Abstract:
The present invention relates to epoxy coating formulations that comprise an epoxy functional component comprising at least one epoxy functional ingredient comprising an average of at least 1.5 epoxy moieties per molecule; and an amine functional component comprising at least one polycyclic polyamine that comprises (i) a first cyclic structure comprising a first cyclic backbone, a first tertiary amine moiety having a first tertiary nitrogen atom that is a constituent of the first cyclic backbone, at least one additional amine moiety having a nitrogen atom that is a constituent of the first cyclic backbone, and optionally one or more additional amine moieties present in the cyclic backbone and/or in one or more groups pendant from the first cyclic backbone; (ii) a second cyclic structure comprising a second cyclic backbone, a second tertiary amine moiety having a second tertiary nitrogen atom that is a constituent of the second cyclic backbone, at least one additional amine moiety having a nitrogen atom that is a constituent of the second cyclic backbone, and optionally one or more additional amine moieties present in the cyclic backbone and/or in one or more groups pendant from the second cyclic backbone; and (iii) at least one linking group interconnecting the first tertiary nitrogen atom to the second tertiary nitrogen atom; and wherein the polycyclic polyamine has on average greater than one active amine moiety per molecule.
