The so-called electrophoretic coating line is a coating technology in which a coating material is immersed in a water-soluble coating as an anode (anodic electrophoresis) and a corresponding cathode is installed. A direct current is applied between the two electrodes, and the physical and chemical effects produced by the current are utilized to apply the coating uniformly on the coating material.
Electrophoresis is divided into anodic electrophoresis and cathodic electrophoresis. In cathodic electrophoresis, the coated material is the cathode, and the impregnation method and principle are the same. Both processes have their own advantages, and the appropriate process is generally selected according to the characteristics of the product.
