• Precipitation of paint particles
onto a substrate
• Highly efficient and automated
process
• Paint deposition is regulated by
voltage
• Coating can be either anodic or
cathodic
Depending upon the polarity of charge, electrocoating is classified into
Anodic :- In Anode Electocoating, the part to be coated is the anode with a positive electrical charge which attracts negatively charged 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 system. Anodic coatings are economical and offers excellent colour and gloss control.
--------------------------
Cathodic :-
This the type of electrocoating is used in JJ coating. The Cathodic Electrocoating is just the opposite of anodic process. In cathodic electrocoating, the part to be coated is given a negative charge, attracting the positively charged paint particle. The reversing of anodic polarities greatly reducing the amount of ions entering the cured film and thus enhances the properties of cathodic electrocoated products.
