  • Urethane resins
    Patent number: 6878794
    Abstract: Amine-terminated urethane oligomer compositions are described that include very high oligomer concentrations. The compositions are melts of the amine-terminated oligomers. The compositions can include one or more property modifiers. The compositions are useful in the formation of crosslinked copolymers, especially with epoxy resins. The resulting copolymers are useful in the formation of coatings.
