The present invention relates to a composition comprising a) an aqueous dispersion of polymer particles and b) a hydrophobically modified poly(oxyalkylene-urethane) rheology modifier having a 1) backbone; and 2) a hydrophobic portion represented by Fragment I: where R and Rare defined herein. The composition is useful as an aqueous coating formulation that exhibits a highly shear thinning rheology profile suitable for spray applications to provide high sag resistance without adverse impact on gloss or corrosion resistance.

Coating formulation with a poly(oxyalkylene-urethane) associative thickener modified with a hydrophobic oligomer

A waterborne sound and vibration damping composition including a waterborne emulsion polymer, the polymer having a calculated acid number of from 2 to 100; from 0.1% to 50%, solids based on emulsion polymer solids, of certain liquid compounds having a boiling point greater than 150&#xb0; C.; and a solid filler at a level of from 25% to 85% PVC; wherein the waterborne damping composition has a water content of from 6% to 25% by weight is provided. A method for providing a coated substrate using the waterborne damping composition and a substrate so coated are also provided.

Waterborne damping composition

The present invention relates to a deep base paint composition comprising a binder (an aqueous dispersion of polymer particles), an associative thickener with a hydrophobic portion having a calculated log P in the range of from 2.7 to 4.8. The composition of the present invention provides a mechanism for decreasing the viscosity sensitivity of a base paint to colorant addition.
