George Koch Sons designed and installed the first industrial electrocoat system in North America…

Since electrocoat’s earliest development, KOCH has worked with customers around the world to implement more than 300 high performance systems in a wide range of industries. Our highly experienced team of professionals provide full-service, turnkey system support with expertise in all process stages from pretreatment through final cure.

We have extensive experience in all major electrocoating techniques, such as continuous conveyorized systems, indexing systems, and bulk coating systems, where parts can be randomly packed. Our sales professionals will help you determine if your process is a good fit for e-coat, and, if so, the best application for you.

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.


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.
