Abstract
The rheological properties of latexes and latex paint formulations thickened with non-urethane thickeners according to the invention are modified by adding to the latex or latex paint formulation an amount of a nonionic surfactant having an HLB value of from 4 to about 20 sufficient to decrease the low shear viscosity of the thickened latex without a corresponding reduction in the high shear viscosity.
