PIGMENTED PAINT FORMULATION WITH A PHOSPHORUS ACID FUNCTIONALIZED LATEX BINDER AND AN ASSOCIATIVE THICKENER

摘要

The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 4.8; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiO 2 particles. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.
