Abstract

Compositions include a water-soluble copolymer, a hydrophilic silane compound, and in some embodiments surfactant dispersed in a liquid phase. Methods of using the compositions to coat and optionally clean a substrate are also disclosed.

First claim

What is claimed is:

1. A composition comprising:
a liquid phase;
a water-soluble copolymer of an ethylenically unsaturated acidic monomer and an ethylenically unsaturated monomer comprising a nitrogen-containing terminal group, or salt thereof; and
a hydrophilic zwitterionic silane component;
wherein the composition is absent of silica nanoparticles.

2. The composition of claim 1 wherein the ethylenically unsaturated monomer comprising a nitrogen-containing terminal group is acrylamide represented by the formula

wherein R 4 is H or methyl; and
R 1 and R 2 are independently selected from H; C 1 -C 3 alkyl; or R 3 SO 3 H, wherein R 3 is alkylene having from 2 to 6 carbon atoms.

3. The composition of claim 2 wherein the water-soluble copolymer has the general formula

wherein R 4 is H or methyl;
R 1 and R 2 are independently selected from H; C 1 -C 3 alkyl; —CH 2 OH, or R 3 SO 3 H, wherein R 3 is alkylene having from 2 to 6 carbon atoms; and
M + is a cation.

4. The composition of claim 1 wherein the ethylenically unsaturated monomer comprising a nitrogen-containing terminal group comprises a quaternized ammonium terminal group and is represented by the formula

wherein R 4 is H or methyl;
L is a divalent atom or linking group;
R 5 , R 6 , and R 7 are independently selected from C 1 -C 4 alkyl; and
X − is an anion.

5. The composition of claim 4 wherein the water-soluble copolymer has the general formula

wherein R 4 is H or methyl;
L is a divalent atom or linking group;
R 5 , R 6 , and R 7 are independently selected from C 1 -C 4 alkyl;
X − is an anion; and
M + is a cation.

6. The composition of claim 1 wherein the water-soluble copolymer has a weight ratio of ethylenically unsaturated acidic monomer to ethylenically unsaturated monomer comprising a nitrogen-containing terminal group in a range of from 5:95 to 95:5.

7. The composition of claim 1 wherein the liquid carrier comprises at least 50 percent by weight water.

8. The composition of claim 1 wherein the hydrophilic zwitterionic silane component is present in an amount ranging from 5 to 50 weight % solids.

9. The composition of claim 1 wherein the composition further comprises a sulfonate-functional silane.

10. The composition of claim 1 wherein the hydrophilic zwitterionic silane is a sulfonate-functional zwitterionic silane.

11. The composition of claim 1 wherein the composition further comprises surfactant.

12. The composition of claim 11 wherein the composition comprises nonionic surfactant and anionic surfactant.

13. The composition of claim 1 wherein the composition comprises an alkyl polysaccharide nonionic surfactant.

14. The composition of claim 1 further comprising a preservative, an alkali metal silicate, silica nanoparticles, or a combination thereof.

15. A method of protecting and optionally cleaning an article, the method comprising applying the composition of claim 1 to a surface of a substrate and at least partially removing the aqueous liquid phase from the surface of the substrate.

16. The method of claim 15 further comprising rubbing the composition on the surface.

17. The method of claim 15 wherein the surface comprises at least one of glass, metal, ceramic, wood, or an organic polymeric material.

18. The method of claim 15 wherein the substrate is selected from the group consisting of shower surrounds, bathtubs, toilets, sinks, faucets, windows, mirrors, appliances, and countertops.

19. An article comprising a coating comprising the dried composition of claim 1 .
