What is electrophoresis surface treatment?

Electrophoresis coating can also be referred to e-coating, electrodeposited coating, electrocoating, electrophoretic coating and cataphoretic painting etc. In any case, the aluminum casting parts are immersed into solution in an electrified tank containing the required paint. The paint is drawn to the aluminum casting parts, where the addition or subtraction of electrons changes the paint from ions in solution to solid particles adhering to the aluminum casting parts.

Strengths:

Compared to powder coating, it is a high adhesive coating film  which is not easy to fall off and aging

Compared to anodizing, electrophoresis coating is a higher hardness coating film with great impact resistance

Colorful and metallic luster

Protective layer with higher corrosion resistance than anodizing and powder coating

Resistant to cement, mortar acid rain invasion

Better wear resistance, weather and chemical resistance than anodizing

Short processing time: as it works in water-based electrophoresis tank, it could finish the painting in several minutes which is easy to achieve the automated assembly line work.

High utilization of painting: Because the painting has low viscosity and the electrophoresis workpiece could be washed with water, the utilization of electrophoretic coating could be up to 95% or more by recovery equipment.

Electrophoresis finish is based on the anodizing finish, thus the quality would be better than anodizing finish. So the price of electrophoresis is also higher than that anodizing coating.
