E-coating is an electrochemical finishing process used to apply a uniform, protective coating to metal parts. Also known as electrophoretic coating or electrocoating, the process involves immersing the metal component in a water-based paint solution and applying a direct electrical current. This causes the paint particles to migrate and bond to the surface, forming a smooth, consistent film that adheres even to hard-to-reach areas.

E-coating delivers excellent corrosion resistance, durability, and coverage, making it ideal for complex metal parts in demanding environments. It is commonly used in the automotive, appliance, and industrial equipment industries. The process is environmentally friendly, with low VOC emissions, and can serve as a standalone finish or a base layer for powder coating or topcoats.
