| Résumé : |
Cathodic electrodeposition (CED) coating was developed as a new type of industrial application for an anticorrosion coating since the mid 1970s. It has many merits, such as little environmental pollution, no fire hazard, excellent corrosion resistance, high throwing power and a degree of automation for coatings. Thus, it is widely used in automotives, light industry, agricultural machinery, household appliances, instruments, crafts, building materials and so on.
CED coating if often composed of water-soluble cationic resin, pigments and extenders, solvent and neutraliser, which is made by grinding. The cationic resin is the binder of the CED coating and is also the colour developing agent, which is vital to the properties of coating and its film. Thus, the cationic resin is one of the most important components for CED coating. Presently, the main research focuses on increasing kinds of cationic resin and improving the properties of cationic resin. In this paper, the advances of the cationic resin is reviewed. |
