What is Electropainting ?
Electropainting is a painting method, which uses an electrical current to deposit paint on conductive materials.
The electrocoat system applies a DC charge to a metal part immersed in a bath of oppositely charged paint particles. The paint particles are attracted to the metal part and paint is deposited on the component, forming an even, continuous film over the entire surface, until the coating reaches the desired thickness. At that thickness, the film insulates the part, where attraction stops and the process is complete. Depending on the polarity of the charge, electrocoating is classified as either anodic or cathodic Electrocoat is an electrically applied paint coating. It is also known as E-Coat, electrocoat, electrocoating, and electrophoretic coating, also cathodic or cationic coating.
E-coating was developed originally for the automotive industry because it is economical and provides superior coverage, adhesion, and corrosion resistance. It coats aluminum, zinc, brass, steel, any material that conducts electricity. Usually applied on top of suitably pretreated surface prepared by aqueous degreasing to remove light oils, greases etc then a conversion coating of usually zinc phosphate to provide a suitable key for the electropaint to adhere to and provide corrosion protection.
Typical parts coated using this process are pressings, stampings, forgings, castings, spinnings provided for a wide range of applications including automotive, agricultural, industrial, household, electrical.
Electrocoat applied using the correct conditions, has excellent corrosion resistance qualities; typically 1000 salt spray (automotive) and is extremely durable. Subsequent coatings of powder coat or wet spray will enhance cosmetic, corrosion and Ultra – violet resistance.
