Abstract
Abstract A solid lubricating and coating composition for metal working which composition is suitable for the addition to water for the formation of an aqueous lubricating and coating composition which aqueous composition when dried will form a hard lubricating film on a substrate, such that film will provide lubricity but residues of film will not buildup on metal working tools and dies. The solid composition includes a solid alkali metal salt of a saturated monocarboxylic acid having from about 12 to 30 carbon atoms; polyethylene glycol or a polyoxyethylene glycol having a molecular weight in the range of from about 1500 to about 8000; an acrylic polymer and an effective amount of a surface active agents to effect low hygroscopicity and complete mixing of the ingredients in water.
