Abstract (en)
[origin: WO2022136155A1] The invention relates to a polyaspartic acid ester-containing composition, a two-component coating composition containing said composition, a coating method and use of the coating composition, and a product obtained by applying the coating composition. The polyaspartic acid ester-containing composition comprises a. a Polyaspartic acid ester; b. a thiol with an active hydrogen group; and c. optionally an antioxidant in an amount of not more than 3% by weight, relative to the total weight of the composition; wherein the molar ratio of mercapto groups of the thiol of component b) to amino groups of the polyaspartic acid ester of component a) is of 0.060-0.720. The composition of the present invention has high color stability and is not prone to yellowing.
