The Basics & Beginner’s Guide for Powder Coating

There is more to powder coating than meets the eye.  What is powder coating?  You coat a surface in a dry polymer based powder, curing it with heat, then letting it cool. The actual process is strait forward to learn, but knowing your equipment is always the first step to success. Let’s discuss how powder quality and the right tools can lead us to the perfect coat.

Quality Powders: Your Best Tool

Polyester powder coatings have some key characteristics that make them the preferred choice.  Producing a powder with consistent particle size is fundamental to transfer efficiency.  If the powder has particles that vary too much in size, they attach differently to the surface you are coating.  This also affects the edges, preventing them from holding an even coat.  The surface film will appear uneven as well.

How does that affect the durability of the powder coating?  An even coating enables high performance as the mechanical properties are consistent.  When baking the powder coating, an even smooth coat is key to avoiding “over baking.”  High quality powder coatings boast high rates of adhesion, gloss, impact hardness, and no fracture flexibility.

Powder Coating Guns

For small jobs these work well.  If the surfaces you need to coat are vast and there are many nooks and crannies, then consider purchasing a gun with wider customizability.  Custom coating equipment is also available.  We are happy to advise you.  Drop us a line.

Powder Coating Ovens and Infrared Lamps

Now that you’ve acquired the proper application gun and perfected your art of coating,  It’s time to turn up the heat. The goal is to heat your unit evenly.  This can be done in an oven or via infrared lamps.  There are even technologies in the works for utilizing LED lights to cure powder coatings.  Read the container that the polymer powder comes in for the correct curing temperatures.  The right sized oven and thermometers are key to getting professional results.

The Actual Process

  • Have a blast sandblasting. Oil and grease films must be removed.  Rust and oxidation needs to be blasted off.  Old paint or coatings should be thoroughly removed. Pure metal corrodes fast in moist environments.  Keep your prepared surfaces dry after sandblasting.
  • Now use the spray gun to apply the powder to your unit.
  • Move the powdered unit into the oven for an initial baking. This caused the coat to gel over.
  • After getting the initial coat to gel, the piece is brought back for a final powder coat. This additional dusting puts an elegant touch on the final product.
  • Last, back into the oven for another cooking and then leave the unit out to dry.
