Abstract

A convergent spray gun which combines a liquid resin and dry metallic powder externally of the nozzle of the spray gun that utilizes a pair of diametrically opposing passages disposed at 0.degree. and 90.degree. relative to the central resin discharging orifice where the central orifice is approximately 0.015 inch and the air for atomizing the fluids is approximately 0.187 inch and the atomizing angle is approximately 180.degree.. The metallic filler is added to the plume of the convergent spray at the low pressure section and the ratio of the fluids are controlled by a computerized system. The spray gun, controls and mixing chambers of the resin (two part) and powder fillers are housed in separate rooms and the dust where the powder fillers are metered is controlled.
