A process for coating metallic surfaces with an aqueous-containing polymeric composition, the aqueous composition and use of the coated substrates

The invention relates to a process for coating a metallic surface with an aqueous composition, wherein the composition in addition to water a) as a main component an organic film from at least one resin of 70 to 100 wt .-% of the content (of resin s) in the organic film former at least one water-soluble or / and water-dispersed synthetic resin in the form of polymers, copolymers, block copolymers and / or graft copolymers based on synthetic resins selected from the group consisting of polycarbonate, polyurethane, ionomer, poly (meth) acrylate containing polyesters, polyethers and / or polystyrene, wherein the content of polycarbonate and polyurethane is at least 10 wt .-% . b) at least one long chain alcohol as a film-forming aid for the organic film formers, c) at least one crosslinker, d) at least one lubricant, and e) at least one substance on the basis of silane, silanol and / or siloxane and / or at least one inorganic compound in particle form having an average particle diameter, measured by a scanning electron microscope in the range from 0.005 to 0.3 microns in diameter, and f) optionally at least one organic corrosion inhibitor, at least one organic solvent and / or at least one additive, wherein the metallic surface with the aqueous composition is brought into contact and a polymeric film on the metallic ...
