Abstract: The disclosure provides methods for preparing a plural component material where part A and part B supplies are delivered from unpressurized storage containers. In use, a continuous stream of high velocity air moves through the static mixing nozzle, and the material streams may be intermittently moved into the nozzle and aerated with an air supply to cause the A and B materials to be mixed with each other and moved with the air to form the plural component materials. The plural component materials are delivered from a static mixing nozzle at pressures of less than 300 psi. Spray guns configured for preparing the plural component materials are also disclosed. Polyurethane foams, polyurethane adhesives, and polyurea coatings prepared by the methods are further provided.

Abstract: The present disclosure relates to a non-aerosol foam pump for use in association with an unpressurized liquid container and a foaming element comprising. The pump includes a liquid pump portion and an air pump portion. The liquid pump portion has a liquid chamber with a liquid internal volume and a shuttle liquid piston. The liquid chamber is in flow communication with the unpressurized liquid container and in flow communication with the foaming element. The air pump portion has an air chamber with an air internal volume. The air chamber is in flow communication with the foaming element. The liquid pump portion and the air pump portion have an activation stroke and a return stroke.

Abstract: A foam generator includes a container having a liquid. The container includes a container neck. A bubble generator is mounted to the container. The bubble generator has a liquid piston and an air piston that are mechanically connected together to simultaneously dispense the liquid and a flow of air. The liquid piston extends into the container as a bubble generator input stem. The liquid is received into the bubble generator input stem at a liquid piston intake of the bubble generator input stem. The air piston and the liquid piston feed both air and liquid to a mixing chamber that provides both air and liquid to a pair of mixing screens mounted on a bubble generator output stem. The bubble generator output stem is oriented below the bubble generator input stem. An inverted straw cover fits over the liquid piston intake of the input stem.
