products linked to the technical and regulatory requirements of the Biocidal Products Regulation (BPR, Regulation (EU) 528/2012), as well as to those resulting from other legislation such as the re-classification of individual biocidal active substances under Classification, Labelling and Packaging of substances and mixtures (Regulation (EU) 1272/2008, CLP). As a consequence downstream user industries – such as the adhesive & sealant industry - face an increasingly developing uncertainty of the availability of critical active substances.

In-can preservatives remain fundamental for the effective and safe preservation of water-based products because they control the presence of micro-organisms that may cause deterioration and spoilage – thus, ensuring products remain fit for purpose throughout their intended life. It is, therefore essential to maintain a diverse portfolio of preservatives not only to maintain the multiple products’ performance, but also to protect human health. A wide range of biocidal substances is needed to avoid the development of potential tolerances and resistances.

In this context, a European downstream user expert committee – including experts from the German Adhesives Association - worked out the position paper “A holistic approach to the evaluation of in-can preservatives”.

This position paper which at the same time is an appeal has been presented on the meeting of the EU Member State Competent Authorities Meeting for Biocides in March 2017.

Please share this European position paper/appeal as often as possible!

Holistic Approach - Review of PT 6 in-can preservatives


Database with 750+ documents relevant to adhesive bonding is now online

Experts from IVK have developed a database that contains actually more than 750 documents relevant for the development, production and testing of any kind of adhesive bonded joints. In addition to the relevant German, European and international standards, the database also refers to industry-internal guidelines, technical briefing notes from IVK, and from related customer industry organizations.

The database is equipped with a comprehensive search function, which allows the user to search specifically for relevant subjects. The user receives a brief description of the content of the found document(s) and a link to the reference source.

With this database the German Adhesives Association provides another meaningful tool to improve the safety and reliability of adhesive bonded components.

The database which is only available in German can be found on IVK’s webpage by following this link.

DIN 2304 Part 1 "Adhesives Bonding Technology - Quality Requirements for Adhesives Bonding Processes", now available in English

In March 2016, an IVK expert group comprising adhesives manufacturers, adhesive users and scientists released the new DIN 2304 standard enriching the industry with another important tool for assuring the quality of adhesive bonding processes.

This new DIN standard specifies the requirements for an effective & quality-assured manufacturing process for structural/load-bearing adhesively bonded joints to meet well-defined safety classes. Due to this new standard, workforce qualification will from now on be a mandatory element and therefore an integral part of controlled bonding processes. Companies which work according to this standard do so in the knowledge that they are operating according to the adhesive bonding state-of-the-art.

In just a few months, after the standard was published, this German initiative gained a European-wide recognition and acceptance within the industry, and it was therefore translated into English.

The English version of DIN 2304 Part1 „Adhesives Bonding Technology – Quality Requirements for Adhesives Bonding Processes“ can be obtained from DIN/Beuth-Verlag:

New Image Film released

On the occasion of its 70th anniversary in June 2016, IVK has released the new image film “The fascinating World of Adhesives”.

This 5-minute image-clip explains the basic principles of adhesive chemistry, why adhesives have become indispensable to modern manufacturing processes, and how and why innovative adhesive systems have quietly revolutionized our world. There is hardly any household, craft or industry which does not rely on the use of modern and innovative adhesives, allowing creating completely new degrees of freedom in engineering and design.

It goes without saying that this image film is completely neutral; it does neither contain any kind of advertisement nor product-placements.

“The fascinating World of Adhesives” is available in English and German and it can be watched online, or can be downloaded free of charge on/from IVK’s homepage: Additionally, the image film can be found on IVK’s YouTube channel Klebstoffe.

There is less and less correlation between the price of crude oil and the price of adhesives

Crude oil prices have been falling for two years, and the dollar-per-barrel rate is currently 35 percent below last year’s level. However, the price of crude oil no longer bears a direct relation to that of the end products. One reason for this is the multitude of processing steps along the value chain that determine the end price to a far greater extent than the crude oil price does.

Why the adhesives industry cannot pass on the cuts in oil prices to its customers is best explained by an IVK press release which has been published recently.

