Abstract: A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated.
