| abstract |
The present invention relates to organopolysiloxanes having two or more alkenyl groups in each molecule, organopolysiloxanes having three or more silicon-bonded hydrogen atoms in each molecule, and carbon-carbon triple bond functionality having a boiling point of 140 ° C. or higher at ambient pressure. A silicone release coating composition comprising an alcohol, an organosilicon compound having at least three carbon-carbon triple bond functional hydrocarbon groups crosslinked to silicon via oxygen, and a platinum catalyst. These release compositions have excellent bath stability, form very stable films on applicator rolls, cure rapidly at low temperatures, have stable curing properties during bath cure, and exhibit stable release values during bath cure. |
