What is EDT Coating?
Electrocoating, which is also referred to as electro deposition, electrophoretic deposition, CED Coating, CED Painting or electropainting, is an organic finishing process that uniformly applies thin-film primers and one-coat finishes to metallic substrates. Electrocoating resembles electroplating in that it utilizes an electrical current to deposit a coating onto substrates. However, electrocoating deposits water born paint onto substrates rather than metal ions.
EDT Coating Process:
The electrocoat process can be divided into four distinct steps:
1. Pretreatment
2. CED/Electrocoat Bath
3. Post Rinses
4. Baking
