Powder coating density

The density of powder coating depends on its composition and formulation. Generally speaking, the density of powder coating ranges from 1.2 to 1.8 g/cm3. The specific density may also be affected by factors such as particle size, shape and porosity.

Further subdivided, the following are the density ranges of several common powder coatings:


  1. Pure polymer powder coating: Its density is usually between 1.2 and 1.5 g/cm3. This type of powder coating is mainly composed of pure polymers, such as polyester, polyurethane, etc.


  1. Metal powder coating: Due to the addition of metal particles, the density of metal powder coating is relatively high, usually between 2.0 and 5.0 g/cm3. Metal powder coating can include aluminum powder, copper powder, iron powder, etc.


  1. Hybrid powder coating: This type of powder coating generally contains polymer and metal powder, so its density is usually between pure polymer and metal powder coating. The specific range will be affected by different formulations.


It should be noted that density is only one of the physical properties of powder coatings, and other factors such as fluidity and coating effect need to be considered in actual applications. Therefore, when selecting and using powder coatings, it is necessary to consider the specific process requirements comprehensively.
