Patent ID: 8383005

Claim:
A thermally conductive silicone grease composition comprising: (A) 100 parts by weight of an organopolysiloxane having at least two alkenyl groups in one molecule and having a kinetic viscosity of 5,000 to 100,000 mm 2 /s at 25° C.; (B) 10 to 50 parts by weight of a hydrolyzable methylpolysiloxane having a trifunctional termination at one end and represented by the following general formula (2): wherein R 2 represents an alkyl group having 1 to 6 carbon atoms and b is an integer of 5 to 100; (C) 500 to 1,500 parts by weight of a thermally conductive filler having a thermal conductivity of at least 10 W/m·° C.; (D) an organohydrogenpolysiloxane containing from 2 to 5 hydrogen atoms directly bound to silicon atoms (Si—H groups) in such an amount that the number of Si—H groups/the number of the alkenyl groups of the component (A)=1.7 to 2.8; (E) 0.05 to 0.5 parts by weight of a bonding aid having a triazine ring and at least one alkenyl group in one molecule; and (F) a catalyst selected from the group consisting of platinum and platinum compounds in such an amount of 0.1 to 500 ppm of a platinum atom relative to the component (A).
