ABSTRACT:
A storage stable, one part, heat curable organosilicon composition is prepared by mixing an organosilicon polymer having at least two monovalent hydrocarbon radicals containing aliphatic unsaturation, a platinum catalyst, an acetylenic alcohol, and a siloxane compound having at least three silicon-bonded hydrogen atoms bonded to at least three separate silicon atoms; heating above 100.degree. C.; cooling below 50.degree. C.; removing excess acetylenic alcohol; and adding an organosilicon compound containing silicon-bonded hydrogen atoms to yield the organosilicon composition. The method produces an inhibitor for the curing reaction during the process of manufacture so that the composition is storage stable even though all the ingredients necessary for cure are present in the composition.
