WHAT IS ELECTROCOATING?
Electrocoating is an environmentally friendly coating process that uses electrical current to bond paint to metal products. Electrocoat finishing has very high transfer efficiency, uniform film build, and excellent corrosion resistance.
Cleaned, charged parts enter a temperature-controlled, grounded steel tank, which is lined with chemically-resistant, dielectric material. After a 90- to 120- second dwell, parts are conveyed through two or three counterflow rinses to remove undeposited paint. Excess paint is rinsed away with a solution of permeate (ultrafiltrate) and then cured.
