What is electrodeposition coating?


Electrodeposition coating is a coating method that forms a coating film by passing electricity between the product and electrodes in the electrodeposition paint. Depending on whether the object to be coated is an anode or a cathode, it is divided into anionic electrodeposition coating and cationic electrodeposition coating. The film thickness is easy to control, and a uniform coating film can be formed even on products with complex shapes. In addition, since it is a water-based paint, the amount of organic solvent used is small, and it is effective in reducing VOCs (Volatile Organic Compounds).
