E-COATING

The Specialist

Electro coating is a form of painting which gives a metal an organic finish by using electrical current to deposit the paint on the surface of the component to be painted. The process work on the simple principle of “OPPOSITE’S ATTRACT”. The Paint particles are drawn to the metal part and paint is made to deposit on the component, forming an even/continuous film over the surface, in every nook and corner, until the coating reaches the desired thickness. At the thickness the film insulates the component and the attraction of paint particle stops and electro coating is complete.

TYPES OF E-COATING
Anodic Coating

In Anodic Electro coating, the part to be coated is the anode with a positive electrical charge which attracts negatively charges paint particles in paint bath. In the anodic process, small amounts of metal ions migrate into the paint film, which limit the performance properties of these systems. Their main use is for products in interior or moderately aggressive exterior environments. Anodic coatings are economical and offers excellent color and gloss control.

Cathodic Coating

Cathodic Coating System in JJ Coatings – Colour Black Epoxy – Power Corn 6000 CX

In this system of Electro coating the part to be coated is given a negative charge, attracting the positively charges paint particle. The Reversing of anodic polarities greatly reduces the amount of ions entering the cured paint film and thus enhances the properties of Cathodic Electro coated products. Cathodic electro coating is high performance coatings with excellent corrosion resistance and can withstand the harshness of exterior environment.
