Claims13
A method of treating a substrate, comprising applying a composition to at least part of a hard surface of a substrate, wherein the composition comprises a fluorinated compound and a phosphate ester;
- wherein the fluorinated compound corresponds to one of the following formulas:
- [(A)m-L]nR or (A)m[L-R]n
- wherein m is a value of 1 to 4, n is a value of 1 to 4, L represents a linking group, R is an aliphatic group and A is a fluorinated residue of the formula:
- wherein a has a value of 1 to 100, b has a value of 0 to 100 with the sum of a and b being at least 2, R1 and R2 each independently represent H or an alkyl group of 1 to 4 carbon atoms, Q and Q′ each independently represent a covalent bond or an organic linking group, Rf represents a fluoroaliphatic group, Rh represents a non-fluorinated group and X1 is H or the residue of a free radical initiator;
- wherein the phosphate ester corresponds to the general formula:
- wherein R1 and R2 each independently represent a hydrocarbon group of at least 6 carbon atoms, X represents a hydrocarbon linking group, z has a value of 1 to 5 and M represents a monovalent cation;
- and
- wherein the hard surface of the substrate is natural or man-made stone.
