Also provided is a heat conductive silicone cured product obtained by curing the above composition by heating at a temperature equal to, or greater than, the melting point of the indium powder. Further provided is an electronic device including an electronic component, a heat radiating member, and a heat conductive member including the above cured product disposed between the electronic component and the heat radiating member. Still further provided is a method of curing the above composition. Even further provided is a method of forming a heat conductive member between an electronic component and a heat radiating member. The above heat conductive silicone grease composition generates a suitably thin cured product with excellent thermal conductivity that prevents problems such as the contamination of components other than the coated component, and the leakage of oily materials from the product if used over extended periods.

    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 composition, even when filled with a large quantity of a heat-conductive filler in order to provide superior thermal conductivity, exhibits a minimal increase in viscosity or plasticity, and retains favorable handling properties and moldability. 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.
