COATING COMPOSITION COMPRISING A POLYISOCYANATE AND A POLYOL

摘要

The invention relates to a coating composition comprising a) a polyacrylate polyol obtainable 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; b) a polyester polyol obtainable 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, and c) an isocyanate-functional crosslinker.
