VMT 2026 08 03 Electrophoretic coating (commonly known as E-coating or electrocoating) is a high-performance surface treatment for custom machined aluminum parts. It is a method of applying a protective or decorative coating to a metal object (which must be electrically conductive) through an electrochemical process. The important thing is that the E-coating is used to provide corrosion resistance, enhance aesthetics, and improve the durability of metal parts.
