TEMPERATURE-RESISTANT AND/OR NONWETTING COATINGS OF CURED, SILICON-CONTAINING POLYMERS

摘要

Surfaces of various types of substrates, including glass, ceramics, metals and fabrics, are rendered thermally stable by treatment with a silicon-containing polymer which may be a polysilazane, a polysiloxane, or a polysiloxazane. The process is also useful for rendering metallic surfaces corrosion-resistant. Curing the polymer in an atmosphere which contains an oxygen donor additionally renders the substrate surface nonwetting.
