This is a method which reduces overspray employing an electrostatic field to direct and confine the spray deposition to the surface of the object being coated.

The spray gun is connected to a source of very high voltage and the article to be coated is earthed so that the spray emerging from the gun is immediately drawn to the object. ‘A further advantage is that parts that are not easily accessible, sharp edges, such as car door edges are more certain to receive a coating.

The process gives a 'wrap around' effective, the overspray that passes the object is drawn back to it from the other side. When used with metallic finishes, the electrostatic application gives a complete and uniform metallic laydown, making production line application more uniform. Electrostatic charges of 0.5 to 100 kilo-volt are often used and may be used in conjunction with

Convention and pressure feed spray, airless and air-assisted airless, powder coating and electrostatic bells.
