This invention relates to chemical compositions comprising one or more urethaneoligomers of at least two repeating units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon-containing urethane oligomers. These urethane oligomers comprise the reaction product of (a) one or more polyfunctional isocyanate compounds; (b) one or more polyols; (c) one or more monoalcohols selected from the group consisting of fluorochemical monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof; (d) one or more silanes; and optionally (e) one or more water-solubilizing compounds comprising one or more water-solubilizing groups and at least one isocyanate-reactive hydrogen containing group. The chemical compositions of the present invention can be applied as coatings and these coatings can impart stain-release characteristics and resist being worn-off due to wear and abrasion.
