Claims21
1-20. (canceled)
A low-VOC paint, comprising:
- a latex polymer comprising a surfactant and polymer particles comprising a homopolymer or copolymer including at least one of an acrylate or a methacrylate;
- a pigment;
- and
- a coalescent having the formula:
- R1—(C(O)—O)—R2
- wherein:
- R1 is an aromatic group having 3 to 24 carbon atoms:-and
- R2 is a hydrocarbyl moiety having 3 to 24 carbon atoms;
- with the proviso that R1 and R2 together do not include any aliphatic unsaturated carbon-carbon bonds;
- wherein the coalescent has a volatile organic content of no greater than 50 wt-%;
- and
- wherein the total VOC in the paint is no greater than 15 grams per 100 grams polymer solids.
