Abstract:
1. A coating composition comprising a) a polyacrylate polyol obtained by polymerization of olefinically unsaturated monomers wherein at least 40 weight-% of the monomers comprises linear or branched alk(en)yl or alk(en)ylene groups having at least 4 carbon atoms, wherein the number average molecular weight (Mn) of the polyacrylate polyol does not exceed 5,000, and the polydispersity (Mw/Mn) is below 2.8; b) a polyester polyol obtained by esterification of building blocks having ester-forming functional groups wherein at least 30 weight-% of the building blocks comprises linear or branched alk(en)yl or alk(en)ylene groups with at least 4 carbon atoms per ester-forming functional group, the polyester polyol having a hydroxy value above 280 mg KOH/g and a hydroxy functionality of at least 2, c) an isocyanate-functional crosslinker, and d) a volatile organic diluent, wherein at least 60 weight-% of the volatile organic diluent comprises alk(en)yl or alk(en)ylene groups having at least 4 carbon atoms, wherein the non-volatile content of the coating composition is higher than 50 weight-% based on the total composition.
