Claim:
1. A curable composition, comprising: an epoxy functional component including at least one epoxy functional ingredient having an average of at least 1.5 epoxy moieties per molecule, and an amine functional component including at least one polycyclic polyamine and one or more additional polyamines that are more hydrophobic than the at least one polycyclic polyamine, wherein the at least one polycyclic polyamine comprises the formula wherein: (a) each X is independently a divalent linking group; (b) each Q independently is H, a monovalent moiety, or a co-member of a ring structure with another Q; (c) each Z independently is H or a monovalent moiety optionally incorporating one or more heteroatoms and/or substituents that comprise amine functionality or are substantially inert with respect to amine functionality; with the proviso that one or more of Z and/or Q are selected such that the polycyclic polyamine comprises on average greater than 1.5 active amine moieties per molecule; and (d) R is H, a monovalent moiety optionally incorporating one or more heteroatoms and/or substituents that comprise amine functionality or are substantially inert with respect to amine functionality; or has the formula wherein Y is a single bond or a divalent linking group having the same definition as X, and each Q and Z independently is as defined above.
