Abstract

A reaction produce which includes a reactive silicone, a polyol, and an isocyanate. The reactive silicone may contain polyol or polyamine functionality. A urethane-siloxane copolymer of polydialkyl siloxane and polyurethane. A coating composition which contains a prepolymer of polydialkyl siloxane and polyurethane. A coated article may be produced wherein the article is coated with a composition that includes polydialkyl siloxane-polyurethane copolymer. A method for making a coating composition includes copolymerizing at least one reactive silicone, at least one polyol, and at least one isocyanate. A single-component coating which includes a polydialykl siloxane-polyurethane copolymer. A prepolymer in solution, wherein the prepolymer includes polydialkyl siloxane-polyurethane copolymer and a solvent, such as xylene.
