Silicone structures impart versatile properties

Tuesday, 6 April 2010

New surface-modifying additives have a lower silicone content than established modified silicones and can be adjusted for specific applications.

Silicone-modified polyacrylates represent a new class of surface-modifying additives. From a chemical perspective, they are hybrids composed of silicone chains securely bonded to a polyacrylate chain, and generally have a lower silicone content than established modified silicones. Versatile chemistry and modular molecular structure make it possible to adjust their properties for specific applications. Additives with a high silicone content can impart anti-graffiti properties to coating surfaces. Types with a lower silicone content can reduce surface tension and improve substrate wetting without impairing recoatability. Read a detailed paper on this subject in the latest issue of EUROPEAN COATINGS JOURNAL.
