Beginning in the late 1950’s, electrodeposition methods were developed to improve the corrosion resistance in automotive parts. Today, nearly all automotive manufacturers use this process to coat automotive components worldwide.

In cathodic paint applications, anode cells are used to apply a direct current to the paint bath, allowing the positively charged paint particles to become attracted to the cathode, also known as the item that is being painted.  The anode cells also remove excess acid within the paint bath, in order to maintain the paint chemistry and pH, and the Ultrafiltration elements are able to recover paint solids and provide a clean rinse solution for closed loop systems.
