FAQ's
In essence, these terms are often used interchangeably to describe the same process. The differences are mainly in terminology rather than the actual coating process itself.
- CED Coating (Cathodic Electrodeposition):
- Also known as electrophoretic coating or e-coating.
- Uses an electrical current to deposit a coating onto a conductive surface.
- Commonly used in the automotive industry for its uniform and durable finish.
- ED Coating (Electrophoretic Deposition):
- Another term for CED coating.
- Refers to the same process of using electrical current to apply a coating.
- Ecoat (Electro Coating):
- Yet another name for CED coating or ED coating.
- Emphasizes the electrochemical process used to apply the coating.
- Electrophoretic Coating:
- A general term that encompasses CED coating, ED coating, and Ecoat.
- Refers to the overall process of using electrical current to deposit a coating.
CED stands for Cathodic Electrodeposition, which is a type of electrophoretic deposition where the coating is applied to the surface when it is negatively charged and immersed in a paint bath.
ED/ CED coating involves immersing the conductive object in a bath of paint or coating material. When an electrical charge is applied, the paint particles migrate and adhere to the surface of the object due to the opposite electrical charge between the object and the paint.
ED/ CED coatings offer excellent corrosion resistance, uniform film thickness distribution, and high-quality coverage even on complex shapes. They also provide a more environmentally friendly coating option compared to some traditional methods.
ED/ CED coatings are commonly used in industries like automotive, appliances, electronics, and various metal finishing applications where corrosion protection and consistent coating thickness are essential.
The Salt Spray Test (SST) life of CED (Cathodic Electrodeposition) or ED (Electrophoretic Deposition) coating typically ranges from 720 to 1200 hours according to ASTM B:117 standards. This means the coating can withstand exposure to a salt spray environment for this duration without significant corrosion, making it highly desirable for industries requiring durable and corrosion-resistant finishes.
The full form of CED Coating is Cathodic Electrodeposition Coating. It is sometimes also referred to as KTL coating (German: Kathodische Tauchlackierung).
Powder coating is a dry finishing process in which powdered paint is electrostatically applied and then cured with heat. CED coating (Cathodic Electrodeposition) is a wet coating process in which a part is dipped into a paint bath and coated using electrical current. Powder coating forms a thick, decorative outer layer, while CED coating offers superior corrosion resistance and is often used as a primer layer in the automotive and industrial sectors.
CED coating formulations typically consist of water-based epoxy or acrylic resins, pigments, corrosion inhibitors, surfactants, and additives. These components are dispersed in deionized water and applied through an electrochemical process. The exact formulation can vary depending on the desired properties, like corrosion resistance, thickness, and conductivity.
“CED material” usually refers to the special type of electrically conductive paint or emulsion used in the CED process. It contains resins, pigments, corrosion-resistant agents, and other chemicals that help in creating a uniform, durable, and anti-corrosive film on the metal surface when applied with electric current.
