Abstract: A copolymer-filled crosslinkable silane-terminated polymer having at least one crosslinkable silyl group in each molecule is provided. The copolymer-filled crosslinkable silane-terminated polymer is the reaction product of a copolymer-filled polyol and an isocyanate capped hydrosilylated polymer. The isocyanate capped hydrosilylated polymer is the reaction product of at least one isocyanate and a hydrosilylated polymer. The hydrosilylated polymer is the reaction product of a polymer having at least one unsaturated group and at least one alcoholic group in each molecule and a compound having a hydrogen-silicon bond and a crosslinkable silyl group in each molecule. The copolymer-filled crosslinkable silane-terminated polymers exhibit improved modulus and tensile strength properties while maintaining elongation properties.

Abstract: The present invention discloses polyurethane dispersions based on aliphatic isocyanates which form hard coatings wherein the coatings also have good solvent resistant properties. The enhanced properties of the coatings are achieved by including from 1 to 8 weight percent of a high functional polyol in the polyol formulation for producing the dispersions.
