Electrophoretic coating is a commonly used surface coating process. By immersing aluminum profiles in electrophoretic paint, the electric field is used to evenly adhere the paint to the surface of the aluminum profiles to form a protective film, which improves the weather resistance and appearance quality of the aluminum profiles.
The process includes the following steps:
Prepare the paint: Select the appropriate e-coat, stir and mix.
Pre-treatment: Aluminum profiles are cleaned and surface treated to provide good adhesion.
Electrophoresis: The aluminum profile is suspended in an electrophoresis tank. The particles in the coating solution are charged and adhere to the aluminum surface through the electric field to form a uniform coating.
Curing: After electrophoresis, the paint applied on the aluminum profile is cured by baking or curing oven to ensure the hardness and durability of the coating.
