  • Publication number: 20120160870
    Abstract: White-pigmented and unpigmented base paints and stains are custom-tinted using an automated colorant dispenser having a minimum fluid dispensing quantity less than 0.01 fluid ounce (<0.3 cm3) and an array of colorants including a green-hued colorant having a color strength greater than that of a comparison colorant containing 12 wt. % PG7 pigment, a blue-hued colorant having a color strength greater than that of a comparison colorant containing 7 wt. % PB15:2 pigment, and a red-hued colorant having a color strength greater than that of a comparison colorant containing 17 wt. % PR209 pigment. The green-hued or blue-hued colorants are dispensed into the base paint or stain whenever a green-hued or blue-hued tint is required. Light pastel tints in small containers and strong colors in large containers may be prepared without requiring the use of additional colorants having the same general hue and lower color strength.

  • Publication number: 20100113685
    Abstract: A universal colorant system for both solvent- and water-based paints and coatings is contained in a closed sealed pouch or cartridge-style container, and includes a colorant component, a surfactant package including at least one alkyd-compatible surfactant and at least one latex-compatible surfactant, and a carrier. When the colorant system is added to a base paint it desirably provides a mixture having a drop in viscosity of less than about 50%.

  • Patent number: 7659340
    Abstract: A universal colorant composition for both solvent- and water-based paints and coatings 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 a carrier. 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: 4844952
    Abstract: A method of forming a multilayered finish on a substrate involves:I. applying a decorative finish to a substrate:II. applying a clear, aqueous based coating composition over the decorative finish of step I, said clear coating composition containing:(a) a waterborne polymer having calculated a glass transition temperature of at least about 40.degree. C. and having a one component working parameter of solubility, .delta. wp, in the range of about 9.0 to about 9.6 (cal./cm.sup.3).sup.1/2, with ##EQU1##whereinFi=the molar attraction constant of an individual functional group of the polymer expressed in cal..sup.1/2 cm.sup.3/2 /mole, andVi=the molar volume constant of an individual group of the polymer expressed in cubic cubic centimeters per mole; and(b) an amount of coalescing component sufficient to form a coalesced film, said clearcoating composition being essentially free of external crosslinking agents; andIII. allowing the coating composition to coalesce.