Pharaoh Tutankhamun's Death Mask Repaired

Tutankhamun's beard - saved, not shaved

Great agitation at the Egyptian Museum in Cairo. During cleaning work, the world famous mask of pharaoh Tutankhamun was damaged the beard fell off. Finally, this mishap could now be repaired thanks to German adhesive know-how. The world famous artefact withstood more than 3,000 years undamaged until employees of the museum accidentally tore off the royal chin beard of the golden death mask and then tried to provisionally reattach it using a totally inappropriate synthetic resin, resulting in ugly, yellowish traces on the pharaoh' s face.

In order to repair the mishap, the restoration team lead by Christian Eckmann from the Roman Germanic Central Museum in Mainz drew on the expertise and support of German adhesives experts. First, the synthetic resin was removed in a very complex special process leaving no residues. Then, researchers successfully developed a completely new adhesive. In order to be able to repair the beard in a professional manner this newly developed adhesive had to be capable to reliably adhere to pure gold, and at the same time the adhesive bond had to be reversible. Now, the mask is again on display in the Egyptian Museum thanks to adhesive technology "Made in Germany“.

New Education Materials

Almost 10 years ago, IVK - the German Adhesives Association – has started to systematically promote and to support training and qualification activities in the field of adhesive bonding at schools. In co-operation with educationalists and didacts, experts from the German Adhesives Association have developed educational materials and videos to support teachers accordingly.

In the meantime the subject ‘Adhesives & Adhesives Bonding’ has been included in the curricula for chemistry and technical teaching at many colleges and vocational schools throughout Germany.

In order to keep the teaching contents up-to-date IVK has developed and published a fundamentally revised version of its teaching & tutorial materials - comprising a textbook and a CD containing comprehensive descriptions of experiments, graphical material, and worksheets.

This new educational materials will be distributed to more than 17,000 specialist teachers for the subjects chemistry and engineering across Germany, free of charge.

By this means the German Adhesives Industry is thus making another valuable contribution to support school education in the field of adhesives and adhesives bonding.

This revised teaching & tutorial materials which has been published under the title “Die Kunst des Klebens” (The Art of Adhesive Bonding) is only available in German.


New Labelling Requirements deriving from EU Biocide Regulation
The Ball is now in the Yard of the Biocide Manufacturers!

In June 2015 the EU Directives on Dangerous Substances and on Dangerous Preparations expired and the GHS / CLP-System came into force. Thus, all adhesives which contain hazardous substances have to be labeled according to GHS / CLP from June 2015 on. The "new" classification & labelling rules are based, inter alia, on the concentration of a hazardous substance in a formulation. An adhesive, for example, which contains 1.5 – 15 ppm of the preservative MCI / MI in a mixing-ratio of 3: 1 has to be labeled with the risk phrase >> EUH 208: Contains Isothiazolinone mixture 3:1. May produce an allergic reaction <<*


Being involved in various national and European experts groups, IVK - the German Adhesives Association – closely accompanied the development of the content of the GHS / CLP rules, and it therefore was able to inform German Adhesives Manufacturers about the amended legislation at a very early stage. Thus, IVK-members were prepared for the new classification & labelling of their products according to GHS / CLP in full by June 2015.


In the course of its work, IVK was informed that the new EU Biocide Regulation (EU-No. 528/2012) might require additional labelling for “in-can preserved” adhesives, provided that there is a respective entry/reference note in the registration dossier of an active substance under the EU Biocide Regulation demanding additional information/labelling. This additional labeling must be carried out independently of the requirements of GHS / CLP. Different to the GHS / CLP classification & labelling system there are no concentration limits for the "Biocide Labelling".


