Abstract: A nozzle assembly includes a mixing channel and an aerator. The mixing channel has upstream and downstream ends defining a flow direction through the mixing channel and includes a housing wall and a mixer. The housing wall defines a flow passage and includes an inlet portion and a tip orifice. The inlet portion disposed at the upstream end and configured to receive a first material and a second material. The tip orifice is disposed at the downstream end and is configured to emit a plural component material from the mixing channel. The mixer is disposed within the mixing channel and is configured to mix the first material and the second material into the plural component material. The aerator is configured to flow nucleation air to a location downstream of an upstream end of the mixer and into a flow of the plural component material.

Abstract: An apparatus for preparing a liquid material containing microbubbles includes a dispensing nozzle and a first positive displacement gas pump. The dispensing nozzles includes a material mixing channel, a rotary gas diffuser positioned in the material mixing channel, and a rotary mixer positioned in the material mixing channel downstream of the rotary gas diffuser. The rotary gas diffuser and the rotary mixer rotate about a common axis of rotation. The first positive displacement pump has a first gas outlet opening to the material mixing channel, which is directed at an outer circumference of the rotary gas diffuser.
