DYNACOLL® based 2C hot melts –New adhesive systems with high initial strength for (semi-)structural bonding of composite materials for automotive applications

AUTOMOTIVE

Lightweight constructions are key elements for saving power and reducing emissions of cars. The automotive industry is searching for new bonding solutions to join dissimilar materials like CFR plastics and metal. In general, polyurethane systems are well suited to provide high elongation and shear strength. Typically used 2C liquids for (semi)-structural bonding need to be accelerated by catalysts and heat to build up sufficient handling strength. Further primers are requested to provide good adhesion to CFRP.

DYNACOLL® polyester polyols are well established for formulating 1C PU hot melts. After application of the adhesive at moderate temperatures, the parts set bond quickly, resulting in short cycle times that allow fast downstream processing of the bonded substrates. The subsequent crosslinking by moisture, such as atmospheric moisture, leads to bonds with high final strength and temperature resistance. However, there are limitations in using 1C PU hot melts in case of thick bondlines as the curing speed is depending on moisture permeability and in providing very high cohesive strength for structural bonding.

2C PU hot melts are a new approach to offer high productive adhesive solutions with high cohesive strength to the automotive industry due to the hot melt character and increased crosslink density. Therefore innovative concepts based on new linear and branched DYNACOLL® polyester polyols were developed.

POLYVEST® EP ET – Epoxy-terminated liquid poly- butadiene improves performance of heat-curable rubber-based body shop adhesives and sealants

AUTOMOTIVE

With POLYVEST®, Evonik’s Adhesive Resins Product Line offers a range of stereospecific, low viscous and unsaponifiable liquid polybutadienes. Based on their unsaturated and nonpolar polymer backbone all POLYVEST® grades exhibit a superior low glass transition temperature (-80 to -100 °C), an excellent reactivity towards curing via vulcanization and a good compatibility with process oil. Due to these unique properties, POLYVEST® is highly suitable for being used as low viscous reactive plasticizer in rubber-based body shop adhesives and sealants. Adhesives and sealants based on POLYVEST® can be directly applied on oily substrates and do not migrate or bleed-out after the curing step via vulcanization.

Furthermore, the adhesion performance of rubber-based adhesives and sealants can be improved by application of commercially available functional POLYVEST® grades, e.g. hydroxyl-terminated POLYVEST® HT and anhydride modified POLYVEST® MA 75.

Recently, the product portfolio has been expanded by another unique functional polybutadiene: POLYVEST® EP ET – an epoxy-modified polybutadiene with a tailormade molecular structure that provides exclusively terminal epoxy moieties and an unsaturated polybutadiene backbone. Based on its unique structure it can undergo a chemical reaction with its epoxy groups and the double bonds. POLYVEST® EP ET also shows an excellent compatibility in rubber-based adhesives and sealants and it facilitates a further improved adhesion on polar substrates like steel or aluminum.

Its bifunctional structure allows dual-curing via vulcanization and epoxy-curing. The additional epoxy- curing step, e.g. by using latent amine hardener like dicyandiamine in combination with bisphenol A epoxy resins as co-binders, leads to improved tensile and lap shear strength of the formulation.

Well connected and free. The culture of innovation at Coating & Adhesive Resins.

Interview with Dr. Lutz Mindach, Head of Innovation Management, Coating & Adhesive Resins.

Dr. Mindach, since the beginning of March you have been in charge of global research activities at the Coating & Adhesive Resins Business Line. How important, in your opinion, is innovation for the development of the business and what role does the customer play in this process?Innovations are an essential driver of growth in our industry. Early identification of trends and the development of new solutions for the challenges of the future can only take place with input from our customers. This close collaboration is a critical factor for our mutual success. For us, innovation is therefore just the solution that adds value for customers.

What are the prerequisites for achieving this?In my view, an open, innovative culture is vital to collaboration. Such a culture admits mistakes and allows for freedom. This leads to new ways of thinking and gives us the chance to incorporate new perspectives. We also integrate the global organization so that we work not only on new topics but also the right topics.

Another important element is our staff. Our research team is comprised of young, “hungry” researchers who are extremely well connected, both internally and externally. This often provides completely new stimulus that injects an incredible momentum into our work. We critically assess existing solutions and aim to conduct active, open discussions with the development partners with which we are ultimately working toward a common goal.

What makes Evonik an attractive partner for joint development projects?Analysis and knowledge of what customers need is the basis of our innovations. Like virtually no other raw material manufacturer, we are focusing squarely on the trends and developments in the adhesive and sealant industry. Our wide range of attractive technology platforms (polyolefins, polyesters, poly-(meth)acrylates, and polybutadienes) gives us a broad base. We have mastered these technologiesfor decades, in other words, we draw on expertise that we have built up over many years – but without forgetting to continuously develop and expand the portfolio.

