ABSTRACT:
More than about 9/10 (by weight as a platinum group metal atom) of the necessary amount of a platinum group metal catalyst enclosed in a compound having a melting or softening point of 40-200.degree. C., less than about 1/10 (by weight as a platinum group metal atom) of the necessary amount of a platinum group metal catalyst, and an addition reaction retarder are blended in an organopolysiloxane composition comprising an organopolysiloxane containing alkenyl or hydroxyl radicals and an organohydrogenpolysiloxane. The composition has improved shelf stability, an increased pot life, good curing capability, and fast curing upon heating.
