    Abstract: Provided is a heat conductive silicone grease composition including (A) 100 parts by mass of an organopolysiloxane containing 2 or more alkenyl groups bonded to silicon atoms within each molecule, (B) an organohydrogenpolysiloxane containing 2 or more hydrogen atoms bonded to silicon atoms within each molecule, in sufficient quantity to provide from 0.1 to 5.0 hydrogen atoms bonded to silicon atoms within the component (B) for each alkenyl group within the component (A), (C) 100 to 2,200 parts by mass of a heat conductive filler, (D) an effective quantity of a platinum-based catalyst, and (E) an effective quantity of an addition reaction retarder, in which the component (C) includes more than 90% by mass and no more than 100% by mass of an indium powder with an average particle size of 0.1 to 100 µm. Also provided is a heat conductive silicone cured product obtained by curing the above composition by heating at a temperature equal to, or greater than, the melting point of the indium powder. Further provided is an electronic device including an electronic component, a heat radiating member, and a heat conductive member including the above cured product disposed between the electronic component and the heat radiating member. Still further provided is a method of curing the above composition. Even further provided is a method of forming a heat conductive member between an electronic component and a heat radiating member. The above heat conductive silicone grease composition generates a suitably thin cured product with excellent thermal conductivity that prevents problems such as the contamination of components other than the coated component, and the leakage of oily materials from the product if used over extended periods.

    Abstract: PROBLEM TO BE SOLVED: To provide a film composition for a sliding member capable of forming a film capable of keeping good lubricity even in a state exposed in a severe friction condition for a long time.
    SOLUTION: The film composition for the sliding member for forming the film on the surface of the sliding member contains a binder resin, an abrasion-inhibiting material and a solid lubricant. The abrasion-inhibiting material is in a form of plate having an aspect ratio expressed with an average particle size/average particle thickness of 5-100, and the average particle size is ≤15.0 μm and Mohs hardness is ≥6. A content of the solid lubricant is 0-15 pts.wt. to the binder resin of 100 pts.wt. A content of the abrasion-inhibiting material is 1-100 pts.wt. to the binder resin of 100 pts.wt. The solid lubricant may be not compounded. The abrasion-inhibiting material is aluminas preferably.
