Electrophoresis

Also called electro-deposition (ED). The working mechanism is similar to that of electro-galvanizing. What deposited to the substrate is no longer metal, but a kind of thermalsetting organic material. Then the wet film should be heated in oven to be cured.
Electrophoresis process has been applied in auto industry for more than 30 years. Today, it has become a standard method to treat the first layer of organic coating on body-in-white.
