Abstract (en)
[origin: WO9808922A1] A waterborne lubricant for the cold plastic working of metals that contains alkali metal salts of dimer(s) and/or trimer(s) of unsaturated fatty acids with from 10 to 24 carbon atoms per molecule has a lubrication performance at least as good as that of prior lubricants, even at generally lower lubricating film weights, has a long bath life, and generates little dust during cold plastic working operations. Even as little as 5 % of these salts of dimer(s) and/or trimer(s) of unsaturated fatty acids, when mixed with conventional alkali metal salts of saturated fatty acids with from 10-24 carbon atoms per molecule, can provide these benefits.
