Abstract:
1. A method of coating a metallic surface comprising wetting a metallic surface with an aqueous dispersion which comprises water and at least one UV-crosslinkable water-soluble or water-dispersible resin, at least one wax as forming additive, at least one photoinitiator, and at least one corrosion inhibitor, the coating which has formed on the metallic surface being dried and UV cured to form a coated metallic surface, wherein a coating is formed which in cured form has a thickness of up to 10 microns and which on a test surface subjected to forming in a mandrel bending test in accordance with DIN ISO 6860 but without cracking of the test surface with a mandrel of from 3.2 mm to 38mm in diameter produces no signs of corrosion >5% in the course of an immediately following condensation climate test in accordance with DIN 50017 KFW over 240 hours.
