摘要
the invention relates to aqueous coating agent compositions containing at least one type of organic polymer particles having an average particle size of 10 to 1,000 nm, comprising isocyanate-reactive polymers (a), one or more polyisocyanates blocked with ketoxime and / or pyrazole (b), which contain at least a fraction of aromatic hydrocarbon or at least a fraction of cycloaliphatic hydrocarbon, at least one polyanionic polymer (c), at least one complex fluoride (d) selected from the group consisting of hexa- or tetrafluorides of the metallic elements of the groups ivb, vb and vib of the periodic table of the elements, and at least one aminosilane (e), the aqueous coating agent compositions having a ph value of 3 and comprising a total solid content from 5% to 35% by weight. the invention further relates to a method for producing said coating agent compositions, a method for coating surfaces that releases metal ions with coating agent compositions according to the invention, and coatings obtained therefrom.
