    摘要: 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.

    摘要: A reaction product of the co-dehydration of a sugar alcohol and a reactant polyol having a number average hydroxyl functionality less than 4.0 is disclosed. In some aspects the sugar alcohol comprises mannitol, sorbitol, xylitol, erythritol, or mixtures thereof. In some preferred aspects the sugar alcohol comprises sorbitol. In some aspects the reactant polyol has an average molecular weight of from 40 to 500 Daltons. In some aspects, the reaction product may be suitable for the manufacture of polyisocyanurate foam. In some aspects the reaction product may be mixed with diluent polyols, such as diols, glycols, ethylene glycol, diethylene glycol, dipropylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol and mixtures thereof.
