Abstract
An apparatus and method for powder coating the surfaces of objects provides a spray source of charged powder coat particles that engage the surface of the object. The thickness of the layer of particles can be regulated by measuring the resulting electrostatic surface potential generated by the particles. The layer of particles is treated by applying a balanced air flow positively and negatively-charged air ions that neutralize and transport surface particles from the object. The resulting surface has an electrostatic surface potential that is substantially equal thereon. This equal electrostatic surface potential translates into an even thickness coating along the object's surface. The treated surface is then cured by conventional heating and cooling processes to form a finished powder coat finish.
