E-coat – An Economical and Corrosion Resistant Finish

E Coat, EP Paint, Electropaint, Electrophoretic Paint - known by various names, has become established in recent years as an economical and corrosion resistant finish on its own or as a primer.

Predominantly used in the Automotive market for under bonnet and passenger compartment components it is a Black Paint finish with a uniform thickness ranging from 15 microns up to 30 microns. The coating systems economical benefits mean that it has in recent times been adopted by varying industries as an undercoat or finish of choice where cosmetics are less critical than performance.

The application process is a complete submersion coating process. The system is similar to a zinc plating application in that it starts with degreasing and rinsing, moves on to phosphate application to enhance corrosion resistance. The coating material is applied to the components using an electrical current (Cathodic Electro Deposition) in the bath of coating material.

The final coating is an organic coating that is around 20um thick on average. It has excellent corrosion resistance and good chemical resistance. Unlike many of the coatings that we offer at Plastic Coatings Ltd, this material is not UV balanced and therefore is best suited to applications such as engine compartment, under body, interior bracketry, braking components etc etc.
