VOC and odor reducing building panels
Described herein is a building panel comprising a substrate and an odor and VOC reducing coating applied to the substrate, the coating comprising a blend of a first component comprising ethylene urea; a second component comprising silica; and a rheology modifier.
1. A VOC and odor-reducing building panel comprising:
a substrate; and
a coating applied to the substrate, the coating comprising:
silica gel;
a surfactant; and
a rheology modifier.
2. The building panel according to claim 1 , wherein the coating is solid at room temperature and comprises less than about 5 wt. % of a carrier based on the total weight of the coating, the carrier selected from water.
3. The building panel according to claim 1 , wherein the silica gel is present in an amount ranging from about 5 wt. % to about 40 wt. % based on the total weight of the coating.
4. The building panel according to claim 1 , wherein the coating is present on the substrate in an amount ranging from about 50 g/m 2 to about 400 g/m 2 .
5. The building panel according to claim 1 , wherein the coating exhibits substantially the same odor-reducing performance in an environment having 90% relative humidity as an environment having at 0% relative humidity.
6. The building panel according to claim 1 , wherein the rheology modifier selected from silicate mineral, alkali-swellable compounds, and combinations thereof.
7. The building panel according to claim 6 , wherein the rheology modifier is present in an amount ranging from about 0.1 wt. % to about 55 wt. % based on the total weight of the coating.
8. A building panel comprising:
a substrate; and
a coating applied to the substrate, the coating comprising a blend of silica gel and kaolin.
9. The building panel according to claim 8 , wherein the coating is solid at room temperature and comprises less than about 5 wt. % of a carrier based on the total weight of the coating, the carrier selected from water.
10. The building panel according to claim 8 , wherein the silica gel is present in an amount ranging from about 5 wt. % to about 40 wt. % based on the total weight of the coating.
11. The building panel according to claim 8 , wherein the coating is present on the substrate in an amount ranging from about 50 g/m 2 to about 400 g/m 2 .
12. The building panel according to claim 8 , wherein the kaolin is present in an amount ranging from about 1 wt. % to about 55 wt. % based on the total weight of the coating.
13. The building panel according to claim 8 , wherein the kaolin particles have an average particle size ranging from about 0.5 μm to about 30 μm.
14. The building panel according to claim 8 , wherein the blend further comprises a surfactant.
15. A building panel comprising:
a substrate; and
a coating applied to the substrate, the coating comprising:
silica gel;
a surfactant blend comprising a first surfactant and a second surfactant; and
a rheology modifier;
wherein the first surfactant is non-ionic and the second surfactant is ionic.
16. The building panel according to claim 15 , wherein the coating is solid at room temperature and comprises less than about 5 wt. % of a carrier based on the total weight of the coating, the carrier selected from water.
17. The building panel according to claim 15 , wherein the silica gel is present in an amount ranging from about 5 wt. % to about 40 wt. % based on the total weight of the coating.
18. The building panel according to claim 15 , wherein the coating is present on the substrate in an amount ranging from about 50 g/m 2 to about 400 g/m 2 .
19. The building panel according to claim 15 , wherein the rheology modifier selected from silicate mineral, alkali-swellable compounds, and combinations thereof.
20. The building panel according to claim 15 , wherein the rheology modifier is present in an amount ranging from about 0.1 wt. % to about 55 wt. % based on the total weight of the coating.
