The invention relates to a non-aqueous coating composition comprising

Coating composition comprising a polyisocyanate and a polyol

The invention relates to a non-aqueous coating composition comprising a. a polyisocyanate, b. a polyol having an average functionality of more than 3 hydroxyl groups per molecule, c. a metal based curing catalyst for the addition reaction of isocyanate groups and hydroxyl groups, and d. a mercapto carboxylic acid, wherein the coating composition does not contain a carboxylic acid wherein the carbonyl group of the carboxylic acid is in conjugation with &#x3c0;-electron system.

The invention relates to a water borne coating composition comprising a) a polyol, b) a polyisocyanate crosslinker, and c) a thiol functional compound, wherein the molar ratio of isocyanate groups to thiol groups ranges between 1:0.0001 and 1:0.4. The invention further relates to the use of the coating composition, and to a kit of parts for preparation of the coating composition. The coating composition according to the invention displays a balance of high curing rate, long pot life, and good film appearance of the coating prepared from it.
