Abstract
The present disclosure relates to an alkoxysilane functional polyurethane-urea that can be used to prepare an adhesive or coating composition. The polyurethane-urea is obtainable by polymerization of reaction components comprising (a) an alkoxysilane functional thioether diol; (b) a polyisocyanate; and (c) an alkoxysilane functional aspartate ester, wherein the alkoxysilane functional aspartate ester is a Michael addition product of an amino-functional silane and an unsaturated diester. The polyurethane-urea has a low viscosity and can be used in solvent- and water-free adhesives or coatings. The adhesive or coating can be applied to various substrates such as wood, wood-containing composite, metal, plastics, paper, stone, glass or concrete.
