An Inside Look at Pneu-Mech E Coat Systems

As a leader in finishing systems, we have implemented our product’s superior coating technology to the automotive and other high-quality industrial markets. E-Coat (Electrophoretic Coating Painting) provides lower-cost surface protection and resistance to different elements than traditional painting methods. With our industry-leading european based E-Coat technology your product will maintain its high quality for extended periods.

Applications of E Coat Systems

E Coating is low-cost surface protection and resistant to different elements than traditional painting methods. The most significant advantage of E-coating is that it is an immersion process that provides thorough coverage of the product being coated. E-Coat systems provide your product with lower cost, high-quality surface protection, and resistance to different elements.

Industries & Products That Benefit from E Coat Systems

Many industries or products would benefit from e-coating systems. The automotive industry is one example because it would help them with corrosion protection and save on labor costs. The agriculture and construction industry is another example because it would help them with scratch and chemical resistance.

The automotive, appliance, and agriculture industries are the largest producers of products that could benefit from e coat systems. All three of these industries have extensive production facilities where corrosion protection is critical for their product lines. Corrosion protection is essential to ensure a product’s life expectancy and helps with warranty claims from clients. E-coating can also be used in the following industries:

Vehicles, E-coat technology offers corrosion resistance and requires less labor than traditional painting methods.

Industrial Machinery. The coatings can protect industrial machinery from environmental elements and corrosion.

Metal Decking. E-coating provides better protection against corrosion by using multiple layers on the metal panels.

How E Coating Works

Product is suspended from a conveyor system and is submerged during the E coating process. The coating material is electrically charged and the product is grounded through the conveyor system. Then, once reaching different voltage levels, the product accumulates layers of the coating until they are thick enough to prevent corrosion. Here are the basic steps of the process:



The pretreatment process is used to prepare the surface before being painted. The purpose is to remove any contaminants or other materials on top of the product, harming the coating. It also allows for a better bond between the coating and your product. Some examples of these materials are oils, waxes, mold release agents, and paint overspray. The surface should be free of any contaminants to ensure that your coating will provide the desired results and last for a long time without any degradation.

The next step is the application process. This is where the product is submerged in an electrically charged bath. The coating is applied as it proceeds through the e coat bath building coating thickness. This is important because it provides a more durable coating, enhancing its appearance and protecting it from rusting or corroding.

Post Application

Post Application

The post-application process is the final step in the e coat system. The product is rinsed with a special material to remove extra coating. Next we cure the product using a convection cure oven. The curing process helps the coating adhere better to your product and makes it more durable. This final step is essential because it helps to ensure that your product has a high-quality coating that will last for an extended period.

Benefits and Advantages of E Coating vs. Powder or Liquid Coating

Powder and liquid coatings have been the primary methods of coating metal substrates for many years. Powder coating is a good choice for applications where substrates are already in total production, as it can be applied quickly without interrupting the production line. However, powder coatings do not perform as well as e-coat or liquid paint under stress or high temperatures, and e-coating is popular in corrosion resistance environments.

Corrosion Resistance
E coat systems provide the best corrosion resistance compared to powder and liquid coatings, even when exposed to harsh environments like salt, high humidity, freeze/thaw cycles, etc. A powder or liquid paint will not provide the same corrosion resistance as e-coating because it deposits material on the surface of the metal that has roughness and porosity that provides crevice sites for corrosive elements to develop.

Level, Even Toned Coat
Because e-coating is an inorganic material that coats the surface of the metal, it provides a level and even tone that powder or liquid coatings do not. This allows for easy inspection and a much higher quality appearance when painting. Color variations will not be present in e-coat surfaces since they are applied uniformly to all surfaces.

Environmentally Friendly
One of the essential advantages of e-coating over other coating methods is that it is environmentally friendly. E-coat does not produce any harmful vapors or contain any volatile organic compounds (VOCs) that can harm the environment.

Efficient & Cost-Effective
E-coating is a very efficient and cost-effective way to coat metal substrates because it is a highly efficient application via a dip tank.

Density & Durability
E-coating delivers a superior coating performance than other coating methods because it has a denser and stricter structure. It is also durable, making e-coating a perfect solution for harsh environments.

E-coating is compatible with various substrates, including ferrous and non-ferrous metals, plastics, and composites. This allows multiple applications to be coated with e-coat.

E-coat is a durable coating that can last for many years if properly maintained. This makes e-coating a cost-effective solution in the long run.

Anodic E Coating

Anodic e-coating is a process that uses an electric current to apply a coating to metal parts. Anodic e-coating is often used on aluminum parts and can be cured at relatively low temperatures below 200F. Anodic e-coating can be either epoxy or acrylic. Epoxy coating is good as a primer for relatively heavy parts such as engine blocks. Acrylics are more commonly used for decorative applications where gloss, hardness, and corrosion protection are important.

Cathodic E Coating

Cathodic e-coating is a process that uses electric current to apply a primer coating to metal parts. This coating process is the performance benchmark in corrosion protection. The cathodic e-coating process begins by cleaning the metal parts in a multi-stage cleaning process that can consist of spray and dip tanks. Cathodic e-coat baths can apply either acrylic or epoxy coatings. Epoxy coatings have their benefit as a primer with generally strong salt spray, humidity and corrosion protection properties. Acrylic coatings also have good corrosion protection qualities but also have strong UV protection qualities.
