Abstract
A disposable synthetic resin spray nozzle assembly for spraying reactive multi-component liquid mixtures includes a static mixer and an air or gas manifold. The static mixer has an elongated mixing tube containing a mixing element, and a liquid dispensing nozzle is formed at the downstream end of the mixing tube. A one-piece manifold has an inner wall which includes a mixer support section sealingly mounted around the static mixer, an air inlet section for receiving an air supply through a conduit, and an air dispensing section which, together with the outer wall of the liquid dispensing nozzle, forms an air dispensing nozzle. The reactive liquid mixture is atomized by air that supplied through the air dispensing nozzle.
