Electrodeposition coating process

Electrodeposition coating is a coating method in which a product is immersed in a tank containing water-soluble or water-dispersible paint, and an anionic (+ pole) or cation (-pole) current is applied to the product.

Highly uniform coating is possible.

Excellent mass productivity because there is little color variation within the lot.
