Method of making integral molded silicone products with different phases and the molded products prepared therefrom

摘要

Integral silicone molded products comprising a unitary structure of a substrate with different phases is made by coating a substrate with a mixture of an alkenyl containing polyorganosiloxane, a polyorganohydrogensiloxane, and an addition-reaction catalyst where at least one component is applied to the substrate and then additional components are applied and diffuse to result in a coating with a polyorganosiloxane phase whose degree of crosslinking is low and a polyorganosiloxane phase whose degree of crosslinking is high and the phase having the low degree of crosslinking is next to the substrate. Such molded products are coated hybrid IC transistors, solar battery modules, and optical fibers.
