THERMALLY-CURABLE HEAT-CONDUCTIVE SILICONE GREASE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a thermally-curable heat-conductive silicone grease composition which has high shape retention characteristics even in an early stage when the viscosity of the composition is low (the composition is easily applied), and which becomes soft (having low hardness) after being cured.SOLUTION: A thermally-curable heat-conductive silicone grease composition includes: (A) an organopolysiloxane having viscosity of 100 to 100,000 mPa s at 25°C and containing at least one alkenyl group per molecule; (B) an organopolysiloxane represented by general formula (1); (C) an organohydrogenpolysiloxane containing at least two hydrogen atoms each directly bound to a silicon atom per molecule; (D) a catalyst selected from a group consisting of platinum and platinum compounds; (F) a heat-conductive filler having heat conductivity of 10 W/m °C or more; and (G) silica fine powder, as essential components.
