Abstract: The present invention relates to a grease composition for use in harnesses, which comprises a thickening agent, a base oil and additives, wherein the base oil comprises a polyoxyalkylene glycol ether and the additives comprise a quinoline compound and a benzotriazole compound. The grease composition is quite excellent in the corrosion resistance, the oxidation stability and the compatibility with materials such as olefinic elastomer.

Abstract: A lubricant composition comprising from 0.1 to 10% by weight of a phosphate glass, characterized in that said phosphate glass comprises from 45 to 75 mole % of P.sub.2 O.sub.5, from 10 to 35 mole % of M.sub.2 O (M represents alkaline metals) and from 0 to 45 mole % of B.sub.2 O.sub.3. Phosphate glasses are in the form of powder with white to ash-colored appearance, and do not cause dirt of working surroundings. Phosphate glasses are less expensive than solid lubricants which are conventionally used, and also excellent load carrying capacity can be attained by adding a small amount of phosphate glass to a lubricant composition. Accordingly, the lubricant composition of the present invention shows better load carrying capacity than a conventional lubricant composition.

Abstract: A lubricating composition comprises a lubricating grease and a heat-curable resin selected from the group consisting of urea resins, malamine-formaldehyde resins, epoxy resins, furan resins, xylene resins, silicone resins and urethane resins. The lubricating composition permits the solution of the problem of scattering and/or sags and runs thereof from portions to be lubricated, can be molded into a variety of shapes and can show a sealing function by itself. The lubricating composition can serve not only as a lubricant, but also as a rust preventing and a coating agent.
