Abstract
The thermosetting silicone composition of the instant invention is comprised of (a) a diorganopolysiloxane containing alkenyl groups, (b) an organohydrogenpolysiloxane, (c) a platinum catalyst-containing silicone resin fine particle catalyst comprised of (i) a thermoplastic silicone resin containing 5 to 90 mole % PhSiO.sub.3/2 siloxane units and 5 to 20 mole % MeViSiO.sub.2/2 siloxane units, wherein Ph denotes phenyl, Me denotes methyl and Vi denotes vinyl; said resin having a glass transition point of 40.degree. to 70.degree. C. and (ii) 0.05 to 2 wt % as platinum atoms of a platinum catalyst; and (d) a hydrosilation reaction inhibiting compound. The thermosetting silicone compositions have excellent storage stability at about room temperature, and cure at a fast rate when heated.
