Abstract: The present invention relates to a composition comprising an aqueous solution of a hydrophobically modified alkylene oxide urethane polymer (HEUR), a bismuth salt, and at least one sediment abating compound selected from the group consisting of citric acid or a salt thereof, gluconic acid or a salt thereof, and a salt of ethylenediamine tetraacetic acid. The composition with the specific sediment abating compounds shows excellent abatement in sediment and color formation in heat age testing of the solution.

Abstract: The present invention is a composition comprising an aqueous admixture of a neutralized or partially neutralized aminosilane and an associative thickener, wherein the admixture has a pH of less than 10.2. The admixture is beneficial as an easy-to-use paint additive that provides stain removal, stain blocking, and corrosion resistance for coatings from low VOC paints.
