Cationic and anionic technologies continue to grow in both the automotive and general industrial markets. Auto frames, engine cradles, radiators, fasteners, HVAC, agriculture, and lawn and garden are some of the growth areas.
The Ford Motor Co. first used anionic E-coat to paint steel wheels and automotive bodies. Ford wanted a primer that could be applied uniformly over the entire surface and provide improved performance. At the time, most primers were applied by spray application, which was not able to apply a coating into the recessed areas of the car body with consistent coverage. The E-coat process allowed the entire body to be uniformly coated in about two minutes.
