ABSTRACT:
A room-temperature-curable organopolysiloxane composition comprising:(A) an organopolysiloxane having 1.5 or more end groups having at least one hydroxyl group on the average;(B) a silane or a siloxane oligomer having three or more silicon-bonded hydrolyzable groups;(D) an inorganic powder; and either(C) microparticles of thermoplastic resin containing a platinum compound having an average diameter from 0.1 to 20 μm; or(C1) a platinum compound; and(C2) an organosiloxane oligomer which contains aryl and alkenyl groups and has 8 or less silicon atoms in each molecule and which contains in each molecule at least one divalent organosiloxane as represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?—(R2)(R3)SiO—(R2)(R3)Si—,in-line-formulae description="In-line Formulae" end="tail"?(where R2is an aryl group, and R3is an alkenyl group), in a quantity of at least 2 moles of component (C2) per 1 mole platinum atoms in component (C1).
