Abstract
The invention relates to enamels which are water-dilutable after neutralization with bases and which contain non-ionically blocked strong acids as the cross-linking catalysts. In comparison with enamels with ionically blocked strong acids, the hardened enamel films exhibit no wrinkling and improved acid-resistance.
Claims2
Oven-drying coating materials which are water-dilutable after neutralization with bases and are based on combinations of polyhydroxyl-functional addition polymerization resins and/or polycondensation resins and/or polyaddition resins and/or emulsion copolymers which are water-dilutable after neutralization with bases, with amino resins which are at least partially etherified with monoalcohols, characterized in that the coating materials contain as crosslinking catalysts reaction products of strong organic or inorganic acids with mono- and/or diepoxide compounds and/or lactones.
