Abstract

Procedure for the pretreatment of moldable metal materials, characterized in that it comprises the treatment of the surface of said materials and their coverage with a removable layer of a water-soluble, film-forming organic polymer, which, if necessary, contains water-soluble polymers with molecular weights of up to 2,000, followed by molding and providing a protective layer with firm adhesion.
