Abstract (en)

[origin: EP0251192A2] The aqueous lubricant for metal cold-forming contains 10 to 35% by weight of a thermosetting acrylate-based resin having a glass transition point of -10 to +25 DEG C, 3 to 15% by weight of wax and 0.5 to 5% by weight of a surfactant, the thermosetting resin/wax weight ratio being adjusted to 2-12. Particularly suitable resins are of the general formula -(Ra-Rb-Rc-Rd)n-, Ra, Rb, Rc and Rd being different monomers and "n" being a degree of polymerisation from 1,000 to 50,000. The wax should have a melting point above 45 DEG C. In the process for faciliting the cold-forming of metallic workpieces, the lubricant is applied to the metal surface, dried on in air to form a coating weight from 0.5 to 30 g/m<2>, heated to a temperature of 80 to 120 DEG C (object temperature) and finally cured.
