Abstract: A dry Non-Oil metalworking lubricant that can be applied by a hot melt application. This dry lubricant is completely water soluble, provides rust protection, cleans from surfaces with plain room temperature water, and is more environmentally safe than other lubricants. A polyethylene glycol of sufficiently high molecular weight to be solid at room temperature is combined with amines, rust inhibitors, and metalworking additives to produce a thin film that provides protection for the part and the tooling in a metalworking operation. This lubricant provides further benefits to the overall process such as; easy to clean, weld through capability, excellent paint system compatibility, and environmentally superior to other lubricants.
