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.
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant oil composition exhibiting extremely low friction coefficient when used as a lubricant oil for a low friction sliding material; to provide a sliding mechanism with excellent low friction by combining sliding members having a particular coating film for a low friction sliding material on the sliding surface using the same. SOLUTION: The lubricant oil composition used for a low friction sliding material is obtained by compounding an additive selected from a particular phosphorus-zinc-containing compound and a particular sulfur-containing compound. The sliding mechanism includes two mutually sliding members with the lubricant oil composition interposed between their sliding surfaces; wherein at least one of the two sliding members has a DLC (Diamond-Like Carbon) coating film formed on its sliding surface, the DLC coating film containing 5-50 atom% of hydrogen.

Abstract:
A composition comprising (a) fine spherical particles of an inorganic substance such as alumina, (b) an aqueous adhesive agent such as a petroleum resin emulsion, and water. It is preferred for better effect that the composition further comprises one or more selected from among (c) a wisker, (d) a powder of an inorganic substance in a form of a scaly crystal, (e) a powder of a metal hydroxide or an inorganic substance having bound water, and (f) a lubricant aid. The composition is free from problems of the occurrence of environmental pollution and the risk of misoperation of an automatic machine, which accompany a conventional graphite lubricating and releasing agent, and that of the danger of smoking or firing, which accompanies a conventional lubricating and releasing agent dispersed in an oil, and is useful as an aqueous lubricating and releasing agent for hot or cold forging using a non-graphite inorganic substance, which is free from occurrence of the deposition on a mold and an under fill phenomenon.
