Patent ID: 8915108

Claim:
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 a non-ionomer; a wax; 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.
