Q.

What is E-Coat?

A.

The Electrophoretic Deposition process (aka "Electrocoating", or "E-Coat" for short) is one of the coating methods in the field of surface finishing. It uses a tank/bath filled with a special E-Coat paint, and the coating target and an electrode are placed in the tank. Electricity is applied between the target and the electrode in order to create a voltage potential difference, resulting in electrophoresis to deposit paint film on the target.
E-Coat is limited to processing targets with conducting properties. However, it is economical when processing in a mass scale production line setting, and extremely effective, especially when coating areas that are difficult for other methods to paint. The coated film has excellent adhesion, making this an ideal method for products requiring anticorrosive properties.



Q.

What is the difference between Cationic and Anionic E-Coat?

A.

E-Coat is either Cathodic or Anodic process. In Cathodic E-Coat the coating target is the cathode (-), and the electrode is the anode (+). Anodic E-Coat is the opposite, making the coating target the anode (+), and the electrode as the cathode (-). As a result of this difference, the E-Coat paint is also different, as well as the E-Coat Systems. 



Q.

How Long does Membrane Electrode Last?

A.

It heavily varies based on the usage. In general it is understood that it corresponds to the lifetime sum of electrical current passage. With our Tectron®, on average our customers replace them every 7~10 years.
