Abstract

A protective coating composition comprises (a) a first component comprising one or more epoxy-terminated silane compounds, (b) a second component comprising one or more fluorochemical silane compounds, and (c) cationic photoinitiator. The first component comprises at least about 50% by weight of the composition.

Claims

1. A protective coating composition comprising:

a first component comprising one or more epoxy-terminated silane compounds;

a second component comprising one or more fluorochemical silane compounds; and

cationic photoinitiator;

wherein the first component comprises at least about 50% by weight of the composition.

2. The protective coating composition of claim 1 further comprising one or more diepoxide compounds.

4. The protective coating composition of claim 1 wherein the second component comprises from about 0.01% to about 10% by weight of the composition.

6. The protective coating composition of claim 1 wherein the first component comprises gamma-glycidoxypropyltrimethoxysilane.

7. The protective coating composition of claim 1 wherein the second component comprises perfluorinated polyether silane.

10. A decorative laminate comprising:

a decorative layer,

a protective overlayer comprising the protective coating composition of claim 1 or claim 8 atop the decorative layer.

11. The decorative laminate of claim 10 wherein the decorative layer comprises melamine resin.

12. The decorative laminate of claim 10 wherein there is a visible reduction in reflectance off the protective layer as compared to the decorative layer.

13. A decorative laminate comprising:

a decorative layer,

a wear layer atop the decorative layer, and

a protective overlayer comprising the protective coating composition of claim 1 or claim 8 atop the wear layer.

14. The decorative laminate of claim 13 wherein the wear layer comprises melamine resin.

15. The decorative laminate of claim 13 wherein there is a visible reduction in reflectance off the protective layer as compared to the wear layer.

23. A method for making a decorative laminate comprising:

providing a decorative article comprising a decorative layer;

coating the protective coating composition of claim 1 on the decorative layer;

curing the protective coating composition using ultraviolet light; and

laminating the decorative article using heat and pressure.

24. The method of claim 23 wherein the decorative layer comprises melamine resin.

25. A method for making a decorative laminate comprising:

providing a decorative article comprising (i) a decorative layer and (ii) a wear layer atop the decorative layer;

coating the protective coating composition of claim 1 on the wear layer;

curing the protective coating composition using ultraviolet light; and

laminating the decorative article using heat and pressure.

26. The method of claim 25 wherein the wear layer comprises melamine resin.

21. A protective coating composition comprising:

a first component comprising one or more epoxy-terminated silane compounds;

a second component comprising one or more perfluorinated ether-containing alcohols; and

cationic photoinitiator;

wherein the first component comprises at least about 50% by weight of the composition.

22. (canceled)

27. (canceled)

28. A decorative laminate comprising:

an underlayer comprising melamine resin, and

a protective overlayer comprising a protective coating comprising the reaction product of (i) one or more epoxy-terminated silane compounds, and (ii) cationic photoinitiator.

29. A method for making a decorative laminate comprising:

providing a decorative article comprising an underlayer comprising melamine resin;

coating a protective coating composition comprising (i) one or more epoxy-terminated silane compounds, and (ii) cationic photoinitiator on the underlayer;

curing the protective coating composition using UV light; and

laminating the decorative article using heat and pressure.
