Abstract
Fluoroalkyl phosphates containing a tertiary carbon and a nonfluorinated chain are useful as surfactants and additives. The f can be used to alter a surface property of a medium and to provide resistance to blocking, open time extension, or oil repellency to a substrate.
Claims14
A method of altering a surface property of a medium comprising adding to the medium a composition comprising one or more compounds of Formula I or Formula II:
- wherein x is 1 or 2, y is 1 or 2, x+y=3, and M is hydrogen, ammonium, alkali metal, or alkaline earth metal.
A method of providing resistance to blocking, open time extension, or 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 Formula II:
- wherein x is 1 or 2, y is 1 or 2, x+y=3, and M is hydrogen, ammonium, alkali metal, or alkaline earth metal.
