ABSTRACT:
The disclosed one-part curable polyurethane prepolymer compositions comprise a continuous phase and, distributed uniformly through this phase, a discontinuous phase containing a polyol curing agent of the pentaerythritol type. At moderately elevated temperatures, the polyol phase begins to enter into a curing reaction which has a single exotherm peak. The prepolymers are made from aliphatic or cycloaliphatic polyisocyanates and polymeric polyols. The one-part curable system is stable for long periods at room temperature. The curable polyurethane systems can be used in adhesives, coatings, sealants, and similar applications.
