Abstract

A paint composition, which in some embodiments, has a low odor in the container, while during after application to a surface, and once the paint has dried on a surface is disclosed. A method of making such a paint composition is disclosed. A paint composition and method are also disclosed which include using a paint to control certain odors in interior rooms.

Claims

1. A paint composition comprising:

a binder;

water; and

sodium bicarbonate, wherein at least some solid sodium bicarbonate is dispersed in the paint composition.

2. The paint composition of claim 1, wherein the sodium bicarbonate comprises about 3.2% to about 33% of the latex paint composition.

3. The paint composition of claim 1, further comprising:

and an odor entrapping agent selected from zeolite, cyclodextrin, activated carbon, anatase titanium dioxide, nano zinc oxide, undecylenic acid, salts of undecylenic acid, esters of undecylenic acid, and undecylenate silicone esters, chloramine-T, and zinc ricinolate, and combinations thereof.

4. A paint composition comprising:

a binder;

water;

sodium bicarbonate, wherein the sodium bicarbonate is present at the maximum level possible for the paint to remain a stable dispersion for application.

5. The paint composition of claim 4, further comprising:

and an odor entrapping agent selected from zeolite, cyclodextrin, activated carbon, anatase titanium dioxide, nano zinc oxide, undecylenic acid, salts of undecylenic acid, esters of undecylenic acid, and undecylenate silicone esters, chloramine-T, zinc ricinolate, and combinations thereof.

6. The paint composition of claim 4, further comprising:

a re-odorant composition.

7. A paint composition comprising:

a binder;

water;

a cyclodextrin; and

a zeolite.

8. The paint composition of claim 7, further comprising:

sodium bicarbonate.

9. The paint composition of claim 8 wherein the paint composition comprises about 0.25 to about 40% by weight sodium bicarbonate.

10. The paint composition of claim 7 wherein the paint composition comprises about 2% to about 5% zeolite.

11. The paint composition of claim 7 wherein the paint composition comprises about 1% to about 3% cyclodextrin.

12. The paint composition of claim 7 wherein the cyclodextrin and zeolite combined comprise up to about 20% by weight of the paint composition.

13. The paint composition of claim 7, further comprising:

a reodorant.

14. A paint composition capable of reducing odors in an interior room, said paint composition comprising:

a binder;

water; and

an odor neutralizing agent selected from undecylenic acid, salts of undecylenic acid, esters of undecylenic acid, and undecylenate silicone esters, and combinations thereof.

15. A process for reducing an odor emitted by aqueous latex-based coating material comprising adding to the coating material during or after its manufacture sodium bicarbonate.

16. The process of claim 15 wherein the odor reduced is the odor emitted prior to application of the coating material to a substrate.

17. The process of claim 15 wherein the odor reduced is the odor emitted as the coating material dries after application to a substrate.

18. The process of claim 15 wherein the odor reduced is the odor emitted by the coating material after it has dried on a substrate.

19. The process of claim 15, wherein the sodium bicarbonate is added to a grind paste used to prepare the coating material.

20. The process of claim 15, wherein the sodium bicarbonate is post-added to a finished paint composition.

21. A process for reducing odors in an interior room comprising:

applying a latex-based paint to one or more walls of said interior room, said paint comprising;

a binder, water, zeolite, and cyclodextrin; and

allowing said paint to dry.

22. The process of claim 21, wherein said latex-based paint further comprises sodium bicarbonate.

23. The process of claim 22, wherein said paint composition comprises up to about 40% by weight sodium bicarbonate.

24. A process for preventing rust formation comprising:

applying a paint composition comprising a binder, water, and sodium bicarbonate to a metal surface; and

allowing said paint to dry.

25. The process of claim 24 wherein the paint composition comprises about 0.5% to about 8% by weight sodium bicarbonate.

26. A process for preventing the growth of bacteria on surfaces comprising:

applying a paint composition comprising a binder, water, and sodium bicarbonate to a surface; and

allowing said paint to dry.

27. The process of claim 26 wherein the paint composition further comprises a dry film preservative selected from carbendazim, chlorothalonil, 3-iodo-2-propynyl butyl carbamate (IPBC), 1,2-benzisothaiazolin-3-one (BIT), sodium omadine, zinc omadine, zinc oxide, tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione solution, 5-hydroxymethoxymethyl-1-AZA-3,7-dioxabicyclo[3.3.0]octane formaldehyde release type preservative, 2-n-octyl-4-isothiazolin-3-one, 1 -(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride.

28. A dry paint film comprising:

a cyclodextrin; and

a zeolite.

29. The dry paint film of claim 28, further comprising:

sodium bicarbonate.

30. A dry paint film comprising:

about 0.5% to about 17.3% by weight sodium bicarbonate.

31. A method of manufacturing paint comprising:

preparing a grind paste comprising a latex binder, water, pigment, sodium bicarbonate, wherein the pH of the paint is about 9.2.
