The degree of compression of powder coatings is a value calculated from the packing density and loose density. It is one of the important parameters to evaluate the fluidity of powder coating dry powder. Generally, it is inconvenient to use when the degree of compression of powder coatings is greater than 25%, and if it exceeds 30%. , the effect of electrostatic spraying is not good.
The results of the degree of compression are expressed as follows:
