Abstract: A method minimizes emissions while spraying a mixture of a resin composition and a polyisocyanate onto a surface. The resin composition has a hydroxyl content of at least 400 mg KOH/g and includes a blowing agent that is a liquid under pressure, a first polyol, at least one additional polyol other than the first polyol, and optionally a catalyst, surfactant, and water. The mixture is sprayed onto the surface to form a polyurethane foam having a closed cell content of at least 90 percent. The mixture is also sprayed through a spray nozzle at a spray angle corresponding to a control spray angle of from 15 to 125 degrees measured at a pressure of from 10 to 40 psi using water as a standard. The step of spraying produces less than 50 parts of the polyisocyanate per one billion parts of air according to OSHA Method 47.
