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.
