Abstract
In a heat-curable silicone elastomer composition comprising (A) an organopolysiloxane having at least two aliphatic-unsaturated hydrocarbon groups each bonded to a silicon atom and (B) an organohydrogenpolysiloxane having at least two hydrogen atoms each bonded to a silicon atom, there is blended (C) a hydrosilylating catalyst in the form of a hydrosilylation-promoting compound on a porous filler having a mean particle size of 0.1-100 .mu.m and a pore volume of 0.5-5 cm.sup.3 /g. The composition is stable during storage at room temperature, but quickly curable at elevated temperatures through hydrosilylation reaction.
