ABSTRACT:
An apparatus for improving the electrostatic charge developed on a resin powder composition for electrostatic coating of solid objects and the method of application thereof. The apparatus comprises a device for charging the powder by electrical induction/conduction such that the powder particles have a resistivity of from about 10.sup.9 to about 10.sup.13 ohm.meters at 20 percent relative humidity and spraying the charged powder onto an grounded solid object to which it adheres prior to the thermal fusing to produce a permanent finish.
