Abstract: Two-component epoxy resin compositions are disclosed. The polyepoxide component comprises one or more oligomers having at least one aromatic ring substituent R4X1—in which R4 represents a substituted or unsubstituted aliphatic group having at least 4 carbon atoms, a substituted or unsubstituted cycloaliphatic group having at least 5 carbon atoms, a poly(oxyalkylene) group wherein the average number of carbon atoms per oxyalkylene unit is at least 3, or a aryl group having one or more of the foregoing substituents, bonded directly to the aryl group via a covalent bond or bonded to the aryl group via an oxy, a thio, or a carbonyloxy divalent linking group, or a combination thereof, and X1 represents a covalent bond or a divalent moiety selected from oxy, thio, carbonyloxy, and —X2C(R2)2C(R1)(OH)C(R2)2O—, in which X2 represents a covalent bond or a divalent moiety selected from oxy, thio, and carbonyloxy, R1 represents —H or —C1-14 alkyl, and each R independently represents —H or —CH3.

Abstract: A water-dispersible composition including a nanofiller-containing epoxy resin and a low temperature nonionic surfactant having a molecular weight of less than about 7,000 Daltons; and optionally an anionic surfactant or optionally a high temperature nonionic surfactant. The water-dispersible composition can be used to prepare an aqueous dispersion of the nanofiller-containing epoxy resin. The aqueous dispersion advantageously has a long shelf- stability. One method for preparing the aqueous dispersion includes using a high internal phase ratio emulsion process.
