Abstract

Described herein is a coated building panel that comprises a side surface that is textured and exhibits a white and/or color. The building panel comprising an upper surface opposite a lower surface and a side surface extending between the upper surface and the lower surface, a coating applied to the side surface, the coating comprising an inorganic particle having a disk shape and an ionic dispersant comprising an ionic group that are present on a repeating unit and the ionic dispersant comprising at least two of the repeating units.

First claim

What is claimed is:

1. A multi-functional coating composition suitable for coating a building panel, the coating composition comprising:
a liquid carrier; and
solids comprising:
an inorganic particle having a disk shape and an average particle size of about 1 μm to about 10 μm;
a polymeric binder;
an ionic dispersant comprising sodium polyacrylate; and
a non-ionic wetting agent;

wherein the inorganic particle having the disk shape is present in an amount ranging from 0.5 wt. % to about 10.0 wt. % based on the total weight of the solids;
wherein the non-ionic wetting agent comprises three aromatic groups;
wherein the coating composition has a solids content ranging from about 70 wt. % to about 90 wt. % based on the total weight of the coating composition; and
wherein the multi-functional coating composition has a viscosity ranging from about 7,000 cps to about 18,000 cps as measured at 10 RPM with a #4 spindle.

2. The multi-functional coating composition according to claim 1 , wherein the ionic dispersant is anionic.

3. The multi-functional coating composition according to claim 1 , wherein the polymeric binder is vinyl acrylic latex.

4. The multi-functional coating composition according to claim 1 , wherein the polymeric binder is present in an amount ranging from about 1 wt. % to about 40 wt. % based on the total weight of the multi-functional coating composition.

5. The multi-functional coating composition according to claim 1 , wherein the ionic dispersant is present in an amount ranging from about 0.01 wt. % to about 2.0 wt. % based on the total weight of the multi-functional coating composition.

6. The multi-functional coating composition according to claim 1 , wherein the non-ionic wetting agent comprises tristyrylphenol ethoxylate.

7. The multi-functional coating composition according to claim 1 , wherein the disk shape of the inorganic particle has an aspect ratio that ranges from about 2:1 to about 100:1.

8. The multi-functional coating composition according to claim 1 , wherein the disk shape of the inorganic particle has an area per unit of weight that ranges from about 5 m 2 /g to about 9 m 2 /g.

9. A multi-functional coating composition suitable for coating a building panel, the coating composition comprising:
a liquid carrier;
solids comprising:
an inorganic particle having a disk shape;
an anionic dispersant comprising sodium polyacrylate; and
a non-ionic wetting agent;
wherein the inorganic particle having the disk shape is present in an amount ranging from 0.5 wt. % to about 10.0 wt. % based on the total weight of the solids; and
wherein the non-ionic wetting agent comprises tristyrylphenol ethoxylate;
wherein the coating composition has a solids content ranging from about 70 wt. % to about 90 wt. % based on the total weight of the coating composition; and

wherein the multi-functional coating composition has a viscosity ranging from about 7,000 cps to about 18,000 cps as measured at 10 RPM with a #4 spindle.

10. The multi-functional coating composition according to claim 9 , wherein the coating composition further comprises a polymeric binder present in an amount ranging from about 1 wt. % to about 40 wt. % based on the total weight of the multi-functional coating composition.

11. The multi-functional coating composition according to claim 9 , wherein the anionic dispersant is present in an amount ranging from about 0.01 wt. % to about 2.0 wt. % based on the total weight of the multi-functional coating composition.

12. The multi-functional coating composition according to claim 9 , wherein the disk shape of the inorganic particle has an aspect ratio that ranges from about 2:1 to about 100:1.

13. A multi-functional coating composition suitable for coating a building panel, the coating composition comprising:
a liquid carrier;
solids comprising:
an inorganic particle having a disk shape and an average particle size of about 1 μm to about 10 μm, wherein the inorganic particle is present in an amount ranging from 0.5 wt. % to about 10.0 wt. % based on the total weight of the solids;
a polymeric binder; and
an anionic dispersant comprising sodium polyacrylate; and
a non-ionic wetting agent comprising tristyrylphenol ethoxylate;

wherein the coating composition has a solids content ranging from about 70 wt. % to about 95 wt. % based on the total weight of the coating composition; and
wherein the multi-functional coating composition has viscosity ranging from about 7,000 cps to about 18,000 cps as measured at 10 RPM with a spindle #4.
