ABSTRACT:
An external mix, air-assisted, airless atomization, plural component spraying system and method includes a first source of a first component, e.g., a resin; a second source of a second component, e.g., catalyst for the resin; spraying means to mix the resin and catalyst and direct the mixture to a substrate; a source of compressed air; and means for injecting the catalyst into the compressed air. The spraying means includes a nozzle assembly which comprises a liquid nozzle for forming the resin into a fan-like film with expanding edges extending from a liquid orifice, and a nozzle assembly for directing a flow of compressed air and catalyst at the fan-like film colsely adjacent the liquid orifice. In a preferred embodiment, compressed air is directed to impinge upon the expanding edges of the fan-like resin stream downstream of the impingement of the flow of compressed air and catalyst particles to capture from catalyst particles in small, uniform spray pattern. The flow of compressed air and catalyst can be juxtaposed to and interact with the fan-like resin film to assist in atomization of the resin and to mix the catalyst and resin particles in a more uniform spray pattern.
