Royal DSM is a global science-based company active in health, nutrition and materials. By connecting its unique competences in Life Sciences and Materials Sciences DSM aims to drive economic prosperity, environmental progress and social advances to create sustainable value for all stakeholders simultaneously. In the area of Coating Resins and Functional Materials (DRF), DSM is particularly interested in novel, sustainable and possibly renewable approaches towards water-based coatings, and we have in the past brought new products such as water-borne alkyds and polyurethane dispersions to the market with renewable contents. These materials were based on polycondensation, urethane and free radical polymerization methodologies. For these water-borne coating resins DSM Coating Resins is still looking for well-performing, novel synthesis routes towards water-based polyurethane dispersions via alternative and more environmentally benign building blocks instead of the use of isocyanates.
