Patent ID: 8444758

Claim:
An additive composition for extending the open-time of an aqueous composition comprising a) from about 30 to about 65 weight percent of a water-dispersible polymer, based on the total weight of solids in said additive, said water-dispersible polymer having a Tg in the range of from about 20° C. to about 160° C., b) from about 5 to about 40 weight percent of a water-insoluble plasticizer, based on the total weight of solids in said additive, said water-insoluble plasticizer having a molecular weight of less than about 1,000 g/mole and comprises an ester of a glycol, a triol, and/or a polyol; an ester of monofunctional aromatic carboxylic acid and a monofunctional alcohol; an ester of a dicarboxylic acid and/or a tricarboxylic acid; an ether of a glycol, or a triol, and/or a polyol; or mixtures thereof; and c) from about 30 to about 65 weight percent cyclohexanedimethanol, based on the total weight of solids in said additive, wherein said additive composition is an aqueous dispersion and has a VOC content of less than about 20 weight percent based on the total weight of said additive.
