Electro Coating System

Coatec India offers an electro coating system. Finding application in the coating of automotive components to protect them from exposure to various elements, the electro coating system applies a DC charge to a metal part immersed in a bath of oppositely charged paint particles. The paint particles are drawn to the metal part and paint is deposited on the part, forming an even, continuous film over every surface, in every crevice and corner, until the coating reaches the desired thickness. At that thickness, the film insulates the part and the attraction of paint particle stops and electro coating is complete. Electro coating is a method of giving a metal an organic finish by using electrical current to deposit the paint. The process works on the simple principle of opposites attract. Also serving decorative purposes, depending upon the polarity of the charge, electro coating is classified as anodic or cathodic. Electro coat has become an accepted finishing method for new applications such as specialty clear finishes over aluminum, brass and zinc plate; extremely low gloss coating for military and photographic applications; chemical resistant coating, and transparent metallic-type finishes over nickel or zinc plating.
