Copolymers and latex paint compositions using such copolymers that are heat-age stable and provide good adhesion, block resistance, and hiding all while using lower amounts of titanium dioxide are described herein. In one aspect, the heat-age stable compositions include an acrylic, styrene acrylic, vinyl acrylic copolymer or blends thereof including, as additional polymerizable units, at least one polymerizable phosphate surfactant and at least one linear or branched hydrophobic monomer that are both polymerized into the acrylic, styrene acrylic, vinyl acrylic copolymer backbone.

Water borne coating compositions and polymers therefor

This invention relates to polyurethane thickeners having particular utility in paints and coatings comprising the reaction product of an isocyanate functional material, a polyether polyol, and a difunctional hydrophilic endcapping material that is reactive with isocyanates.

Hydrophilically end-capped polyurethane thickeners

Low VOC penetrating compositions for staining and protecting porous substrates such as wood, concrete, cement, brick and the like, comprising aqueous dispersions of polyurethane-ureas.

Penetrating stains and sealants from polyurethane dispersions

A process for producing a coating compositions having superior solvent resistance and film hardness comprising an interpenetrating network of a polyurethane component and a functionalized waterborne polymer, wherein the polyurethane component is prepared in the presence of the functionalized waterborne polymer and said polyurethane component and said waterborne polymer are crosslinked directly or indirectly via the chain extender.

Interpenetrating networks of polymers

A process for producing a coating compositions for use over chalky substrates comprising a partial interpenetrating network of a polyurethane component and a waterborne polymer component, wherein the polyurethane component is prepared in the presence of the waterborne polymer component.

Partial interpenetrating networks of polymers

Low VOC compositions for coating, staining and protecting porous substrates such as wood, concrete, cement, brick and the like, comprising aqueous dispersions of polyurethane-ureas.
