Silicone composition for mold release

Abstract

Abstract PURPOSE:To provide the titled compsn. which is effective even in a small quantity, by mixing an organohydrogen-polysiloxane, an organopolysiloxane contg. aliph. unsaturated hydrocarbon groups, a perfluoroalkyl group-contg. compd. and a platinum catalyst. CONSTITUTION:An organohydrogenpolysiloxane (A) having a siloxane unit of formula I (wherein R<1> is a monovalent satd. hydrocarbon group; a+b<=3) in the molecular chain, an aliph. unsaturated hydrocarbon group-contg. organopolysiloxane (B) having a siloxane unit of formula II (wherein R<2> is a monovalent aliph. unsaturated hydrocarbon group; R<3> is a monovalent satd. hydrocarbon group; c+d<=3) in the molecular chain, a C4-C20 perfluoroalkyl group-contg. compd. (C), e.g. perfluorooctylethylene, and a platinum (compd.) (D), e.g. a complex of chloroplatinic acid and a vinylsiloxane, are mixed together to obtain the desired silicon compsn. for mold release.
