Abstract
Water-based compositions containing a low VOC coalescent, a latex or water-dispersible polymer, and a water-insoluble UV-VIS (preferably, ultraviolet) absorber.
Claims89
A water-based composition, comprising:
- a latex polymer;
- and
- one or more UV-VIS absorbers comprising methyl-o-benzoyl benzoate;
- wherein the composition includes no greater than 5 grams of total VOC per 100 grams polymer solids;
- wherein the water-based composition comprises up to 3.0 wt-% of the one or more UV-VIS absorbers, based on the weight of polymer solids.
2 more elements
A water-based composition, comprising:
- a latex polymer having at least one Tg within a range of −10° C. to 30° C.;
- and
- methyl-o-benzoyl benzoate;
- wherein the composition includes no greater than 5 grams of total VOC per 100 grams polymer solids;
- and wherein
- the composition includes up to 3.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of polymer solids.
3 more elements
A water-based composition, comprising:
- a latex polymer having at least one Tg within a range of −10° C. to 30° C., wherein the latex polymer comprises the polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM);
- and
- methyl-o-benzoyl benzoate;
- wherein the composition includes no greater than 5 grams of total VOC per 100 grams polymer solids;
- and wherein
- the composition includes up to 3.0 wt-% of methyl-o-benzoyl benzoate, based on the weight of polymer solids.
3 more elements
A water-based composition, comprising:
- a latex polymer having at least one Tg within a range of −10° C. to 30° C., wherein the latex polymer comprises the polymerization product of ethylenically unsaturated monomers comprising acetoacetyl ethyl methacrylate (AAEM), butyl acrylate, and methyl methacrylate;
- and
- methyl-o-benzoyl benzoate;
- wherein the composition includes no greater than 5 grams of total VOC per 100 grams polymer solids;
- wherein
- the composition includes a sufficient amount of methyl-o-benzoyl benzoate to improve dirt pick-up resistance by at least 10%, relative to the same water-based composition without the methyl-o-benzoyl benzoate, based on a change in ΔE value;
- and wherein
- the composition includes to 3.0 wt.-% of methyl-o-benzoyl benzoate, based on the weight of polymer solids.
