Product Overview
Anodic electrophoretic coating is a specialized coating applied to aluminum surfaces through an electrophoretic deposition process. In this process, the aluminum part is immersed in a bath of water-based paint, and an electric current is applied. This results in a uniform and durable coating that adheres well to the aluminum surface.
