摘要:
The present invention relates to a coating composition for the preparation of a polyurea coating which containsa) a polyisocyanate component containing one or more aliphatic polyisocyanates,b) at least one polaspartic acid esterc) 0.05 to 5% by weight, based on the total weight of the coating composition, of an organic acid,wherein components a) and b) are present in amounts sufficient to provide an equivalent ratio of isocyanate groups of component a) to isocyanate-reactive groups of component b) of 0.5:1 to 20:1.
