What is Electrophoresis coating?

Electrophoresis coating (Also known as e-coating or electro-coating) is a painting process that parts are immersed in a paint solution contained in an electrified tank. The paint in the solution exists as ions with a positive or negative charge. When the parts are immersed in the tank, the paint migrates to the surface of the part. The paint ions gain or lose electrons at the surface of the part and are changed to solid paint that attaches to the surface. Normally the color is black or gray. It is generally used as a primer coating for metal products such as auto parts and hardware.


Benefits for Electrophoresis coating

Durable, lasting finishes. E-Coating is renowned for its ability to stand up to outdoor weathering and indoor environments where harsh chemicals may be present, as well as being chip resistant.

Complete coverage and consistent thickness. E-Coating works well with complex shapes, allowing for better coverage and thinner coats than other methods.

Efficient coating usage. E-Coating can be used for higher volume production runs and uses paint more efficiently than spray techniques, delivering a high-quality finish with almost zero waste.

Excellent primer. Good inter-coat adhesion with most topcoats makes E-Coating a great primer for almost all ferrous applications.

Environmentally friendly. A water-based, immersion technology, E-Coating produces no Hazardous Air Pollutants or Volatile Organic Compounds.
