LUBRIFIANT POUR LA FORMATION SANS TAILLAGE DES METAUX AUX TEMPERATURES ELEVEES

摘要

Lubricant is preferably applied in an aqueous dispersion. To prevent coagulation of the solids in the aqueous dispersion on the one hand and to obtain a heat-resistant uniform lubricating film on the other hand, the high-temperature lubricant additionally contains, apart from a solid lubricant, an organic product which decomposes without residue, an inorganic additive of polyphosphate, a boron compound and an alkali metal silicate, and also an organic stabiliser.
