Abstract:
1. A heat-conductive silicone grease composition that will increase its viscosity with moisture at room temperature, comprising: (A) 5 to 70 parts by weight of an organopolysiloxane capped with hydroxyl at both ends and having an absolute viscosity of 0.1 to 1,000 Pa-s at 25° C; (B) 30 to 95 parts by weight of an organopolysiloxane having the general formula (1): wherein each R 1 is independently a substituted or unsubstituted monovalent hydrocarbon radical, each R 2 is independently an alkyl, alkoxyalkyl, alkenyl, or acyl radical, n is an integer of 2 to 80, and a is an integer of 1 to 3, the sum of components (A) and (B) being 100 parts by weight; (C) 1 to 30 parts by weight of a silane compound having at least three hydrolyzable radicals bonded to silicon in a molecule, and/or a (partial) hydrolyzate or (partial) hydrolytic condensate thereof; (D) 0.01 to 20 parts by weight of a thickening catalyst; and (E) 100 to 2,000 parts by weight of a heat-conductive filler having a heat conductivity of at least 10 W/m° C.
