摘要： This invention relates to a silicone release coating comprising (A) an organopolysiloxane having at least two crosslinkable carbon-carbon double bonds in each molecule, (B) an organopolysiloxane having at least two Si-bonded hydrogen atoms in each molecule, (C) a silylated polymethylsilsesquioxane and (D) platinum catalyst. The silicone release coating compositions of this invention can further comprise an inhibitor. The silicone release coating compositions of this invention do not decline in release resistance due to release paper aging or release liner aging.
