International Classification:

C08G077/22

US Classification:

528/030000, 528/044000

Abstract:

This invention relates to chemical compositions comprising one or more urethane oligomers 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.

Inventors:

Linda Cote - Tucson AZ, US
E. McAlister - Woodbury MN, US

International Classification:

C08L075/00

US Classification:

524871000

Abstract:

The present invention relates to a fluorochemical composition for rendering fibrous substrates oil repellent, water repellent and/or stain or soil repellent. Additionally, the invention also relates to fluorochemical compositions for providing stain release or soil release properties to fibrous substrates. In particular, the present invention relates to fluorochemical compositions that contain a fluorinated polyether compound that can be obtained by reacting an isocyanate component with a particular isocyanate reactive fluorinated polyether compound and a stain release compound. The invention further relates to a method of treating the fibrous substrate with the fluorochemical composition.
