WATER-CURABLE POLYURETHANE RESIN USING GYPSUM AS A FIXING MATERIAL AND A WATER-CURABLE POLYURETHANE CASTING SHEET

摘要

PURPOSE: A water-curable polyurethane resin is provided to increase the strength of a water-curable polyurethane casting sheet and to prevent the leaning of the resin which can be generated in a long-term storage.;CONSTITUTION: A water-curable polyurethane resin comprises a polyurethane compound including a polyol component and aromatic diisocyanate; a catalyst used for the reaction of the polyol component and aromatic diisocyanate; an antifoaming agent for removing bubbles generated in the reaction of the polyol component and aromatic diisocyanate; a lubricant for imparting lubrication to the polyurethane compound; and gypsum cured by reacting with water.;COPYRIGHT KIPO 2010
