STAIN RESISTANT POLYURETHANE COATINGS

摘要

A chemical composition comprises one or more urethane oligomers of at least two polymerized units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon-containing urethane oligomers, wherein said 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 fluorocarbon monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof, (d) one or more silanes, and (e) one or more stabilizers comprising one or more reactive groups.
