Abstract
A primerless, one-part, heat curable, low volatile organic compound, polyurethane composition comprises a blocked polyurethane prepolymer made from a liquid hydroxyl terminated intermediate and an excess of a polyisocyanate, a curing agent, silicone and/or low friction polymer and optional fillers. Upon cure of the polyurethane composition, the silicone oil and/or low friction polymer generally imparts low friction and high abrasive resistant properties. A desired use is as a glass run channel coating.
