Electro Coating Systems

Coatec India offers Electro Coating Systems. 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’. An electro coat 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 could be protective, decorative and may combine the properties of both depending upon the end use.

Depending upon the polarity of the charge, electro coating is classified as either: Anodic and Cathodic. Electro coat is utilised in a variety of industrial market segments. Each of these markets has specific performance requirements, leading to the development of a number of electro coat technologies to meet their needs. Electro coat has also become an accepted finishing method for new applications such as: specialty clear finishes over aluminium, 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.