The first biocide registration dossiers for MCI / MI in the mixing ratio 3:1, for "Folpet" and for "MBM" have been published recently. These three dossiers include mandatory instructions for the labelling of adhesives which contain one of these biocides - irrespective of its concentration in the formulation!! IVK expects that biocide registration dossiers - demanding additional labelling of preserved adhesives – will be published successively in the near future


The labelling in accordance with the EU Biocide Regulation, article 58, paragraph 3 comprises the following information:


a)      statement that the treated article incorporates biocidal products;

b)   where substantiated, the biocidal property attributed to the treated article;

c)    without prejudice to Article 24 of Regulation (EC) No 1272/2008, the name of all active substances contained in the biocidal products;

d)  the name of all nanomaterials contained in the biocidal products, followed by the word ‘nano’ in brackets;

e)    any relevant instructions for use, including any precautions to be taken because of the biocidal products with which a treated article was treated or which it incorporates.


The labelling shall be in the official language or languages of the Member State of introduction, unless that Member State provides otherwise. It shall be clearly visible, easily legible and appropriately durable.


This additional labelling according to the EU Biocide Regulation is mandatory from the date of the approval for the active substance:


  • MCI/MI, 3:1:     July 1, 2017
  • Folpet:             January 1, 2016
  • MBM:              April 1 2017


So far, neither IVK nor the industry has received any information about the additional labelling from the manufacturers of the above mentioned biocides at all!


However, this information is essential for the entire adhesive industry, because an additional or new labelling will entail e.g. software-updates, re-formulations, and/or changes in the packaging supply chain.


All these measures – and there are probably even more parameters to be considered - are time-critical!


IVK therefore urgently recommends to all adhesive manufacturers to get in contact their biocide-suppliers to verify:


  1. whether the registration dossier of the preservative used demands an additional labelling according to 528/2012 Article 58 (3), or whether respective labelling instructions can be expected in the foreseeable future?

    and if the answer is "yes"

  2. what is the exact wording of the labelling according to Article 58 (3), second subparagraph (a) - (e) of the EU Biocide Regulation for the preservative used ?



 * Alternatively, the following wording for the risk phrase EUH 208 can also be found:  >> EUH 208: Contains 5-chloro-2-methyl-3(“H)-isothiazolone and 2-methyl-3(“H)-isothiazolone (3:1). May produce an allergic reaction <<*


New DIN 2304 standard "Adhesive bonding technology – Quality requirements for bonding processes"


A few days ago, the new DIN 2304 standard was released by an expert group comprising adhesive manufacturers, adhesive users and scientists. This means that industry now has another important tool for assuring the quality of bonding processes.


Adhesive bonding is recognised today as an innovative and reliable joining technique which, not without reason, has assumed the mantle as the joining technology of the 21st century.


A study recently published by the NMI* describes adhesive bonding as an established, environmentally compatible joining method having high scope for value creation and having clear competitive advantages over other joining techniques.


From a technological viewpoint, the use of innovative adhesive systems allows components to be manufactured from an almost unlimited number of combinations of different materials. Besides the actual joining function, additional functionalities can also be integrated into modern adhesives – such as electrical and thermal conductivity – making them, for example, integral materials for the development of products such as smartphones and tablets.


The dynamic developments taking place in modern adhesive bonding technology are due, amongst other things, to focused establishment and expansion of system partnerships within the adhesive bonding process chain, to the interdisciplinary research community and to effective workforce training in adhesive bonding technology.


The new DIN 2304 standard "Adhesive bonding technology – Quality requirements for bonding processes" specifies the requirements for manufacturing effective, quality-assured, structural/load-bearing adhesively bonded joints to meet well-defined safety classes. Due to this new standard, workforce qualification will from now on be a mandatory element and therefore an integral part of controlled bonding processes. Companies who work according to this standard do so in the knowledge that they are operating according to the adhesive bonding state-of-the-art.


This initiative – which is at present still confined to Germany – prospectively has both a Europe-wide and global dimension.

"Adhesives Technology Compendium" - Edition 2015


A brand new 2015 edition of the Adhesives Technology Compendium has been published this month.


In a joint project the German Adhesives Association (IVK) and the editors of the magazine ADHESION-Adhesives & Sealants started already back in 2009, to publish the Adhesives Technology Compendium every second year. For the new 2015 edition, the team of authors has been extended to IVK’s fellow associations from Austria (FCIO – Austrian Association of Flooring Adhesives), The Netherlands (VLK – Dutch Adhesives and Sealant Association) and Switzerland (FKS – Association of the Swiss Adhesive and Sealant Industry).

