Waterborne epoxy color paint was prepared with self-emulsifying curing agent and epoxy resin.The high quality film was obtained by adding different accessory ingredients with different quantum.The effects of pigment volume concentration(PVC),ratios of amine hydrogen and epoxy on paint properties were investigated.It is found that when PVC was 33.3%,the comprehensive properties of coating film are the best.As ratio of amine hydrogen to epoxy increases,the flexibility and water resistance of the film become worse.
