Provided is a room temperature and humidity thickening thermo-conductive silicone grease composition with high shape retention characteristics and good workability despite a low viscosity in an initial phase. Essential components of the room temperature and humidity thickening thermo-conductive silicone grease composition of the present invention are: (A) organopolysiloxane with a viscosity of between 0.1Pa°s and 1,000Pa°s at 25°C with both ends being blocked by a hydroxyl group; (B) organopolysiloxane represented by general equation (1) (1) (R1 is independently a substituted or non-substituted monovalent hydrocarbon group, R2 is independently an alkyl group, alkoxy alkyl group, alkenyl group, or acyl group, n is an integer between 2 and 100, and a is an integer between 1 and 3); (C) a silane compound which contains at least three hydrolysable groups bonded to a silicon atom in one molecule and/or a (partial) hydrolyzate or a (partial) hydrolysis condensate thereof; (D) a thickening catalyst; (E) a thermally conductive filler with a thermal conductivity of at least 10W/m°°C; and (F) silica fine powder. |
