Electrocoating
is an immersion painting process in which
charged paint particles are attracted to
an oppositely charged metallic surface. As the paint is deposited,
it forms a finish which begins to insulate the metal from the surrounding
charged solution. Deposition continues until the coating thickness
becomes sufficient to form a barrier against further paint attraction.
Electrocoating is an economical way to paint high volume parts
The E-Coat
Advantage
Electrocoating
offers several advantages in the finishing of metal products.
Corrosion resistance is superior to other
paint application methods because immersion E-Coat
provides a complete, uniform coating - even in corners, on edges,
and in hard to reach, partially enclosed spaces. Because the applied
coating contains very little water, there are no runs or sags, and
parts can be handled almost immediately. Consistent, controlled
application without spray gun error nearly eliminates the need for
manual touch ups.
E-Coating
dramatically cuts material costs because paint waste is minimal.
Virtually all of the coating put in the tank goes on the product
and stays on the product. In addition, low solvent, waterborne formulations
make electrocoating the perfect environment
- A friendly finish.
Drawbacks: Difficult color changes, not economical for low volume
operations.