Thus, the newly published reference book now contains the company profiles of more than 160 adhesive & sealant manufacturers, dosing & mixing equipment suppliers, research institutes, as well as consultancy companies and toll manufacturers from these four European countries. Furthermore the compendium gives a survey on the broad activities and committee work of IVK and its sister associations, as well as on European legislation & regulations, statistics and standards, important to the European Adhesives & Sealants Industry.

The Adhesives Technology Compendium is an important element of the communication strategy of the German- & Dutch-speaking adhesive Industries. Therefore 5,500 copies of this reference book will be distributed in Europe, Asia and the US. An e-paper version is also available on the internet:

Hardcopies of the “Adhesives Technology Compendium”, Edition 2015, can be bought at a price of Euro 25, 90 (incl. VAT, plus shipping) from: Industrieverband Klebstoffe e.V., P.O. - Box 26 01 25,

New German Standardization Project
– Quality Requirements for Adhesive Bonding Processes –  

Irrespective of how modern adhesives are defined - as High-Tech or High-Tack products - they are definitely High Quality products allowing a zero-defect-production, provided that the adhesives are properly used.

However, if bonding failures occur, in more than 90 % these failures result from failures in the adhesive bonding process - they do not result from failures of the adhesive.

In order to cope with this situation of having high quality adhesives for a zero-defect-production on the one hand and adhesive bonding failures on the other hand, a new German standardization initiative starts to take effect: the Draft Standard DIN 2304-1 (Norm-Entwurf DIN 2304-1:2015-05) describes and implements quality standards for the proper use of adhesives. It determines the current state of the art for the organization of a proper realization of adhesive bonding processes in user-companies. Furthermore, the quality of the adhesive bonding process will catch up with the quality of the adhesive production process.

For the time being, the scope of DIN 2304-1 is restricted to the production of structural/load- bearing adhesive bonds in defined safety areas, while the assembling of adhesive bonds which are already regulated – for instance laminated wood panels - are exempted from the scope of the standard.

However, DIN 2304-1 is at any time ready to be applied to other areas than structural bonding. It could be used as a meaningful tool for craftsmen or any other manufacturing industries to improve their market positions in a competitive environment. However, before the scope of DIN 2304-1 can be extended to other adhesives applications a solid knowledge-base on adhesive bonding has to be developed and to be integrated into the curricula of the various educational processes.  In co-operation with customer organizations all along the value chain the German Adhesive Association will trigger this initiative.

IVK - the German Adhesives Association considers DIN 2304-1 to be another meaningful milestone to further increase the perception and the reliability of adhesives bonding – also beyond the German borders. Therefore it strongly supports this standardization project with expertise, advice, related initiatives, and it will also seize the opportunity to introduce the standard internationally.

Successful Annual General Meeting 2015 in Bremen

The Annual General Meeting 2015 of IVK - The German Adhesives Association – which took place in June in Bremen was again a great success. The conference was attended by almost 250 people from 95 member companies - thus, 78% of the member companies were represented.

This record number is an impressive indication of the high priority which the IVK enjoys among its members.

IVK offers its members valuable networking opportunities and important information, tailored to the Adhesives & Sealants Industry. In 18 different meetings of the various technical and business working groups which took place during the conference, the members were informed about the current technical work and the latest market trends in the different key-market sectors.

In 2014, the German Adhesives and Sealants Industry could increase its total business by 2.6 % - now representing > 25 % of the total European consumption, > 32 % of the total European production, and holding a global market share of 18 %. For 2015, IVK members expect a robust economy with a growth-rate up to 3 %.

The German Adhesives Association is the world’s largest and - with respect to its broad service portfolio - at the same time the world’s leading national organization in the field of adhesives bonding technology.

