Cologne, Germany — Covestro is working with the technical University of Cologne in project into polyurethane dispersions (PUD).
Applied research on dispersed colloidal polymers is running for three years. Around EUR 600,000 funding comes from the German Federal Ministry of Education and Research.
Michael Friede is global head of Covestro’s coatings, adhesives, specialty segment. He said Covestro is involved because ‘paint and adhesive manufacturers are increasingly opting to replace solvent-based products with more sustainable aqueous systems.’
In addition, ‘this will create growth opportunities and strengthen the competitiveness of our customers,’ he said.
The project’s first goal is to optimise manufacturing processes. Secondly, the project aims for a better understanding of how the structure and properties of the dispersions are related.
‘We focus on application-oriented research of PUDs and rapid market launch of new products,’ said Jan Weikard, an expert in the polyurethane dispersions division.
Film formers, or binders in paints for initial and refinishing of cars; in paints for wood and furniture; and, as floor coverings are common PUD uses. Textile coatings and glass fibre coatings also use PUDs. In addition, adhesives for furniture, shoes and automotive components often use PUDs.
