ABSTRACT:
We disclose a combination of three polyols. Polyurethane foams formed by reacting these polyols with an isocyanate exhibit good foam-substrate adhesion and good foam surface properties. This combination of polyols performs especially well in spray applications and is ideally suited for use in cold weather.