German Authorities plan Olfactory Testing for Construction Products

The German Committee for Health-related Evaluation of Building Products (AgBB) has initiated a project for the evaluation of a test method for olfactory/odours testing of construction products. Due to the fact that the entire range of construction adhesives is subject to this future test- and classification method, experts from the German Adhesives Association (IVK) were involved in this project. They participated in 2 round robin tests which required technical and financial contribution.

Originally based on technical specifications of the international standard ISO 16000-28 “Indoor air - Determination of odour emissions from building products using test chambers”, elements of the German Industry Standard VDI 4302 “Sensory testing of indoor air and determination of odour emissions from building products – Test Strategies as well as several standard operational procedures (SOPs) have been included into this draft olfactory test method. However, the scatterings of the results between the institutes participating in the round robin tests are enormous due to this highly subjective matter. Despite this significant deviation in the test results the German authorities will obviously stick to their plan to introduce olfactory/odours testing.

The main driving force behind this project is the German Federal Environmental Agency (UBA) which plans to integrate the sensory test - including a classification scheme - into the list of requirements for the German Eco Label ‘Blue Angel’. For the time being it is still unclear and an ongoing discussion whether olfactory testing will in future also become part of construction product requirements issued by the German Institute for Building Technology (DIBt).

On October 1/2, 2015 there will be a conference in Dessau, Germany, to present the results of the evaluation of this test method. IVK as all the other participating industry associations see neither need nor relevance for putting olfactory tests on building products. Moreover, the chosen test does not deliver the accuracy for a reliable quality statement on odours.

New ISO Standard
17178 “Parquet Flooring Adhesives”

With the publication of the new international standard ISO 17178 “Adhesives for bonding parquet to subfloor - Test methods and minimum requirements” experts from the German Adhesives Association (IVK) have successfully managed to globally introduce the latest state of the art for parquet flooring adhesives. This new ISO Standard is the result of a pro-active engagement of experts from IVKs Technical Committee “Flooring Adhesives”.

The new ISO 17178 is based on the technical specifications of the European Standard EN 14293 "Adhesives for bonding parquet to subfloor” which is recognized by craftsmen throughout Europe. ISO 17178 describes tests and defines minimum requirements for
hard, hard-elastic, and - for the first time ever – also for soft parquet flooring adhesives. This new classification reflects the latest development in the formulation of soft parquet flooring adhesives, based on PUR and SMP - also at an international level. In the German market these adhesive systems have in the meantime almost completely replaced solvent-based parquet flooring adhesives. This is another active contribution of the German Adhesives Industry with respect to occupational Health & Safety, Environment- and Consumer Protection - ready, to be globally implemented.

“The active professional support of standardization projects which are crucial for the adhesive industry – even at the international level - is an important tool in the strategy of the German Adhesives Association. IVK is at any time prepared to safeguard the global competitiveness of the German Adhesives Industry,”
says Ansgar van Halteren, CEO of the German Adhesives Association.

Consumption of Organic Solvents in Adhesive Production continues to decline

The consumption of organic solvents in the production of adhesives in Germany continues to decline. Over the past 20 years, the German Adhesives Industry has successfully reduced the use of organic solvents by more than 30%. During the same period the production volume grew by more than 70% to currently 877.000 tons/year. The share of solvent based adhesives which are used in the market segment “Flooring / Parquet-Flooring” is < 1%. These figures emphasize the innovative power and the extraordinary commitment of the German Adhesives Industry in the field of Safety, Health & Environment.


Industry specified VOC test method for adhesive tapes

The automotive industry demands from the tape manufacturers concrete statements regarding the VOC (Volatile Organic Compounds) values of adhesive tapes. In collaboration with the Forschungsinstitut für Leder und Kunststoffbahnen Freiberg (FILK) the Technische Kommission Klebebänder (TKK) of the German Adhesives Association has evaluated different test methods and decided that the VDA 278 "Thermal Desorption Analysis of Organic Emissions for the Characterization of Non-Metallic Materials for Automobiles "of the Association of the Automotive industry (VDA) is the most appropriate method for adhesive tapes. The focus of this method lies – due to its semiquantitative character – essentially more in the identification and less on the exact quantification of critical substances. From the perspective of the adhesive tape manufacturers the most important determining parameters for a tape specific clarification of the VDA 278 have been defined and specified by the TKK. The overall concept and the approach will be discussed next with the VDA.

