Abstract: Compositions, methods, and coating composition using a curing agent are provided herein. In one embodiment, a curing agent for epoxy resins may be prepared using a formulation including: (a) an adduct of: (i) a diglycidyl ether of a bisphenol, and (ii) a first polyamine; (b) a second polyamine; and (c) water; wherein the composition has an amine hydrogen equivalent weight, based on solids, of less than or equal to 105.

Abstract: An epoxy oligomerization catalyst can be employed to prepare an epoxy resin employing a method including admixing a first epoxy resin having a first epoxy equivalent weight of from about 100 to about 600 with a diphenolic compound, and a catalyst, thereby forming a second epoxy resin having a second epoxy equivalent weight of from about 200 to about 10,000; wherein the catalyst is a guanidinium catalyst. The second equivalent weight is greater than the first equivalent weight.
