Abstract:
Substantially solvent-free aqueous polyurethane dispersions and methods of making and using the same are provided. The substantially solvent-free aqueous polyurethane dispersions are provided in a substantially solvent-free system of a prepolymer made by reacting at least one polyol, at least one polyisocyanate, at least one isocyanate-reactive compound comprising one or more ionic or potential ionic groups, and at least one isocyanate chain terminating agent.
