  • Patent number: 10676623
    Abstract: A coating composition including about 5 wt % to about 70 wt % of a latex or a water-dispersible film forming polymer, based on the total weight of the coating composition, a surfactant present in the coating composition at 0.1% to about 1% on the continuous phase of the coating composition; a polymeric associative thickener present in the coating composition at about 0.1% to about 2% on the continuous phase of the coating composition; about 0.1 wt % to about 5 wt % a styrene acrylic resin, based on the total weight of the coating composition; and an aqueous diluent.
    Type: Grant

  • Publication number: 20060207476
    Abstract: A universal colorant composition for both solvent- and water-based paints and coatings. The universal colorant composition is a composition which includes a colorant component, such as pigment, dye, colorant, tinting agent and/or metal effect agent; a surfactant package including at least one alkyd-compatible surfactant; and at least one latex-compatible surfactant; and when the surfactant package is added to a base paint it provides a mixture having a drop in viscosity of less than about 50%.

  • Patent number: 6488760
    Abstract: A universal tinting concentrate for both solvent- and water-based paints and coatings. The universal tinting concentrate is a composition which includes a colorant component, such as pigment, colorant, tinting agent and/or metal effect agent; a pigment dispersant including a moiety selected from the group consisting of an organic acid, anhydride, salt thereof, and derivative thereof, wherein the dispersant facilitates the dispersal of the colorant component in organic-based and aqueous-based vehicles; and a pH-neutralizing agent. In one embodiment of the invention, the pigment dispersant is represented by the following structure: where r and s are integers and r+s is 6 to 16; x and y are integers and x+y is 0 to 19; Z is H or COOH; and Z′ is H or COOH.

  • Patent number: 6287377
    Abstract: A universal tinting concentrate for both solvent- and water-based paints and coatings. The universal tinting concentrate is a composition which includes a colorant component, such as pigment, colorant, tinting agent and/or metal effect agent; a pigment dispersant including an organic acid containing no more an 70 carbon atoms; and a pH-neutralizing agent. In one embodiment of the invention, the pigment dispersant is represented by the following structure: where r and s are integers and r+s is 6 to 16; and x and y are integers and x+y is 0 to 19; and Z is H or COOH and Z′ is H or COOH.
