Abstract
Official abstract text for this publication.
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 π-electron system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A non-aqueous coating composition consisting essentially of: (a) an aliphatic or cycloaliphatic polyisocyanate, (b) a polyol having an average functionality of more than 3 hydroxyl groups per molecule, wherein the polyol is selected from polyester polyols, polyacrylate polyols, polycarbonate polyols, polyurethane polyols, melamine polyols, and mixtures thereof, (c) a metal based curing catalyst for the addition reaction of isocyanate groups and hyd…
