Not all powders are created equal

Custom powder coating formulas can be quite complex including multi-flake metallics, pigments, etc. Therefore, it's import to have a good understanding of not only spray gun settings, but also the characteristics of the various spray gun nozzles.

Considering Tips

To receive the best results there are several factors as an applicator you should consider in order to be assured your finished product will turn out successfully. One of these critical factors is the gun-tip or nozzle (if applicable). Selecting the wrong nozzle for the given job can mean the difference between having a happy customer or having one that brings you grief.

The image above shows how choosing the right gun-tip for your specific application is extremely important. This high-volume metallic flake wrinkle finish needs the right gun settings and gun tip to reach the desired result.

The image shows the difference in final outcome utilizing three common gun tips. The powder is from the same bag utilizing the same 55 KV setting and air pressures. Of course using our fluidized hopper also gives you the best chance for success, especially when applying metallic powders.

The image below is after applying Treasure Island PMB-10348. Same 55 KV setting and air pressures. The Cross tip versus Conical tip application thickness measures virtually the same at 2.3 mil and 2.1 mil respectively. As you can see, a much better flake application using the conical tip.

The below image illustrates the difference between 100KV charge potential compared to a 50KV charge potential. This affects non-bonded metallic powders alike, especially ones with a dense metallic flake.
