  • Silane-containing high modulus urethane adhesives
    Patent number: 11732167
    Abstract: Moisture-curable, one component adhesives contain an isocyanate-terminated prepolymer, a low molecular weight polyisocyanate compound, a hydrolysable mercaptosilane, a urethane catalyst and a carbon black filler. The adhesives exhibit an excellent combination of high modulus, excellent hydrolytic and heat stability, and high sag resistance.
    Type: Grant
    Filed: November 9, 2021
    Date of Patent: August 22, 2023

  • Silyl terminated prepolymers, method for making them and adhesive compositions made therefrom
    Patent number: 9765247
    Abstract: The invention is an adhesive composition comprising a silyl terminated prepolymer having a number molecular weight average (Mn) of about 8,000 to about 80,000 g/mole, a filler, and a silanol condensation reaction catalyst. The silyl terminated prepolymer is comprised of a polymeric backbone of alkylene oxide and at least three urethane groups and at least two terminal groups comprised of a silicon atom having at least two alkoxy silane groups, wherein each silicon atom in the terminal groups is separated from the urethane groups in the polymeric backbone by an amount of alkylene oxide that has a molecular weight of 200 to 15,000 g/mole.
