摘要： The present invention relates to a method of making silicone release coating compositions comprising mixing a vinyl functional organopolysiloxane, an organohydrogensilicon compound, a platinum group metal-containing catalyst, and certain silylated acetylenic inhibitors. The present invention further relates to a method of making silicone release coating compositions comprising mixing an organopolysiloxane compound having alkenyl groups which contain at least four carbon atoms, an organohydrogensilicon compound, a platinum group metal-containing catalyst, and a silylated acetylenic compound having its formula selected from the group consisting of: HC≡C—Q—O—Si—(R3)3, HC≡C—Q—O—Si(R3)2—O—Q—C≡CH, and H—Si—(O—Q—C≡CH)3 where R3is independently selected from the group consisting of hydrogen, monovalent hydrocarbon radicals free of aliphatic unsaturation, and an alkenyl group, and Q is a divalent hydrocarbon radical at least 3 carbon atoms, with the proviso that there is at most one silicon-bonded hydrogen group or one silicon-bonded alkenyl group per silylated acetylenic compound.
