摘要：The present invention relates to epoxy coating formulations that comprise anepoxy functional component comprising at least one epoxy functional ingredientcomprising an average of at least 1.5 epoxy moieties per molecule; and an aminefunctional component comprising at least one polycyclic polyamine that comprises (i) afirst cyclic structure comprising a first cyclic backbone, a first tertiary amine moiety havinga first tertiary nitrogen atom that is a constituent of the first cyclic backbone, at least oneadditional amine moiety having a nitrogen atom that is a constituent of the first cyclicbackbone, and optionally one or more additional amine moieties present in the cyclicbackbone and/or in one or more groups pendant from the first cyclic backbone; (ii) asecond cyclic structure comprising a second cyclic backbone, a second tertiary aminemoiety having a second tertiary nitrogen atom that is a constituent of the second cyclicbackbone, 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 aminemoieties present in the cyclic backbone and/or in one or more groups pendant from thesecond cyclic backbone; and (iii) at least one linking group interconnecting the first

tertiary nitrogen atom to the second tertiary nitrogen atom; and wherein the polycyclicpolyamine has on average greater than one active amine moiety per molecule.
