<p>In an external mix, plural component application system, a first component is formed into a plurality of small, spaced streams arranged in an array (401) and projected at a substrate (14). A second component is formed into two air-entrained sprays and dispensed from nozzles (442a, 442b) and directed at the streams of the first component from adjacent the opposite sides of the array (401) to assist atomization of the streams into particles and to mix the components. A plurality of flows of compressed air are directed at the substrate (14) to from nozzles (441a, 441b) adjacent the opposite sides of the array (401) between the two sprays of second component to contain plural component emissions. A second plurality of flows of compressed air at lower flow rates is directed forwardly from apertures (450a, 450b, 450c, 450d) to inhibit an accumulation of the plural component material on the face of the nozzle assembly.</p> |
