USE OF NON-FLUORINATED OR PARTIALLY FLUORINATED URETHANES IN COATINGS

摘要

The present invention is a method for imparting surface effects to a substrate using at least one hydrophobic compound with at least one linkage of Formula I: - NHC(O)-X- (I) wherein X is the residue of a cyclic or acyclic sugar alcohol which is substituted with at least one -R1; -C(O)R1; -(CH2CH2O)n(CH(CH3)CH2O)mR2; -(CH2CH2O)n(CH(CH3)CH2O)mC(O)R1; or mixtures thereof; where the cyclic or acyclic sugar alcohol is selected from a saccharide, reduced sugar, aminosaccharide, aldonic acid, or aldonic acid lactone; wherein each n is independently 0 to 20; each m is independently 0 to 20; m+n is greater than 0; each R1 is independently a linear or branched alkyl group having 5 to 29 carbons optionally comprising at least 1 unsaturated bond; and each R2 is independently -H, a linear or branched alkyl group having 6 to 30 carbons optionally comprising at least 1 unsaturated bond, or mixtures thereof.
