(A) an organopolysiloxane having a kinematic viscosity of 5,000 to 100,000 mm 2 / s at 25 ° C having at least two alkenyl groups in one molecule, (B) the following general formula (2) (R 2 is an alkyl group having 1 to 6 carbon atoms, b is an integer of 5 to 100.) Single-terminal trifunctional hydrolyzable methylpolysiloxane, represented by (C) a thermally conductive filler having a thermal conductivity of 10 W / m? (D) organohydrogenpolysiloxane containing a hydrogen atom (Si-H group) directly connected to 2 or more and 5 or less silicon atoms in 1 molecule, (E) Adhesion aids having a triazine ring and at least one alkenyl group in one molecule, (F) a catalyst selected from the group consisting of platinum and platinum compounds A thermally conductive silicone grease composition comprising a. In the thermally conductive silicone grease composition of the present invention, the increase in hardness at the time of high temperature heating is small, and the decrease in elongation is suppressed. |
