摘要

The present invention relates to a process for the production of single- or multi-layer clearcoat coatings on a primed or unprimed substrate by applying at least one powder coating dispersion, in particular a powder clearcoat slurry, to this substrate and subsequent thermal curing and / or curing with actinic radiation of the resulting Layer (s), at least one polyvalent organic acid and / or oxalic acid being added to at least one powder coating dispersion, in particular a powder clear coating slurry.
