Title: REDUCED DUST LUBRICANT AND PROCESS FOR PREPARATION OF METALS FOR COLD FORMING
Abstract:
Release of dust into the environment when using conventional stearate soap lubrication for cold working of metals over a phosphate conversion coating can be greatly reduced by adding to a conventional stearate soap lubricating solution an effective amount, e.g., up to 25 weight percent of a water-soluble alkali metal soap of an unsaturated fatty acid, i.e. oleic acid. Optionally, a film forming polymer to further reduce any dust, along with optional corrosion inhibitors and/or complexing agents for heavy metals.
