Optimizing Premium Equipment to Complete the Powder Coating Process
At Primo Powder Coating & Sandblasting, we use a special powder coating gun that works to deliver a superb thermal coating service. The products we use may either be thermoplastics or thermosets that are cured under heat until they form a protective layer over each metal surface.

What is Powder Coating?
This is a type of coating technique applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. This method is preferred for creating a finish that is tougher than the results achieved from a conventional paint.

Usage and Applications
Powder coating is mainly used for metals such as “white goods,” aluminum extrusions, as well as automobile and motorcycle parts. Modern technologies now also allow various other materials including MDF (medium-density fiberboard) to be powder coated using different procedures.

Versatile and Cost-Effective Metalizing
Steel materials of various shapes and sizes may be metalized either on-site or in-shop before construction. This coating method is great for protecting steel structures, such as heavy-duty bridges. You can expect results to last for 10 years without any signs of rust or corrosion.

The Complete
Powder Coating Process -
-
Step 1: Preparation
The metal component will be chemically stripped or sandblasted of residual paints and solvents, with the goal of removing impurities and signs of corrosion. This step leaves the material’s surface clean and ideal for powder coating adhesion.
-
Step 2: Pre-Baking
We will pre-bake the component to remove impurities that can bubble up and result in an unappealing final result.
-
Step 3: Polishing
Our team will move forward with the polishing process within a solvent bath. We will also apply another pre-baked coat, which will be heated once more.
-
Step 4: Powder Coating Application
The part will now be brought to a spraying booth, where an electrical charge will be applied on its surface. This is also the step where the powder coating will be administered with a specialized spray gun.
-
Step 5: Oven Curing
We will then move the metal component to a special-purpose oven, where the powder coating is allowed to melt into the surface. This allows for the complete adhesion of the coating.
-
Step 6: Cooling Stage
Once we’re through, the parts will be removed from the oven and allowed to cool.
-
Step 7: Inspection
Finally, our specialists will complete thorough inspections of each part, making sure that the applied powder coating does not show any defects in color or other visual aspects.
