ABSTRACT:
A coating composition comprising a binder ofa. polyisocyanate crosslinking agent;b. an isocyanate-reactive component having at least one compound having the following formula:wherein n on average is 1.7 to 2 and X stands for a cycloaliphatic norbornane derivative containing methylene amine groups of formula (II)either alone, as combinations of these, and/or as mixtures of isomers of these, in which the exact point of attachment and orientation of —CH2— group to the NH group and R20—R22to the norbornane scaffold can vary and mixtures of compounds and isomers are commonly utilized by this invention; two component compositions and articles coated with the novel composition also are part of the invention.
