Silicone release coating compositions

摘要

This invention relates to a silicone release coating composition comprising (A) a diorganopolysiloxane having at least two alkenyl groups in each molecule, (B) an organohydrogenpolysiloxane having at least three silicon-bonded hydrogen atoms in each molecule, (C) a mixture of an alkynyl alcohol and an organosiloxane having at least one aliphatic triple bond-containing alkoxy group, and (D) a piatinum group metal catalyst. The silicone release coating compositions of this invention have superior curability and storage stability at room temperature. and produce a uniform coating when used in thin film form on applicator rolls.
