Abstract

A silane-modified polyurethane prepolymer which is prepared by reacting an isocyanate-terminated polyurethane prepolymer with an end-capping agent comprising an substituted aminosilane having a hydroxy group or a mixture thereof with two or more hydroxyl substituted aminosilanes, has an improved viscosity, superior hardness, and enhanced durability. Accordingly the silane-modified polyurethane prepolymer is useful for preparing a polyurethane for sealing, coating, or bonding materials.
