摘要： The present invention relates to a process for producing single-coat or multicoat clearcoat finishes on primed or unprimed substrates by applying at least one powder coating dispersion, in particular a powder clearcoat slurry, to the substrate and then curing the resulting film(s) thermally and/or with actinic radiation, in which at least one polyvalent inorganic acid and/or oxalic acid are or is added to at least one powder coating dispersion, in particular to a powder clearcoat slurry.

摘要翻译： 本发明涉及通过将至少一种粉末涂料分散体，特别是粉末透明涂料浆料施加到基材上然后将所得膜热固化，从而在底漆或未涂布基材上生产单涂层或多色透明涂层的方法 和/或光化辐射，其中至少一种多价无机酸和/或草酸被添加至至少一种粉末涂料分散体，特别是粉末涂料浆料中。