We achieve this progress by working as an open partner in collaborative ventures and joint projects. In the process, we deliver not only new products but also customized technology solutions. We don’t necessarily have a special class of polymers in mind when developing these – our goal is primarily the final performance of the adhesive system.

How do you ensure that you are always at the cutting edge of technology?This starts with recruitment. We specifically choose young polymer experts who are straight out of university. We also work in various partnerships within our projects with universities, arrange for special topics to be researched in Bachelor and Master theses, and are very well connected with not only student groups but with other adhesive experts and associations as well. Ultimately, however, it is also the intensive exchange of ideas and experience with our customers that sets the direction for us.

How do you approach new issues?Because our resources are limited, statistical methods in the design of experiments and simulation methods are becoming increasingly important for us in polymer design, as is utilizing Evonik’s internal expertise, such as incorporating many different fields of engineering (for example in relation to interfacial and particle phenomena), and making use of internal networks such as industry teams and Evonik project houses. The teams integrated in this way ensure a holistic approach for us and our customers.

What can we expect in the future?The solutions shown in this brochure for a wide range of applications are already successful examples of our diverse activities with partners such as universities, equipment manufacturers, and end customers. These success stories reinforce our belief that we should continue in the same vein, giving a further boost to our business line’s innovative capacity. Looking at our current pipeline of activities, I can promise that we will support our customers in the near future with further attractive innovations.

Dr. Lutz Mindach studied chemistry at the Universities of Cologne and Mainz before doing a PhD at the Max Planck Institute for Polymer Research. In 1996, he started working in the research department of the Coating Raw Materials unit of the former Hüls AG. After holding several positions in research, applied technology, and marketing, he has headed up the global research activities of the Coating & Adhesive Resinsv Business Line at Evonik Resource Efficiency GmbH since March of this year.

POLYVEST® EP ST – Liquid polybutadienes with combined product features of silane and rubber technologyWith POLYVEST® EP ST, Evonik’s Adhesive Resins Product Line has developed liquid silane-terminated polybutadienes that combine the beneficial product features of rubber and silane technologies.The silane-terminated grades are based on a liquid polybutadiene homopolymer with a unique microstructure and a superior low glass transition temperature of approx. -80 °C. In addition to the reactive unsaturated polybutadiene backbone, the versatile applicability of POLYVEST® EP ST is facilitated by its terminal-alkoxysilane functionalities that allows, e.g. the surface modification of inorganic fillers, adhesion promotion on polar substrates or a moisture-initiated curing.

By using POLYVEST® EP ST as an additive or co-binder in rubber-based adhesives and sealants, the dispersability of inorganic fillers, e.g. silica can be significantly improved. The unsaturated polymer backbone of POLYVEST® EP ST also facilitates a reactive incooperation into the rubber compound via, e.g. suphur vulcanization, which prevents migration effects and improves the overall mechanical properties of the final rubber-compound. Depending on the required reactivity of the alkoxysilane moieties we are offering you a triethoxysilane- (POLYVEST® EP ST-E) or a more reactive trimethoxysilane-terminated (POLYVEST® EP ST-M) grade.

Designed Polymers: DYNACOLL® AC 1632Tailored polyacrylate for flat lamination adhesivesCONSTRUCTION

DYNACOLL® AC 1632: Tailored polyacrylate for flat lamination adhesives, especially chalk filled PU hot melts with improved heat and storage stabilitySince many years reactive PU hot melts (RHM) are successfully used for flat lamination applications like panel bonding or sandwich constructions. The adhesives provide long open times to permit long handling times and high initial strength to hold the bonded parts in place without any further mechanical fixation.

EVONIK is the sole supplier who offers a full range of dedicated polyester polyols and polyacrylates enabling the formulation of RHM which meet these specific requirements. The polymers are marketed under the brand DYNACOLL®.

Pure polyester polyol based RHM formulation with long open time often do not provide sufficient initial strength. Modification with DYNACOLL® AC polyacrylates lead to high creep resistance due to their molecular weight. The product portfolio of bead polymers made of methyl methacrylate and n-butyl methacrylate with acid and hydroxyl functionality has an overall specification range of molecular weight of 30,000 to 140,000 and glass transition of 44 to 85 °C.

DYNACOLL® AC 1630 with molecular weight 55,000 is well established for general purpose flat lamination RHM. Its high acid number leads to good adhesion especially to metal. However, the acid number can infringe the stability of RHM in case of using chalk as filler for cost savings.

Now, a modification called DYNACOLL® AC 1632 with lower acid number and slightly higher molecular weight of 65,000 was developed providing improved heat and storage stability of chalk-filled RHM.

Contact: Gabriele Brenner, [email protected]

Unique properties • Medium acid number• Easy to handle bead polymer• High tack• High creep resistance

Your benefit• Improved storage stability of chalk filled RHM• Balanced adhesion performance• Short dilution times• Short cycle times allow cost-efficient production runs
