Fluoroalkyl phosphate compositions
View Patent ↗A composition comprising a compound of formula (I) or (II): wherein r and q are independently integers of 1 to 3; R f is linear or branched chain perfluoroalkyl group having 1 to 6 carbon atoms; j is an integer 0 or 1, or a mixture thereof, x is 1 or 2, Z is —O— or —S—, X is hydrogen or M, and M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion is disclosed.
1. A method of providing resistance to blocking, open time extension and oil repellency to a substrate having deposited thereon a coating composition comprising adding to the coating composition, prior to deposition on the substrate, a composition comprising one or more compounds of formula (I) or (II):
wherein
r and q are independently integers of 1 to 3;
R f is linear or branched chain perfluoroalkyl group having 1 to 6 carbon atoms;
j is an integer 0 or 1, or a mixture thereof,
x is 1 or 2,
Z is —O— or —S—,
X is hydrogen or M, and
M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion.
2. The method of claim 1 wherein the coating composition is a water dispersed coating, alkyd coating, Type I urethane coating, or unsaturated polyester coating.
3. The method of claim 1 wherein R f has 4 to 6 carbon atoms, and r, q and j are each 1.
4. The method of claim 1 wherein M is an ammonium or an alkanolammonium ion.
5. A substrate treated according to the method of claim 1 .
