Abstract:
A polyurethane resin useful for the production of a heat-insulating sash with a coated aluminum frame in which displacement (void caused by peeling) caused by shrinkage and expansion due to hot-cold cycles does not occur so that rain water can not enter the heat-insulating sash. The linear expansion ratio of the polyurethane resin is decreased by including wollastonite in the polyurethane-forming resin.
