The fluorinated epoxy acrylic cathodic electrodeposition (CED) coatings were prepared by mixing blocked polyisocyanate and cationic resin. The cationic resin was prepared via copolymerizing hexafluorobutyl acrylate (HFBA), methyl methacrylate (MMA), butyl acrylate (BA) and glycidyl methacrylate (GMA) and opening loop and acidizing the prepared terpolymer. The particle size of resultant cathodic electrodeposition coatings water suspension was 28.62 nm. Zeta potential of cathodic electrodeposition coatings was 41.84 mV, which indicated the stability of cathodic electrodeposition coating water suspension is high. The water-resistance and chemical resistance of cathodic electrodeposition coatings are improved.

Cathodic electrodeposition (CED) coating has been developed a new type of industrial application of anti-corrosion coating. It has many merits such as little environmental pollution, no fire hazard, excellent corrosion resistance, high throwing power and degree of automation for coating. However, the curing conditions for conventional cathodic electrodeposition coating are that the cathodic electrodeposition coating is cured with the high temperature. The high temperature for curing is not helpful for the auto parts with plastic and rubber, which is easy to deform under such high temperature. Thus, the high temperature for curing is not beneficial to save energy. Therefore, it is essential to develop a novel cathodic electrodeposition coating, which is cured with low temperature. The pathways of decreasing the cured temperature of cathodic electrodeposition coating are reviewed. Furthermore, the practical questions to be solved to promote the development of cathodic electrodeposition coating with low cured temperature are pointed out.
