Electrocoating
Parts Draining During E-coat
At the end of the process, when the body gets out of the E-coat bath, sometimes incomplete draining of the body can occur and this can produce problems during the baking phase. Could you tell me more about the nature of these problems? Do some special methods exist to avoid bad draining problems?

Anodic or Cathodic E-Coat?
I recently heard about a company using an anodic E-coat on castings, and that it cures at a much lower temp. If the anodic E-coat takes less energy to cure, why isn’t it more widely used?

The customer apparently feels that the zinc plating will provide an additional level of corrosion protection. However, we have sent requests for quote to three E-coaters and they have all elected to no-quote the project because of the zinc plating.

The spec called for electrocoat as a primer and a powder coating for the top coat. We have liquid and powder coating facilities in our plant, but we will have to send the parts to a contract coater for the E-coat process. Can you tell me why the E-coat process might be required instead of a liquid process?
