COMPOSITION AND PROCESS FOR LUBRICATED PLASTIC WORCOMPOSITION AND PROCESS FOR LUBRICATED PLASTIC WORKING OF METALS KING OF METALS

摘要

A lubricant composition for the plastic working of metals that does not require a phosphate undercoating, is waterborne, requires only a simple application process of immersion or spraying followed by drying, and provide s an excellent lubricating performance comprises synthetic resin, water-solubl e inorganic salt, and water. The weight ratio of the content of salt to that o f synthetic resin is from 0.25:1 to 9:1. This composition can also contain liquid and/or solid lubricating agent(s) and extreme pressure additive.
