Low molecular weight non-film forming fluorinated polyurethanes having a hydroxy functionality obtained from the reaction of at least one diisocyanate with at least one hydroxy-capped perfluoropolyether having a molecular weight within the range of from greater than 1,000 to 5,000 and with at least one polyol with a functionality of at least 2.

Fluorinated polyurethanes with hydroxy functionality, process for

Water-dilutable fluorinated polyurethanes obtained from the reaction of at least one diisocyanate with at least one hydroxy-capped perfluoropolyether having a molecular weight comprised within the range of from 400 to 7000 with at least one polyol with a hydroxy functionality higher than, or equal to, 2, supporting at least one ionizable group and therefore with at least one hydroxy compound with a functionality of at least 1. Use of these products in the treatment of lithoidal products.

Water-dilutable fluorinated polyurethanes, process for preparing them

Aqueous dispersions of urethane-acrylic polymers, giving coatings resistant to alkalies and organic solvents, are obtained by starting from organic polyisocyanates and mixtures consisting of macroglycols and polyols containing ionizable groups and at least one ethylenic unsaturation.
