Abstract

Stable curable silicone compositions, well suited for the deposition of release coatings onto a wide variety of substrates, for example paper or plastic films, comprise a hydrosilylation-curable polyorganosiloxane oil and/or at least one Si alkenylated organopolysiloxane resin and, optionally, at least one organohydrosiloxane resin, an SiH crosslinking agent therefor, a hydrosilylation-inhibiting amount of a long chain acetylenic alcohol, advantageously having a boiling point higher than 250.degree. C., and a catalytically effective amount of a hydrosilylation catalyst, e.g., platinum or a platinum compound/complex.
