1. A coating composition comprising:
a) a chain-extended aspartate prepolymer, wherein the chain-extended aspartate prepolymer
x) is free of isocyanate groups,xi) has an NH equivalent weight of from 250 to 1,000 g, andxii) is a reaction product of
i) a mixture comprising at least one di-aspartic acid ester and at least one amino-functional mono-aspartic acid ester, wherein the molar ratio between the at least one di-aspartic acid ester and the at least one amino-functional mono-aspartic acid ester is from 99.5:0.5 to 50:50, andii) at least one cycloaliphatic polyisocyanate, and b) at least one curing agent having free isocyanate groups. |
