Abstract:
The present invention provides a grease composition which is excellent in peel resistance, not to mention lubricity, as compared with the prior art products. A novel grease composition for rolling bearing is provided, comprising a base oil, an extender, an inorganic compound-based filler having an average particle diameter of not more than 2 &mgr;m and zinc dithiocarbamate.
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:
Encapsulating particles of solid thiocarbonate salts, esters and complexes with air- and water-impermiable coatings produces compositions having long-term stability.
Abstract:
A silicone grease composition comprising:(A) 100 parts by weight of a polyorganosiloxane containing at least two silicon-bonded vinyl groups per molecule and having a viscosity at 25.degree. C. of from 10 to 1,000,000 cSt;(B) from 10 to 200 parts by weight of a filler comprising at least one member selected from the group consisting of calcium carbonate, zinc carbonate, a composite zinc white, and silica; and(C) from 0.001 to 0.1 part by weight of platinum or a platinum compound.
Abstract:
A lubricant composition which is suitable as a fluorine oil, fluorine grease, and which is excellent in stabilizability, as well as a lubricant composition which is suitable as a fluorine oil, fluorine grease, and which has excellent rust prevention properties while keeping a heat resistance.

Abstract:
The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.
Abstract:
An article including a first release liner with a first release surface, a second release liner with a second release surface, and a layer of a thermally conductive grease between the first and the second release surfaces. The thermally conductive grease includes a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5.
Abstract:
The invention provides a grease composition comprising a base oil consisting of a fluorinated oil and an antirust agent, wherein said antirust agent comprises an aliphatic dibasic acid salt of the formula (1) in an amount of not less than 0.1% by mass and less than 1.0% by mass based on the total mass of the grease composition; (CH2)n(COO)2Mm (1) wherein n is an integer of 1 to 19, M is an alkali or alkaline earth metal, m is 2 when M is an alkali metal and m is 1 when M is an alkaline earth metal, and a bearing wherein the grease is packed. The grease exerts less effects on the environment. It is low in evaporation loss at a high temperature, shows good antirust property and can be suitably used in a ball bearing operated at a high temperature.