Information on First Aid Measures in case of an Accident with Superglue now available in English

Experts from the German Adhesives Association have prepared and published an Information leaflet on First Aid Measures in case of an Accident with Superglue. Cyanoacrylate Adhesives commonly sold as superglue, instant glue, power glue, magic glue or NASA glue, etc. are very fast curing products with high bonding characteristics. Within seconds, they can bond human tissue, including skin or eyes. Experience has shown that with proper procedures in case of accidents, surgical interventions are not necessary as long as some essential instructions and procedures are complied with. These essential instruction procedures are described in the information leaflet which is now available in English.

European Court of Justice:
German Trade Barriers violate EU Construction Law

The European Court of Justice decided that additional legal requirements in Germany on CE-marked construction products violate the principles of free trade. Instead of keeping to the procedures set by the Construction Products Directive German authorities (DIBt – Deutsches Institut für Bautechnik) have enforced their own additional approval system requiring a separate “Ü-mark”. Companies from abroad, lawyers and trade associations complained against the complicated and bureaucratic system in Germany discriminating producers from other EU countries.

Although decided for tube gaskets, insulating materials and doors, the decision of the European Court is of basic significance. For products which are subject to harmonised European standards there is no competence for specific national requirements at all.

Online “Adhesive Bonding Guide” – now available on Internet

Adhesive Bonding is a special process with a broad variety of diversified applications, and a huge number of quality influencing factors. Even more many users of adhesives are often not aware of the technological requirements of the adhesive bonding technology.

For this reason experts from IVK and Fraunhofer IFAM have developed the Online-Tool “Adhesive Bonding – the right way!”. It is designed for general applications of adhesives and quality assurance of bonded joints, and it covers all technological aspects from product planning to repair and recycling.

This Online-Tool aims at to enable the user of adhesives identifying quality influence factors and choosing suitable methods of quality assurance.

The Online-Guide provides the basic knowledge of the adhesive bonding technology in order to avoid failures with respect to adhesive selection and –application. This Online-Tool is a perfect complement for workforce qualification at intercompany level, for consulting of customers, and for product training carried out by adhesive producers.

This Online-Guide addresses all users of adhesives, it is not limited to a specific industrial sector, and the use of this Online-Guide is free of charge.

Environmental Product Declarations now also available in English

The new EU-Construction Products Regulation (CPR-EU 305/2011) demands the declaration of reliable information on sustainability of construction product if regulated by a harmonized EN-Standard or a European Technical Assessment (ETA). In this context IVK joined forces with the paint and construction chemicals industry, and experts from these 3 branches developed Environmental Product Declarations (EPDs). EPDs are available for construction products based on dispersions, epoxy-resins, polyurethanes/silanes, and mineral mortars. In total there are 16 “Model-EPDs” broken down into more than 155 “Specific-EPDs” specifically describing applications of the various construction products in buildings. The structure and the content of the EPDs strictly follow the specifications of ISO 14025; furthermore the EPDs are certified by the German Society of Sustainable Construction (DGNB – Deutsche Gesellschaft für nachhaltiges Bauen). Manufacturers of construction- & flooring installation products are now put into the position to comply with the new EU-CPR. In order to support its members regarding their European & global businesses the “Model EPDs” will successively be translated into English. 8 EPDs are already translated and available.

Typical Product Carbon Footprint-Values for Industrial Adhesives

The recent discussion on sustainability has triggered an increasing interest in Carbon Footprint values of both, products and processes. In spite of the fact that the amount of adhesives in a bonded product is relatively small; still, adhesives manufacturers are being asked for Product Carbon Footprint (PCF)-values of the adhesives they supply. In order to support IVK-members in respective discussions with their customers, an IVK expert-group has calculated typical PCF-values (cradle to grave) for the following product groups: adhesives based on water-based dispersions, thermoplastic hot melt adhesives, solvent based adhesives, and reactive adhesives.
