What is ED Coating?
ED Coating is known by many names like Electrodeposition, Electropheretic, Electrophoresis Coating, Cationic E-Coat and Cathodic Electro Deposition just to name a few. It is an organic coating method that uses electrical current to deposit paint onto a part or assembled product. Because of its ability to coat even the most complex parts and assembled products with specific performance requirements, ED Coating is used throughout industry as a means to coat products in various categories such as: automobiles, automotive parts, transformers, metal office furniture, home appliances, fixtures and much more.
Why ED Coating?
Finishers choose ED Coating to provide their products with a durable, lasting coating and because ED Coating can be used as a primer, top coat or both, and also with other types of coatings, the versatility is endless.
ED Coating Process
This is a process where water based paint consisting of Pigment, Resin and Solvent is electroplated or coated on either ferrous or non-ferrous surface. This is usually found in automobile body parts as a prime coat before spray painting. With features like high throwing power; evenness in coating thickness and high corrosion resistant, it had already taken over many other processes such as epoxy powder painting, wet paint spraying and zinc electroplating.
