A home-made waterborne epoxy resin curing agent was used to cure the home-made E-type non-ionic waterborne epoxy resin latex at room temperature. The curing effect and the performance of the coatings film were investigated. Its curing mechanism was explored and a curing model was proposed to guide the design of structure of curing agent . Particle size analysis,laser confocal microscopy(LSCM), transmission electronic microscopy(TEM), scanning electronic microscopy(SEM),atomic force microscopy(AFM)were used to characterize the curing process and explore the curing mechanism. Further,three models of curing process were proposed. The results showed that the home-made curing agent and the latex were mixed for a period of time,and then merged with each other,and the boundary of the latex particles becomes blurred. The surface structure of the coatings film was uniform and the cross-section compatibility was good,indicating that the curing process was completed.
