Abstract:
An epoxy resin emulsion includes a continuous phase including an aqueous carrier and an acid. The emulsion also includes a dispersed phase including an epoxy resin. The epoxy resin is the reaction product of an amine compound and a first epoxy reactant. The first epoxy reactant itself includes the reaction product of (1) an aromatic diol monomer, (2) a di-glycidyl ether of Bisphenol A and/or a di-glycidyl ether of catechol, and (3) a C8-C18 alkyl phenolic end-capping agent. The (1) aromatic diol monomer has the structure: In this structure, each of R1-R4 is independently a hydrogen atom, a C1-C8 alkyl group, a C3-C8 cycloalkyl group, an aryl group, an aralkyl group, a halide group, a cyano group, a nitro group, a blocked isocyanate group, or a C1-C8 alkyloxy group or wherein any two or more of R1-R4 may be a fused ring.
