1. A one-component coating system comprising
an aqueous polyacrylate polymer dispersion and one or more compounds of elements of sub-groups 5 and/or 6 of the periodic table in which the particular element has an oxidation state of at least +4, wherein the compounds of elements of sub-groups 5 and/or 6 of the periodic table are selected from the group consisting of ammonium molybdate, lithium molybdate, sodium molybdate, potassium molybdate, rubidium molybdate, caesium molybdate, ammonium paramolybdate, molybdenyl-bis-acetylacetonate, molybdenum dioxide tetramethyl heptadionate, molybdenum alcoholates of 1,2-, 1,3- and/or 1,4-diols, molybdenum oxides, tetraethylammonium molybdate and magnesium molybdate, whereby the polyacrylate polymer does not contain any urethane moieties and the coating system does not contain any curing agent selected from the group consisting of ketimine-based curing agents, aliphatic amine curing agents, aromatic amine curing agents, polyamide curing agents, thio-based curing agents, isocyanates, isocyanurates, (co)polymers of isocyanate-functional monomers and blocked isocyanates. |
