摘要:
A room-temperature-curable organopolysiloxane composition comprising: (A) 100 parts by weight of an organopolysiloxane having a viscosity of from 100 to 500,000 mPa·s at 25° C. and having in one molecule 1.5 or more end groups represented by the general formula: (X)aR13-aSi—, where each X is independently a hydroxyl group or a hydrolyzable group, each R1 is independently a monovalent hydrocarbon group or a halogen-substituted monovalent hydrocarbon group, and a is 1, 2, or 3; (B) 0.01 to 40 parts by weight of a cross-linking agent selected from a silane or a siloxane oligomer where the cross-linking agent has three or more silicon-bonded hydrolyzable groups per molecule; and (C) microparticles of thermoplastic resin containing a platinum compound in such an amount that the content of metallic platinum in component (C) is within the range of 0.01 to 5 wt. %, where the microparticles have an average diameter from 0.1 to 20 μm, component (C) is present in an amount sufficient to provide 1 to 2,000 ppm of metallic platinum in the composition; and (D) 5 to 300 parts by weight of an inorganic powder.
