Title: HOT MELT METAL WORKING LUBRICANTS Inventor: Richard William Jahnke Abstract of the Disclosure: Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30-100°C. The composition comprises at least one neutral ester, and preferably a mixture of esters, prepared from polyalkylene glycols and saturated aliphatic alcohols having at least about 10 carbon atoms, and C12-25 aliphatic monocarboxylic acids and C4-20 aliphatic polycarboxylic acids. The preferred ester mixtures are prepared from poly- ethylene glycols, C14 -20 predominantly straight chain alkanols, stearic acid and adipic, azelaic or sebacic acid. Optional ingredients include phosphorus acid salts and anti- oxidants. The composition may be applied in liquid form and solidifies on cooling to normal ambient and storage temperatures.
