Abstract:
At least one kind of coating modifier selected from polyamidimide resin, epoxysilane and epoxy resin, and at least one kind of hard particles selected from silicon nitride and alumina are impregnated into a dry coating lubricant. The coating layer of a dry coating lubricant is formed on the sliding surface of the base material of a sliding member, with the surface roughness of this coating layer set to up to 3 μmRz in a ten point height of irregularities. The coating layer of a dry coating lubricant is formed on the sliding surface of the base material of a sliding member, the coating layer being formed in a film thickness of at least 10 μm on at least part of the sliding surface of the base material.

Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.

Abstract:
Low bleed silicone grease compositions are prepared by blending high viscosity silicone oils with filler materials and/or silicone elastomers. Greases comprise three main types: I) grease comprising high viscosity silicone oil and filler material, II) grease comprising high viscosity silicone oil and silicone elastomer, and III) grease comprising high molecular weight silicone oil and filler material and silicone elastomer.
Abstract:
A water-based release agent comprises: 30-99 % total solids by weight chemically exfoliated vermiculite, and 1-70 % total solids by weight of a plate-like filler. Such release agents are particularly suitable for use with gaskets. An anisotropic release agent is formed from which it is easy to release other materials.
