Surface Finish(E-Coating):

Technology Introduction:
Electrophoretic coating (E-coating) is the coating at the Yin and Yang poles, under the action of voltage, the charged coating ions move to the cathode, and interact with the alkaline substance produced on the cathode surface to form insoluble substance, deposited on the surface of the product.
Advantage:
E-coating paint film has the advantages of full, even, flat and smooth coating.
Its hardness, adhesion,Corrosion resistance, impact performance, permeability performance is obviously better than other coating process.
