Summary: | The use of an aqueous dispersion of a polyol component, comprising 20-60 wt.% unsaturated polyester polyol and 40-80 wt.% polyacrylate, and 1-70 wt.% (with respect to total solids) of a blocked aliphatic polyisocyanate component for light-stable, elastic, physically fast-drying coatings in series lacquering of cars is claimed. The use of an aqueous dispersion of (A) a polyol component and (B) a polyisocyanate component for light-stable, elastic, physically fast-drying coatings in series lacquering of cars is claimed. The polyol component comprises 20-60 wt.% polyester component (AI) with 10-60 wt.% units derived from 8-30 carbon (C) aliphatic (un)saturated monocarboxylic acid(s) and 0.4-5 wt.% units derived from 3-8 C alpha , beta -unsaturated mono- or dicarboxylic acid(s) or anhydride(s) capable of free radical polymerization and 40-80 wt.% polyacrylate component (AII). The polyisocyanate component (B) comprises blocked aliphatic polyisocyanate(s) and is used in an amount of 1-70 wt.% with respect to total solids in the dispersion. |
