Vegetable Oils Could Change Sustainability of Adhesives and Resins

Posted on 5/22/2019 7:16:24 AM By ASC

Increased demands for sustainability at all levels of product manufacture has the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) putting vegetable oils under the microscope. This is to determine these oils’ potential as alternatives to petroleum-based chemicals in the production of coatings, adhesives and paints. 

Scientists at IMWS are also working on using these oils to develop a new breed of solvent-free adhesives with an organic content of 86% - more than double the 35% required for qualification as a sustainable material. To do so, they are testing a different way of processing them at a lower temperature, and without petrochemicals, by using enzyme treatment rather than epoxidation, and have found a way to replace the toxic hardener with an eco-friendly alternative. 

At the same time, research is continuing into the possible effects the varying chemical compositions of the raw materials extracted from different plant seeds will have on the properties of the resins produced.
