ONE PART CURABLE COMPOSITIONS CONTAINING DEACTIVATED HYDROSILATION CATALYST AND METHOD FOR PREPARING SAME

摘要

The catalyst inhibitors of the present invention react with conventional platinum group metal-containing hydrosilation catalysts to form complexes that delay curing of compositions containing these complexes in the absence of oxygen and SiH-reactive hydroxylated compounds. The curable 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.
