After extension of the DYNACOLL® 7000 modular system of Evonik Industries AG, Essen, with polyesters made from renewable raw materials now Jowat AG, Detmold, introduces their first reactive PUR hot melt based on DYNACOLL® Terra.
The DYNACOLL® product range began its success story back in the late 1980s. At that time, Evonik’s development of co-polyesters containing hydroxyl groups crucially influenced the engineering of one-component moisture-curable hot melts. The building block system of compatible amorphous, liquid and crystalline types of DYNACOLL® enabled the precise formulation of reactive PUR hot melts for the most diverse applications in the adhesives and sealants industry. While this modular system of more than 20 medium-molecular options has been constantly adapted and further developed to meet the latest market demands, the addition of polyester made from renewables now introduces a revolutionary new chapter in the DYNACOLL® story.
"We began raw material screening a little over a year ago", reports Gabriele Brenner, who is in charge of technical service for Reactive Hot Melts at Evonik. "The aim was to include the synthesis of amorphous, liquid and crystalline polyesters in the DYNACOLL® Terra product range. Not only did we wish to use green components, but we wanted to achieve product properties comparable with, or even better than those offered in the existing product portfolio."
The result of intensive research, Evonik now introduces six development products with a broad spectrum of properties. The individual products contain between >30 and 100 percent monomers derived from renewable resources. These polyesters can be variously combined in adhesive formulations. Good adhesion properties have already been achieved on a variety of substrates, particularly wood and plastics.
In close cooperation with one of our strategic partners, Jowat AG in Detmold, several adhesive formulations have been developed and adapted to the requirements for specialized applications. At the leading trade fair for the wood and furniture industry, the Ligna in Hanover, Jowat will present for the first-time a reactive PUR hot melt adhesive for edgebanding on the basis of DYNACOLL® Terra. "More than 70 percent of the raw materials used in Jowatherm-Reaktant® 607.80 are based on renewable resources", explains Armin Erb, Head of the Technical Support & Service group at Jowat. "In our conception of being one of the important market and technology leader, we provide our customers with adhesive systems that are not only advantageous in application but also ecologically sustainable. The DYNACOLL® Terra polyesters open up entirely new opportunities for us in regard to bonding renewable raw materials, like wood respectively wood-based products."
At the same time, Evonik’s Adhesive Resins Product Line is continuing the search for suitable monomers from renewable resources. According to their promise "Designed Polymers for Adhesives & Sealants" the DYNACOLL® Terra product portfolio will be expanded and optimized systematically. By developing DYNACOLL® Terra, Evonik has underscored its responsible corporate position and is driving the trend in the chemicals industry on the way to a greener future.
