One part curable compositions containing deactivated hydrosilation catalyst and method for preparing same

U.S. Patent Number: 5380812

Abstract: The catalyst inhibitors of the present invention react with conventional platinum group metal-containing hydrosilation catalysts to from complexes that delay curing of compositions containing these complexes in the absence of oxygen and SiH-reactive hydroxylated compounds; the compositions comprise (1) curable compounds containing alkenyl radicals and/or silicon-bonded hydroxyl groups, (2) curing agents containing silicon-bonded hydrogen atoms, and (3) a platinum group metal-containing hydrosilation catalyst. Preferred inhibitors provide long term storage stability.
