Abstract

Claims (28)

1. A latex-based paint comprising:

a latex polymer, wherein the latex polymer is not a multi-stage latex polymer; and

methyl-o-benzoyl benzoate;

wherein the paint includes no greater than 50 grams of total VOC per 100 grams polymer solids; and

wherein the paint has a pigment volume concentration range of 20 to 75.

2. The paint of claim 1 wherein the paint includes no greater than 25 grams of total VOC per 100 grams polymer solids.

3. The paint of claim 2 wherein the paint includes no greater than 20 grams of total VOC per 100 grams polymer solids.

4. The paint of claim 3 wherein the paint includes no greater than 10 grams of total VOC per 100 grams polymer solids.

5. The paint of claim 4 wherein the latex polymer comprises a polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM), diacetone acrylamide, or mixtures thereof.

6. The paint of claim 4 wherein the latex polymer comprises a polymerization product of ethylenically unsaturated monomers that do not include styrene.

7. The paint of claim 4 wherein the latex polymer comprises a surfactant and polymer particles comprising a copolymer including at least one of an acrylate or a methacrylate.

8. The paint of claim 4 comprising at least 0.1 wt-% and up to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids.

9. The paint of claim 1 comprising at least 0.1 wt-% and up to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids.

10. The paint of claim 1 further comprising a defoamer and at least one of a mildewcide or a biocide.

11. The paint of claim 1 further comprising a pigment, a defoamer, a thickener, a surfactant, a dispersant, a filler, and combinations thereof.

12. The paint of claim 1 further comprising a surfactant.

13. The paint of claim 12 wherein the surfactant comprises sodium laureth sulfate.

14. The paint of claim 1 comprising sufficient TiO 2 pigment to be substantially visually opaque when applied at a thickness of 3 mils (0.0762 mm) and dried.

15. The paint of claim 14 which has a minimum film forming temperature of less than 25° C.

16. The paint of claim 1 which does not include a water-dispersible polymer selected from the group of a polyurethane, an epoxy, a polyamide, a chlorinated polyolefin, a polyester, and a mixture or copolymer thereof.

17. A latex-based paint comprising:

a latex polymer comprising a copolymer including at least one of an acrylate or a methacrylate, wherein the latex polymer is not a multi-stage latex polymer;

0.1 wt-% to 5.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of the polymer solids; and

one or more of a pigment, a defoamer, a thickener, a surfactant, a dispersant, and a filler;

wherein the paint includes no greater than 50 grams of total VOC per 100 grams polymer solids; and

wherein the paint has a pigment volume concentration range of 20 to 75.

18. The paint of claim 17 wherein the latex polymer comprises a polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM), diacetone acrylamide, or mixtures thereof.

19. The paint of claim 17 which has a minimum film forming temperature of less than 25° C.
