摘要： A heat-conductive silicone grease composition is provided comprising (A) a trialkoxysilyl-endcapped organopolysiloxane having a viscosity of 0.1-1,000 Pa·s at 25° C., (B) a specific organopolysiloxane, (C) a heat-conductive filler, and (D) a condensation catalyst. The composition is amenable to coat at the initial, thereafter increases its viscosity with moisture at room temperature rather than curing so that it remains flexible, easy to re-work, and anti-sagging, eliminates a need for cold storage and for hot application, avoids any undesired viscosity buildup, is easy to manufacture, and has good heat transfer.

摘要： Provided is a heat-conductive silicone composition, including: (A) 100 parts by volume of an organopolysiloxane having a specific structure, (B) 0.1 to 50 parts by volume of an organosilicon compound that functions as a wetter and contains a triorganooxysilyl group bonded to one terminal via an alkylene group that may be branched, (C) 100 to 2,500 parts by volume of a heat-conductive filler, and (D) an effective quantity of a curing agent. Also provided is a heat-conductive silicone cured product obtained by curing this composition.

The heat-conductive silicone cured product exhibits excellent flexibility even when filled with a large quantity of a heat-conductive filler. Heat generated by a heat-generating electronic component can be dissipated into a heat-radiating component by sandwiching the cured product between the heat-generating electronic component and the heat-radiating component.
