Heat-curable silicone elastomer composition

Abstract

Abstract PURPOSE:To provide the title composition with excellent storage stability and high-temperature rapid curability without impairing the heat resistance by mixing a specified organopolysiloxane, a specified organohydrogenpolysiloxane, a particulate silicone resin containing a hydrosilylation catalyst, and a hydrosilylation inhibitive compound. CONSTITUTION:A composition made by mixing an organopolysiloxane having at least two alkenyl groups in the molecule; an organohydrogenpolysiloxane having at least two hydrogen atoms attached to a silicon atom in the molecule; a particulate material which consists of a hydrosilylation catalyst and a silicone resin having a softening point or glass transition point of 40-200 deg.C, has a mean particle diameter of 0.01-10mum, with particles of above 10mum in diameter accounting for at most 5wt.%, and does not substantially contain a surface active agent; and a hydrosilylation inhibitive compound.
