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.
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: http://www.beuth.de/en/standard/din-2304-1/245690516http://www.beuth.de/en/standard/din-2304-1/245690516
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: www.klebstoffe.com. Additionally, the image film can be found on IVK’s YouTube channel Klebstoffe.
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.
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“.
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.
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:
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:
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 <<*
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.

Sicheres Kleben – Herausforderungen in der klebtechnischen Praxis,
Astrid Wagner, Alfred Stett
Reutlingen, March 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: http://www.adhesivetechnologycompendium.de/.
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,
D-40094 Düsseldorf – or by email: email@example.com.
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.
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.
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” http://www.beuth.de/en/standard/din-iso-16000-28/165785344, elements of the German Industry Standard VDI 4302 “Sensory testing of indoor air and determination of odour emissions from building products – Test Strategies http://www.beuth.de/en/technical-rule/vdi-4302-blatt-1/224207002 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.
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.
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.
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.
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.
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.

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.
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.
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.
