Aqueous acidic lubricant composition and method for coating metals

摘要: A composition and a method for applying lubricant coating to clean metal surfaces prior subjecting them forming operations. The comprises concentrate which is adapted be diluted with water, if desired, produce an aqueous acidic operating bath containing controlled effective amount of phosphate ions form on the surface in combination emulsified organic agent, emulsifying agent soluble corrosion inhibiting agent. may further optionally contain heavy cations activating bath. applied such as by flooding, immersion, spraying, or like, at temperatures from ambient up about 200° F. period time sufficient effect desired magnitude whereafter parts are dried, preferably elevated before forming.
