Electrophoretic Coating

Electrophoretic Coating


Material Data

The principal purpose of this coating is anti-corrosion protection and an excellent surface preparation for the subsequent elements of the paint system


  • Handling – After any accompanying orders have been processed the “parts” will be transported from the receiving Bay to the Coating Line. The “parts” are then individually hung onto specially designed “jigs” and are carried by the transporter system throughout the entire process.


  • Pre-Treatment – The “parts” proceed along a transporter-based dip line into each of the treatment processes, the parts are cleaned and acid pickled. For the pre-treatment of metal surfaces, we use the Henkel “Tec-Talis” pre-treatment coating. This novel Zirconium based chemistry provides enhanced protection on e-coated material. When sealed with epoxy resin cathodic electro-paint it will meet and exceed all current automotive paint work test criteria. The pre-treatment chemistry is monitored and analysed daily by our on-site chemist, to ensure a high quality finish.


  • ED Painting – Immediately after leaving the final stage of the pre-treatment the “parts” are dipped into a large bath of cathodic electro paint. The electro-paint used is supplied by PPG, and cathodically deposited onto the “parts” to a thickness of 15 – 20 μ or higher if specified. The paint is analysed daily to ensure the integrity of the finish and to optimise efficiency.


  • Post Treatment – To seal the cathodic electro-paint the “parts” must be baked. The same transporter system carries the dipped “parts” into the oven, which is heated to 200OC.


  • Handling & Packaging – Upon exiting the oven the “parts” are allowed to cool before being removed and packaged according to stipulated requirements. Only when the process is fully complete, are the “parts” handled. Loading and unloading are the only operations which involve manual handling.


  • Colour Black RAL 9005
