This invention claims a silicone release coating composition comprising an organopolysiloxane having at least 2 alkenyl groups in each molecule, annorganopolysiloxane having at least 3 silicon-bonded hydrogen atoms in eachnmolecule, na carbon-carbon triple bond-functional alcohol having a boiling point at ambientnpressure, nof at least 140°C, an organosilicon compound having at least 3 carbon-carbonntriple nbond-functional hydrocarbon groups bonded across oxygen to silicon, and anplatinum ncatalyst. These release compositions have excellent bath stability, form a verynstable film on applicator rolls, cure rapidly even at low temperatures, have stable curingncharacteristics during bath aging, and exhibit stable release values duringnbath aging. |
