Claim Text:
1. A heat-conductive silicone grease composition adapted to thicken with moisture at room temperature, comprising as essential components, (A) 5 to 50 parts by weight of an organopolysiloxane capped at both ends with a hydroxyl group and having a viscosity of 0.1 to 1,000 Pa·s at 25° C., (B) 50 to 95 parts by weight of an organopolysiloxane represented by the general formula (1): wherein R R n is an integer of 2 to 80, and a is an integer of 1 to 3, (C) 1 to 30 parts by weight of a silane compound containing at least three silicon-bonded hydrolysable groups per molecule and/or a (partial) hydrolyzate or (partial) hydrolytic condensate thereof, (D) 0.01 to 20 parts by weight of a thickening catalyst in the form of a silane or siloxane containing a guanidyl group, (E) 100 to 2,000 parts by weight of a heat conductive filler having a thermal conductivity of at least 10 W/m·° C., and (F) silica fine powder in an amount of 10 to 100 parts by weight per 100 parts by weight of component (A).
