Abstract: A novel waterborne epoxy curing agent was prepared by n-butyl acrylate, triethylene tetramine (TETA) and liquid epoxy resin E-51 as a termination agent of the adduct. The results showed that when the reaction temperature was 70 ℃ for 3 h and the molar ratio of adduct to epoxy was 2: 1, the curing agent could provide excellent properties. The film showed good properties such as hardness, adhesion, leveling, gloss.
