Abstract:
The present invention relates to a composition comprising an aqueous dispersion of acrylic based polymer particles; less than 15 PVC of a pigment; and a hydrophobically modified poly(oxyalkylene-urethane) rheology modifier having a hydrophobic portion represented by Structure I: Where R, R1, R2, m an n are defined herein. The composition provides viscosity stability for paint formulations containing a HEUR rheology modifier.
