More Information
Summary:The present invention relates to a composition comprising a hydrophobically modified alkylene oxide polymer having a hydrophobic portion characterized by the following group:where R1 and x are as defined herein; and a) an aqueous dispersion of thermoplastic polymer particles imbibed with a thermosettable compound functionalized with structural units of an anti-agglomerating monomer; and/or b) a curing agent. The composition of the present invention is useful for improving Brookfield viscosity and sag resistance in coatings arising from, for example, 2-component acrylic-epoxy hybrid systems cured with a curing agent.
