process for coating metal surfaces with a lubricating composition. The present invention relates to a process for preparing metal blanks for cold forming by applying a layer of lubricant either on a metal surface or on a metal surface previously coated, for example with a coating. conversion method, in which the lubricating layer is formed by contacting the surface with an aqueous lubricating composition, which contains a content of at least one water-soluble, aqueous or/and water-linkable oxide or/and silicate, as well as a content of polymeric material organic and being used as organic polymeric material mainly monomers, oligomers, co-oligomers, polymers or/and copolymers based on ionomer, acrylic acid/methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene, urethane, their esters or /and its salt(s). the present invention also relates to the corresponding lubricating composition, the lubricating layer formed therefrom and its use. |
