The Importance of Being Earnest.. About Particle Size Distribution

Although most powder coating will have a particle range size of 20 - 100µ (Microns), the Median is what you want to concentrate on. Typically, most of PTI’s powder coatings have a Median size of 40µ, +/- 3µ. As a powder coating professional, it is important understand the particle size distribution of your coating because that will help you better ascertain the true value of what you are buying.

Cheaper powders will often time contain higher percentages of small and large particles that won’t take a charge. This means that all of your powder that is too fine or too large will simply end up as waste and never make it to the part.
