The Electrophoretic Coating (e-coat) process is widely used in the automotive and other industries for corrosion protection as it offers the ability to deposit a uniform coating over an entire component including those with bends, cavities or areas which would be hard to coat with a conventional powder coat or liquid spray painting process.
The Euro Quality Coatings e-coating plant is an automatic finishing facility with zinc phosphate pretreatment and using cathodic epoxy black paint. This process is also known as Electrocoating, Electropainting, E Coating, Electrophoretic Deposition (EPD), KTL, E coat, EP coating, Cathodic Dip Painting (CDP) and Electrodeposition.
The e-coat process can be used to produce a basic coating in its own right by giving excellent corrosion protection to components not requiring a more decorative finish. It can also be used in conjunction with a powder coated finish on components that need a higher degree of protection and a more robust and aesthetic finish.

Euro Quality Coatings uses PPG Powercron 6200HE electrocoat but other trade names for electrocoating material includes KTL and cathoguard.
In line with the upcoming change in legislation, and the removal of Hexavalent Chromium from the supply chain in mid 2017 (all as per EU Regulation (EC) No. 1907/2006.), EQC continue to investigate the best manner in which to maintain their supply of a robust and quality driven pre-treatment process. At present our potential change could be to a German product “Oxsilan” as supplied by Chemetall.
However, with numerous Chrome Free alternatives available, EQC believe it to be a crucial part of their responsibility to their loyal customer base, to fully trial all variants thus ensuring the integrity of the products we apply is secure. We will aim to keep our customers fully informed of developments and will aim to make this change during early 2017.
11/04/17 – The date for the removal of Chromate Pre-treatments has now been pushed back, and EQC will provide further updates in due course. In the meantime, we will seek to continually improve our coatings adhesion quality, and environmental impact by investigating and trialing all pre-treatment options available to us.
