Abstract:
A liquid composition suitable for applying to metal substrates a lubricating layer for cold working the metal substrates after drying the liquid composition on the metal substrates, said liquid composition comprising water and the following dissolved, dispersed, or both dissolved and dispersed components:(A) a component of ethoxylated straight chain aliphatic alcohol molecules, wherein the ethoxylated straight chain aliphatic alcohol molecules are produced by condensing ethylene oxide with aliphatic monoalcohols that have a single â€”OH moiety and at least 18 carbon atoms per molecule; (B) a component selected from the group consisting of lithium salts, sodium salts, and calcium salts, all of said salts being salts of fatty organic acids, wherein: component (A) is selected from ethoxylated straight chain aliphatic alcohol molecules in which: oxyethylene moieties constitute from about 20 to about 80% of the total mass of the ethoxylated alcohol molecules; in component (B), there is an average number of from about 14 to about 26 carbon atoms per molecule of salt; there is also present a dissolved component (C) that is selected from the group consisting of metaboric acid, orthoboric acid, and alkali metal and ammonium salts of metaboric and orthoboric acids and of tetraboric acid; and there is also present a dissolved, dispersed, or both dissolved and dispersed component (D) that is selected from the group consisting of condensation products of ethylene oxide, propylene oxide, or both ethylene and propylene oxides with triglycerides of fatty acids that include moieties condensable with ethylene oxide and/or propylene oxide.
