Abstract: A nozzle assembly includes a nozzle housing (86) defining an inner chamber (91) and a mixer (90) disposed within the inner chamber. The nozzle housing includes a nozzle housing and a nozzle orifice. The nozzle receive is configured to connect to a sprayer housing and to receive a first material, a second material, and air. The nozzle orifice is configured to spray a plural component material formed by a mixture of the first material and the second material. The mixer includes a shaft (92), an extension (94), an air channel, and inlet orifice formed in a first end of the shaft, and an outlet orifice formed between the air channel and a surface of the shaft. The extension defines a mixing channel extending between the shaft and the inner surface of the housing and the air channel is defined by an inner surface of the shaft and extends partially axially through the shaft.
