ABSTRACT:
Fluorourethane additives for water-dispersed coating compositions comprising the product of the reaction of 1) at least one diisocyanate, or polyisocyanate or a mixture of polyisocyanates containing at least three isocyanate groups per molecule, (2) at least one fluorochemical compound containing at least one Zerewitinoff hydrogen in an amount sufficient to react with 5% to 80% of the isocyanate groups in the diisocyanate or polyisocyanate, (3) at least one compound of the formula R.sub.10 --(R.sub.2).sub.k --YH in an amount sufficient to react with 5% to 80% of the isocyanate groups in the diisocyanate or polyisocyanate and wherein R.sub.10 is a C.sub.1 -C.sub.18 alkyl, C.sub.1 -C.sub.18 omega-alkenyl radical, or C.sub.1 -C.sub.18 omega-alkenoyl; R.sub.2 is --C.sub.n H.sub.2 same or different and are H or a C.sub.1 -C.sub.6 alkyl radical, n is 0 to 12, p is 1 to 50; Y is O, S, or N(R.sub.7) wherein R.sub.7 is H or C.sub.1 -C.sub.6 alkyl; and k is 0 or 1; and optionally (4) water in an amount sufficient to react with 5% to 60% of the isocyanate groups in the diisocyanate or polyisocyanate are disclosed.
