Patent ID: 8304479

Claim:
A low VOC coating composition comprising: (a) at least one latex polymer; (b) water; and (c) at least one open time additive present during formulation of the coating composition in an amount effective to increase the open time of the coating composition to greater than about 4 minutes, the at least one open time additive having structural formula IIA: wherein R 1 , R 2 and R 3 are independently selected from the group consisting of: a C 1 -C 18 alkyl, hydroxyalkyl, cycloalkyl, aryl or aralkyl, —H, butyl, tert-butyl, isobutyl, wherein X is a divalent hydrocarbon radical comprising a linear or branched alkylene radical having from about 2 to 8 carbon atoms; wherein n is an integer of from 1 to 100; wherein R 5 is selected from the group consisting of —OH, —OCH 3 , —OC 2 H 5 , —OC 3 H 7 , —OC 4 H 9 , —OC 5 H 11 , —OC 6 H 13 , —Cl, —Br, —CN, Phosphonate (—PO 3 − M + ), Phosphate (PO 4 − M + ), Sulfate (SO 4 − M + ), Sulfonate (SO 3 − M + ), carboxylate (COO − M + ), a nonionic group, a C 1 -C 12 alkyl group, a C 1 -C 12 hydroxyalkyl group, a C 1 -C 12 cycloalkyl group, a C 1 -C 12 aryl group, a C 1 -C 12 aralkyl group and a quaternary ammonium ion, wherein M+ is a cation, wherein the open time additive is present in an amount greater than about 1% by weight of the polymer.
