We are founding members of The Electrocoat Association and proud to have employed three recipients of the prestigious Brewer Award for excellence and innovation in electrocoating technology.
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.
The parts pass through a pretreatment process, then the cleaned parts enter a temperature-controlled grounded steel tank, which is lined with chemically-resistant dielectric material. After a 90 to 120 second dwell in the water based electrocoat paint solution with a DC electrical charge applied, parts are conveyed through a series of counterflowing permeate rinse stages to remove undeposited paint. The parts are then conveyed to an oven to cure the electrocoat paint coating prior to unload.
