Central Wisconsin Finishing
Ensuring the best finish means a thorough surface preparation. At CWF*, the adhesion and durability of the finish is something we pay close attention to. Fabricated parts prepared in a variety of ways, including:
- 9-Stage wash system
- Shot blasting
When the components are ready, the seamless finish is the result of several, including:
E-coating is a liquid finish that's an electrically applied paint coating. E-coating is a process where a fabricated part bathes in a water-based solution containing paint emulsion. Adding voltage causes the emulsion to bond to the piece.
Powder coating involves spraying electrostatically charged particles to the surface of a component. Once applied, curing takes place in an oven causing the particles to melt and complete the chemical reaction producing the finish.
E-Coating vs Powder Coating
Comparing these two coating methods and saying one is better than the other isn’t fair. Each type of coating offers advantages over the other depending on the job.
E-coating does provide these benefits:
- At times, its less expensive over powder coating
- Greater control over coating thickness
- Even finish
- Protection from corrosion
- Strong adhesion
- Environmentally friendly
For protection against chemical and biological weapons, military vehicles commonly use a Chemical Agent Resistant Coating (CARC).
CARC paint is non-absorbent, providing resistance to chemical and biological exposure.
The three coating types of a CARC system include an aliphatic polyurethane, epoxy-polyamide enamel, and epoxy polyamide primer.
CARC advantages include:
- Metal strengthening
- Reducing IR signature
- Corrosion resistance
- Reduces friction
- Provides better paint adhesion leading to a better finish

Two-Coat Systems Using E-Coating
The two-coat process, including e-coating, provides greater protection from rust and corrosion over other metal finishing systems. Not having a basecoat shortens the lifespan of your component.
Is a Third Coat Necessary with a Two-Coat Topcoat?
As good as the idea of adding a third layer to a two-coat top coat sounds, there are actually several issues to consider.
How Do Companies Test the Strength of Their Topcoat?
Using a gravelometer test, under SAE J400 standards, creates a fair comparison between different topcoats supplied by different finishers.
