This invention is directed to a composition capable of imparting surface effects to a liquid by contacting the liquid with a partially fluorinated phosphate with an ammonium cation (NHRR)wherein Rand Rare independently linear or branched organic groups containing at least one carboxylate moiety and one amino moiety, and optionally be substituted, interrupted, or both with oxygen, sulfur, or nitrogen-containing moieties, or with cyclic alkyl or aryl moieties containing up to 10 carbon atoms.

Fluorophosphate surfactants

This invention relates to a composition comprising a solvent-based fluoropolymer and its use as a coating additive, and a coating composition comprising the fluoropolymer. The coating composition comprising the solvent-based fluoropolymer provides desirable properties including uniform spreading, and cleanability and increased contact angle to a coated substrate. There is further provided a method of treating a substrate using the coating composition.

Solvent-based fluoropolymer additives and their use in coating compositions

Fluoropolymer additive for coatings

The present invention relates to a compound of formula (1), or mixtures thereof: wherein R, X, Y, A, p, m, n, r, q, x, M, R, R, Z, a, and Rare defined herein; wherein at least one of p or m is a positive integer; provided that, when q is 0, r is (3&#x2212;x), and when q is 1, r and x are each 1; provided that, if n is greater than 2, then p is 1; provided that, if m is 0 then Y is a single bond, and if m is a positive integer then Y is 0; and provided that when Ris greater than 8 carbons, the ratio of hetero atoms to carbon atoms is at least 1:2.
