An electrostatic spray coating apparatus having a spray nozzle which has a spray orifice for atomizing coating material. The nozzle orifice may be roun d or, preferably, is in the form of a slot to impart a flat shape to the atomized material. The spray nozzle is mounted to be rotated on a body of the spray gun so that theatomized material particles are driven radially outw ards in addition to the forward direction and are thereby distributed uniformly in the cloud of sprayed mate rial. A brake may be provided to slow down the rotation when greater penetration int o cavities in the article being painted is desired. In invention may be used i n either power spray coating apparatus or liquid spray coating apparatus.
