Development of Innovative Adhesives Using Renewable Raw Materials

A research team from the Fraunhofer Institute for Environmental, Safety and Energy Technology (UMSICHT) is working on two projects to develop new adhesives using renewable raw materials. The team is developing a pressure-sensitive adhesive for industrial uses in collaboration with Novamelt, Logo tape and Jowat, University of Applied Sciences, and the Westfälische Hochschule. The major challenge for the UMSICHT team was to develop a backbone polymer from polylactic acid, a material well-known for its low production cost. The acid's properties are entirely different from the polymers that have been used to date, such as styrene-based block copolymers and polyacrylates. In another project, researchers from UMSICHT are jointly working with Deckert Management Consultants, Jowat, and Achilles Papierveredelung Bielefeld to develop novel water-based dispersion adhesives for laminated products. Dosima fascicularis, the buoy barnacle, produces a special biological adhesive, which becomes extremely strong and is difficult to break down using standard solvents. It also has the capability to cure under water. Scientists from the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) are currently working to discover which amino acid components form the relevant proteins.
