Electrostatic

Electrostatic

Material is atomized using conventional air (pneumatic), airless (fluid impingement), air-assisted airless, or rotary atomizer principles. Particles are electrically charged and attracted to the part substrate. Electricity may be turned off to permit normal spraying.

Advantages: “Wrap” around effect is able to coat the back of the part while spraying from the front. Material savings through minimized overspray. Can be used with or without electrical charge.
Limitations: Some conductive materials will require special equipment or paint reformulation. Parts must be conductive and able to be grounded. Difficult to penetrate cavities or recesses with power supply on.
