Electrostatic painting is the application of electrostatically charged paint particles to an oppositely charged workpiece followed by thermal fusing of the paint particles to form a cohesive paint film. Both waterborne and solvent-borne coatings can be sprayed electrostatically.

Sometimes it is desired to have a large working area in a tank where, for example, a conveyor belt containing car bodies can be passed through for electrostatic painting. One way to accomplish this is to put a series of propeller mixers in a side arm of the long side of the tank, so that the flow is directed into the middle zone, but there are no mixer shafts or impellers in the center to impede the flow of the parts through the equipment.

Surface finish of parts is another important source of economic advantage. Surface roughness depends on the orientation of glass fiber. The process was optimized using data from surface smoothness measurements. A conductive RIM was developed to produce material ready for electrostatic painting without the need for further surface preparation. 

There has been a trend in recent years to move towards the electrostatic deposition of paints for exterior automotive applications. Reasons for this include improved paint transfer efficiency. Normally, plastic parts need to be painted with a conductive primer prior to the electrostatic painting of base and clear coats. One of the most recent developments in the area of external automotive applications is that of intrinsically conductive resins for electrostatic painting. Currently there are commercial applications for body panels that utilize PPE/PA that contains carbon black as the conductive component. In the USA, a mirror shell application uses PPE/PA where the conductivity is achieved through the incorporation of graphite nano-tubes.
