Electrophoresis coating – What is it?

What is Electrophoresis?

Electrophoretic coating, commonly referred to as EP-coating, e-coating, or e-painting, is a process that uses electrical current to apply a paint layer onto a metal surface. This technique is popular for its efficiency, consistency, and excellent corrosion resistance. During the process, the metal part is immersed in a water-based solution containing paint particles. When an electrical current is applied, the paint particles move toward and bond to the metal surface through electrophoresis. This method ensures that the entire object, including intricate shapes and hard-to-reach areas, is evenly coated. The coating thickness can be precisely controlled by adjusting the voltage, ensuring uniformity and accuracy across production batches.

Why are we talking about Electrophoresis?

In the coming months, we will be introducing more and more of our professional solar bollards with an additional electrophoretic coating. Following electrophoresis, the bollards are then powder coated to the relevant RAL. Often used on alloy wheels, this will further protect the aluminium from the elements, resulting in a fully corrosive-resistant solar bollard ideal for coastal locations. More information coming soon.
