Apparatus for coating substances with inductively charged resinous powder particles
Apparatus for coating substances with inductively charged resinous powder particles
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 109 to about 1013 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.
