Abstract
Method and apparatus provide effective application of plural component material from a plurality of air contained small streams, with stabilized stream formation, division and application and with a substantial reduction of VOC emissions in plural component applications, such as gel coat and wet-out applications in the manufacture of reinforced fiberglass articles. In the method, a flow of compressed air is delivered to an applicator and flows of the plural component materials are mixed and formed into a plurality of small, spaced streams extending from the applicator. The flow of compressed air is divided into a plurality of air flows that are directed about the plurality of small, spaced streams of plural component materials and generally adjacent and parallel to the streams. In apparatus for this method, a source of compressed air is provided and an applicator is adapted for connection to the source of compressed air and one or more sources of the plural component materials. The applicator includes a liquid nozzle for forming mixed plural component material into an array of small, spaced streams extending from the liquid nozzle and an air nozzle for directing a plurality of flow…
