  • Publication number: 20090088516
    Abstract: A system and method to improve the color acceptance of color viscosity stabilized latex paints. The system includes a base paint, 0.05 wt % to 5 wt % of a color viscosity stabilizing compound; a colorant compound, and; a sufficient amount of a hydrophobically modified alkali swellable emulsion (“HASE”) thickener to improve the color acceptance properties of the paint, which amount is typically 0.02 wt % to 0.5 wt % of the paint, and optionally, 0.1 wt % to 5 wt % of a condensation polymer associative thickener including polyether polyurethanes, polyether polyols, polyether polyacetals, and polyether aminoplasts. The system demonstrates improved color acceptance as measured by rub-ups and ?E values.

  • Publication number: 20050209397
    Abstract: Printing inks have their performance improved by use of additives derived from rubber polyisoprenes “built-up” from rubber precursors or degraded using known techniques. A weight average molecular weight for the additives between 10,000-40,000 daltons has been found particularly effective and a loading between 1 and 10% optimum.

  • Patent number: 5973063
    Abstract: The present invention relates to improved thickening compositions, often referred to as Theological additives, used to provide viscosity control, flow, leveling and other rheological properties to clear aqueous systems such as automotive clear-coat paints and coatings. The invention hereof involves the synthesis of a new family of Theological additives by combining, through a reaction process, chemicals used to make specified polyurethane polymer compositions. These novel copolymers provides the good flow and leveling and gloss retention that polyurethane associative thickeners impart to water-based systems, without the loss of clarity that such polymers have caused in the past. Levels of the rheological thickening composition, varying between about 0.01% and about 10%, based on the total weight of the system to be thickened, have been found to be useful to create novel clear aqueous systems containing such thickening compositions.
