A: Electrostatic spraying is an electrically charges spray that completely envelopes the object or surface being sprayed insuring complete coverage. In the fluorescent dye photo shown to the left, notice the even, complete coverage on the ball sprayed using electrostatics. The dyed spray was able to wrap around the ball on the left for even coating. However, the knob on the right was sprayed with the electrostatic system “off”. Without electrostatics the spray coverage is so uneven that the back side of the knob remains untouched and is able to reflect the evenly-coated electrostatic knob. The spray is condensed to 30-60 microns and the electrical charge gives it a much stronger than gravity pull, so the molecules find something to grab on to instead of just falling to the ground.
