Hydrophilic stain release agents

摘要: A composition comprising a self-emulsifiable or self-dispersible aqueous solution dispersion of at least one urea linkage-containing alkoxypolyoxyalkylene fluorocarbamate prepared by contacting (a) polyisocyanate which contains three isocyanate groups per molecule, (b) fluorochemical reagent the formula F(CF2)aCH2CH2OH, wherein is 4, 6, 8, mixtures thereof, provided that maximum 50% and (c) hydrophilic, water-solvatable molecule single functional group has reactive Zerewitinoff hydrogen atom, said thereafter with (d) water, equivalent weight reagents being such react 55% to 95% groups, water reacts all remaining imparting durable hydrophilicity stain release properties substrate treated therewith disclosed.
