Abstract
Water-based compositions containing a low VOC coalescent, a latex or water-dispersible polymer are described.
Claims20
A low VOC paint, comprising:
- a latex polymer comprising a surfactant and polymer particles comprising a homopolymer or copolymer and including at least one of an acrylate or a methacrylate;
- methyl-o-benzoyl benzoate;
- a pigment;
- and
- at least one coalescent;
- wherein the coalescent has a volatile organic content of less than about 15 wt %, is nonreactive in the paint, and is dispersible in the paint to form a uniform mixture;
- and wherein the paint contains sufficient TiO2 pigment to be substantially visually opaque when applied at a thickness of 3 mil (0.0762 mm) and dried;
- and wherein the paint includes no greater than 5 grams of total VOC per 100 grams polymer solids.
