What is Powder Coating.
Powder coating is a tough paint like finish that is applied to metal surfaces and materials. The powder is a mixture of finely ground particles of pigments and resins
. Available in a vast array of colors from solid to metallics and candies. In addition to a wide array of colors is a selection of finishes
from low to high gloss, hammertones, wrinkles and rough textured surfaces. Different powders offer different protection characteristic such
as chemical resistance, weatherability and protection from uv light.
Applying the coating.
The coating is applied electrostatically by negatively grounding the part to be painted and spraying the powder through a gun which positively charges the powder particles.
The negatively charged part attracts the positively charged powder particles causing them to stick to the part.
Once the part is coated the part is placed in an oven and heated to 400 degrees F which causes the paint the melt and bond firmly to the
part. The result is and extremely hard permanent colored finish.
Items that can be powder coated.
As mentioned previously, powder coating relies on the process
of electrostatic attraction, therefore normally an item must have electrical conductivity to apply the powder coating. Generally metals lend themselves best
to the powder coating process. The second characteristic requirement is the ability to survive the beaking cycle once the powder has
been applied. The part must be able to withstand a temperature of 400 degrees F. (200 degrees C). Once again metals are ideally suited to this environment.
Preparing the surface.
As in any other type of painting surface preparation plays a key
role in the quality and adhesion of the finish. We provide in house sandblasting to remove old finishes, rust and prepare the surface for
a quality powder coat finish.
