Title:
METHOD FOR COATING METALLIC SURFACES AND USE OF SUBSTRATES COATED IN SUCH A WAY OR COATINGS PRODUCED IN SUCH A WAY
Document Type and Number:
WIPO Patent Application WO2002024820
Kind Code:
A3
Abstract:
The invention relates to a method for coating metallic surfaces by wetting one such surface with an aqueous dispersion containing, in addition to water, at least one UV-cross-linkable, water-soluble and/or water-dispersible resin, at least one wax as a deforming additive, at least one photoinitiator and at least one corrosion inhibitor. The coating is dried and hardened after being formed on the metallic surface. The invention is characterised in that the coating that is formed is up to 10 mu m thick when hard, and in that during a condensation water test according to DIN 50017 KFW carried out directly after over 240 hours, said coating shows no signs of corrosion > 5 % on a test surface having been deformed by a mandrel with a diameter of 3.2 mm to 38 mm during a mandrel bending test according to DIN ISO 6860 without cracking the test surface.
