All You Need To Know On E-Coat Paint

What is E-Coat Paint?

E-coating is a high-tech process mainly for applying a corrosion-resistant coating over goods. Other terms for e-coating are electrodeposition, electrocoating, and electrophoretic coating.

E-coating is an immersion wet paint finishing method to make goods durable and long-lasting. The substrate is soaked in a bath that often consists of any other water-based solution, paint, or epoxy.

After that, they pass an electric current to attract the particles suspended in the liquid solution. This helps the paint particles to deposit them onto the substrate surface. It creates an even and low-profile film over the entire metal surface.

This continues till you reach the desired film thickness. Varying the immersion time and current help control the thickness. Electrocoating is beneficial in working with complex shapes and high-quality parts.

Benefits of electrocoating include:

  • Superior corrosion resistance: Electrocoating ensures that the parts will get a protective and corrosion-resistant finish.
  • Uniform coating: E-coating offers highly precise coat and even film layers.
  • Good inter-coat adhesion with most topcoats: Good inter-coat adhesion with topcoats makes E-coating an excellent primer for almost all ferrous applications.
  • Durable and long-lasting finish: E-Coating can stand to the outdoor weathering and indoor environments.
  • Environmental friendly: Electrocoating is also eco-friendly. It produces no deadly air pollutants, heavy metals, or volatile organic Compounds. It is also EPA, RoHS, and OSHA compliant.
  • Cost-effective: Electrocoat is usually an affordable finishing application.
  • Versatile: Electrocoating is ideal for automotive or agriculture sectors as they provide superior salt spray, humidity, and better corrosion resistance.

Moreover, most e-coat systems are automatic. This means that it is possible to control the amount of paint for a product can be controlled well. It offers minimal waste, unlike a powder-based system.

What Is A Black E-Coating?

The black electrophoretic coating is electropainting in black.

In this process, metal components are submerged into the black electro paint bath and applying an electrical charge through it. Black e-coating is commonly used for cosmetic purposes in the automotive sector.

What Is Better E-Coating Or Powder Coating?

Powder Coating for Die Cating PartsE-coating and powder coating are ways of ‘finishing’ a product. Both involve applying a coating to a substrate to boost corrosion protection. This also promotes adhesion and increases wear resistance, etc.

  • Type of process: However, powder coating is a “dry” process, and e-coating is a “wet” process. You will see these processes in the automotive and heavy machinery sectors as a way of coating large-sized components. However, E-coating and powder coating can’t act as a substitute for the other.
  • Coverage: E-coating is usually the better option when coating parts that possess hard-to-reach areas. That’s because the object immersion offers a more even distribution of the coating.
  • Finish: E-coating offers a smooth surface finishing with almost zero waste and high levels of corrosion protection. It offers more control than powder coating. Furthermore, E-coating is great for higher volume production runs as it uses paint more efficiently than spray techniques.
  • Thickness: Although the powder coating offers no restriction on color, it produces a thick coating. With powder coating, the coated parts must be cured in an oven between 180 – 400 degrees Fah. It mainly depends on the temperature and coating of the part.

You can quickly get a thin coat with electrophoretic coating than with powder coating. This is especially important in the auto industry.

An e-coat can be used as a primer coat before painting to get better corrosion protection. This means e-coating is much better than powder coating. Get our superior quality e-coating services today.

Can You E-Coat Aluminum?

Yes. Aluminumconsists of an oxide film occurring naturally that shield it from corrosion. But additional protection helps in extreme environments.

E-coating works on different metals including aluminum, magnesium, brass, zinc, steel, gold, or any material that conducts electricity. E-coating aluminum is quite popular for industries. You can learn more details from this article about e-coating aluminum.

Can You Paint Over The E-Coat?

Yes, we can. Although electrocoating can work as a one coat final finish, most e-coats are generally epoxy-based and not UV resistant. Unless we fully guard it against UV rays, its surface can become unstable. Thus, to prevent paint layer separation and peeling, you need another layer of coating.

The top coating allows the electro coat to serve as an outstanding anti-corrosion primer to powder or liquid coats. It also offers color and gloss options that are not practically possible or can quickly change on an e-coat tank. The powder and e-coats have no problem combining as long as the e-coat is cured adequately for the correct time.

To provide resistance to ultraviolet rays, cathodic epoxy electrocoating is usually used. They are compatible with plenty of liquid and powder, and topcoats.
