The Benefits of E-Coating

The E-coating process offers many advantages. First, let’s explain what E-coating is and what it isn’t. E-coating is a process that deposits electro-deposition coating, electro-painting, or electrophoretic lacquering on the surface of a metal. Often associated with Electro-plating, E-coating is inherently different. The process of Electro-plating applies a metal to a metal, while E-coating is applying paint or lacquer. Powder Coating is another process that is sometimes confused with E-coating. E-coating is a “wet” process, while the Powder Coating process applies a dry powder of a combination of epoxy resins and curing agents. A spray gun is used to electrostatically apply the particles onto the surface of the substrate. In E-coating, the substrate is immersed in a bath of paint, epoxy or other water-based solution and cured in an oven to promote cross-linking. The following are the top three benefits of e-coating.


E-coating is an environment-friendly option. The process produces little to no hazardous substances, air pollutants, and volatile organic compounds.

Maximum Efficiency

Almost all the unused paint is recovered after the process to ensure maximum efficiency. While most lines have two, some have three post rinses to make sure there’s no buildup of residual paint. After the filtration of these post rinses, the paint collected during the rinse phase is added back into the application bath. Thanks to modern technology, most e-coating systems are now automated, meaning that you can fully control the amount of paint to be applied to increase efficiency and reduces waste.

Compatibility and Extended Lifespan

E-coating allows products to have a coating that’s not only high-quality but also durable. It’s strong enough to withstand extreme environmental conditions, such as water, and indoor conditions, such as chemical exposure.

Cost Effective

The best thing is that e-coating gives quality finish at low costs. The level of efficiency and environmental compliance of the process is second to none.
