Thermally Conductive Silicone Grease Composition

Abstract

A thermally conductive silicone grease composition comprises: (A) an organopolysiloxane represented by the following general formula: wherein each R1 is independently selected from monovalent hydrocarbon groups, each X is independently selected from monovalent hydrocarbon groups or alkoxysilyl-containing groups of the following general formula: —R2—SiR1a(OR3)(3-a) wherein R1 is defined as above, R2 is an oxygen atom or an alkylene group, R3 is an alkyl group, a is an integer ranging from 0 to 2, m is an integer equal to or greater than 0, and n is an integer equal to or greater than 0; (B) a thermally conductive filler; and (C) an aluminum-based or titanium-based coupling agent. The composition exhibits excellent heat resistance and reduced oil bleeding.
