In this paper, a method to characterize the hiding power of powder coating by dispersing powder coatings in various dispersants and brushing obtained suspension coating was studied. When colorless, transparent and low-viscosity reagents reagent, containing epoxy functional group, is used as the dispersant of TGIC polyester thermosetting powder coating, the hiding power of this kind of powder coating can be accurately determined. When the dispersion concentration of powder coating is in an appropriate range (mass fraction 32%-45%), the hiding power has nothing to do with the concentration, and the test results reflect the properties of powder coating itself.
