  • Curable compositions containing cyclic diamine and cured products therefrom
    Patent number: 8980979
    Abstract: A curable composition including (a) at least one cyclic diamine, (b) at least one non-heterocyclic amine that has a pKa value of approximately 9.5 to about 12 at 25° C. for the most basic amine group in the non-heterocyclic amine molecule, (c) at least one epoxy resin, and (d) at least one alkylated phenol; (i) wherein the equivalents of the amine hydrogens from the cyclic diamine compared to the total amine hydrogens from both the cyclic diamine and the non-heterocyclic amine in the composition are greater than about 5%; (ii) wherein the ratio of the equivalents of the total amine hydrogens in the composition to the equivalents of the total epoxies in the composition is greater than or equal to about 1; and (iii) wherein the alkylated phenol is in an amount greater than about 10 wt % of the curable composition.
