Patent abstract
In a one part organopolysiloxane gel composition comprising an alkenyl-containing branched organopolysiloxane, an SiH-termined organohydrogenpolysiloxane, and an addition reaction catalyst, the catalyst is obtained by heat aging a mixing of a platinum complex having an alkenyl-containing silane or organosiloxane as a ligand, a phosphite, and an organohydrogenpolysiloxane at 30-120° C. and an organic peroxide is concomitantly used. The composition inhibits addition reaction at room temperature, maintains storage stability over a long period, yet can cure rapidly at moderate temperature.
