The aqueous lubricant preferably further comprises (C) a metal salt of a fatty acid in a solid concentration ratio (C) /(A) of 0.01 SIMILAR 0.4. The water soluble inorganic salt (A) is preferably selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax is preferably a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The metal salt of a fatty acid (C) is preferably obtained through reacting a saturated fatty acid having 12 SIMILAR 26 carbon atoms with a metal selected from among zinc, calcium, barium, aluminium, magnesium and lithium. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of metal having no chemical conversion layer formed thereon.

Abstract:
The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The treated agglomerates are then blended or clad with a metal, metal alloy or a metallic composition, to produce a composition suitable for thermal spray applications.

Abstract:
A process for manufacturing a lubricant composition comprises combining a superabsorbent polymer with a material for decreasing friction between surfaces that frictionally engage one another, by polymerizing monomers of the superabsorbent polymer with the material for decreasing friction, or polymerizing the monomers for forming the superabsorbent polymer with the material for decreasing friction and a binder, where the binder is selected from thermoplastic resins or curable resins. The superabsorbent polymer may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. The material for decreasing friction comprises a petroleum lubricant, synthetic lubricant, grease, solid lubricant or metal working lubricant optionally containing a lubricant additive, or mixtures thereof. The process encompasses conducting the polymerization and coating the lubricant composition on a surface such as a wire or cable. The various processes also yield products produced by the process.
