What is Electrocoat?



In short, electrocoating (also called e-coating or electrodeposition) is the process by which a metallic workpiece is submerged in a paint / water bath and electricity is used to deposit paint onto the workpiece. The electrodeposition process is the most automatic, controllable, and efficient method for applying a corrosion inhibiting primer to a metallic workpiece.

In a full system application, electrocoat is applied between the phosphate and primer layers.  The electrocoat layer is the primary corrosion protection layer.
