| titleOfInvention | Improved method for anti-corrosion pre-treatment of a metal surface containing steel, galvanised steel, aluminium, magnesium and/or a zinc-magnesium alloy |
| abstract | The present invention relates to an improved method for an anti-corrosion pre-treatment of a metal surface containing steel, galvanised steel, aluminum, magnesium and/or a zinc-magnesium alloy, in which method the metal surface is brought into contact with an aqueous composition A that comprises a) 0.01 to 0.5 g/l, (calculated as an addition of a solid), of at least one copolymer which has, in an alternating configuration, i) monomer units containing at least one carboxylic acid group, phosphonic acid group and/or sulfonic acid group, and ii) monomer units with no acid group, and in which method the metal surface is brought into contact with an acidic aqueous composition B that comprises b1 ) at least one compound selected from the group consisting of titanium compounds, zirconium compounds and hafnium compounds. The metal surface is brought into contact i) first with composition A and then with composition B, ii) first with composition B and then with composition A and/or iii) simultaneously with composition A and composition B. The invention also relates to a corresponding aqueous composition A, to an aqueous concentrate for producing this composition, to a correspondingly coated metal surface and to the use of a correspondingly coated metal substrate. |
