摘要： The invention relates to a non-aqueous liquid coating composition comprising a) a polyol, b) a polyisocyanate crosslinker c) one or more thiol-functional compounds, d) a metal-based curing catalyst for catalyzing the addition reaction of isocyanate groups and hydroxyl groups, e) a base having a pKa value of at least 7, and which base does not react with isocyanate groups in a way wherein the basicity is reduced, and f) one or more acid group-containing compounds, wherein the one or more thiol-functional compounds are present in an amount to provide a molar ratio of thiol groups over the metal atoms of the metal-based curing catalyst of 1 or higher, and wherein the base is present in a molar amount lower than the molar amount of thiol groups, and wherein the molar ratio of acid groups and base groups is 1:1 or higher.
