Abstract:
1. A process for preparing a metallic workpiece for a cold forming process comprising: applying a lubricant layer either on to a metallic surface or on to a pre-coated metallic surface, wherein the lubricant layer is formed by contacting the metallic or pre-coated metallic surface with an aqueous lubricant composition comprising an ionomer, an organic polymeric material and a waterglass; wherein the organic polymeric material is selected from the group consisting of a monomer, an oligomer, a co-oligomer, a copolymer based on acrylic acid, methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene and urethane, esters thereof and salts thereof, and wherein the lubricant composition or the coating formed therefrom comprises an additional organic polymeric component which is not an ionomer, wherein the additional organic polymeric component is selected from the group consisting of an oligomer, a polymer and a copolymer based on a member selected from the group consisting of acrylic acid, methacrylic acid, an amide, an amine, an aramid, an epoxide, an ethylene, an imide, a polyester, a propylene, a styrene and a urethane and esters and salts thereof.
