Abstract

A spray head for use with conventional air-atomizing spray equipment is disclosed which has spray-forming means that includes a secondary atomization annulus which provides improved atomization of liquid materials and which is especially suitable for spray devices having electrostatic induction charging means. The secondry annulus minimizes deposition on the spray head of particles electrically charged with a polarity opposite that of components of the spray head and provides re-atomization of sprayable material which collects on the walls of the nozzle.
