Title: Silante terminated polyurethane

Abstract: A curable, alkoxysilane-functional polyether urethane composition formed by combining a) a first silane terminated polyurethane prepared by reacting i) a mono-functional compounds with ii) an isocyanate component containing two isocyanate groups, the reaction product reacted with iii) a compound containing an isocyanate-reactive group and one or more reactive silane groups to form a moisture-curable, alkoxysilane-functional polyether urethane; and b) a second silane terminated polyurethane prepared by reacting i) an alkyl monofunctional alcohol, amine, and/or thiol, with ii) an isocyanate component containing two isocyanate groups, the reaction product reacted with iii) a compound containing an isocyanate-reactive group and one more reactive silane groups. The urethane composition can be used in coating, sealant and/or adhesive compositions. The coating compositions are used to form a coated substrate. The sealant and/or adhesive compositions are used in a method of joining a first adherend and a second adherend to form a bonded assembly.
