Reactive liquids diluent and reactive dispersing agents for fluid concentrates, colorants and coating compositions, wherein the reactive liquid diluent and reactive dispersing agents have a viscosity less than 1,000 cps and contain at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent or dispersing agent may be included a coating composition to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder.

Pigment dispersion

Fluid concentrates, colorants and coating compositions contain solid pigment particles dispersed in a nonvolatilizing, reactive liquid diluent having a viscosity less than 1,000 cps and containing at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent may serve as one or more of a dispersing medium for the solid pigment particles, a carrier, a coalescent and a humectant, and may crosslink or otherwise cure to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder. Embodiments of the reactive liquid diluent can provide colorants and coating compositions having reduced levels of VOCs, conventional carriers, conventional dispersants, conventional coalescents and conventional humectants.

The present disclosure refers to an aqueous stain resistant coating composition, comprising, one or more aqueous dispersions of self-crosslinkable polymeric particles; and one or more particulate solids, wherein the polymeric particles have a Tg of 10&#xb0; C. or less; and wherein the particulate solids comprise a combination of sheet-like particulate solids and sphere-like particulate solids in a weight ratio of 1:1 or more; and wherein the coating composition has a pigment volume concentration of 45% or more; and the coating composition is substantially free of volatile organic compounds.

Aqueous stain resistant coating composition

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.

Waterborne latex coating compositions with viscosity-modifying coalescence aids

A pigment grind dispersion contains non-adsorbed titanium dioxide particles dispersed in an aqueous emulsion containing a mixture of (a) water-insoluble film-forming first polymer particles that adsorb to titanium dioxide particles, the first polymer particle amount in the emulsion being less than the saturation level of adsorption when another polymer is not present, (b) water-insoluble film-forming second polymer particles that do not by themselves form composite particles with titanium dioxide particles, the second polymer particle amount in the emulsion being sufficient to inhibit or interfere with adsorption of the first polymer particles to titanium dioxide particles, and (c) extender particles. The pigment grind dispersion has a titanium dioxide pigment volume concentration of about 25 to about 50 and a titania composite ratio of about 32 to about 60.

Titanium dioxide pigment grind dispersion and paint

Titanium dioxide may be more efficiently used in a coating composition containing a composite pigment particle-forming polymer if during composite formation, the polymer is initially present in a low concentration and the titanium dioxide particles and newly-formed composite particles are dispersed in a waterborne emulsion polymer that does not form such a composite. A pigment grind dispersion of titanium dioxide pigment-polymer composite particles may be made by mixing titanium dioxide particles with the waterborne emulsion polymer. The composite-forming polymer is then added to the waterborne emulsion polymer, or is added independently and concurrently with the titanium dioxide particles. The resulting titanium dioxide pigment-polymer composite particles provide improved coating composition opacity compared to a coating composition that does not contain such composite particles. The coating compositions can contain reduced titanium dioxide amounts and less than a saturation level of the composite-forming polymer.

Method for making titanium dioxide pigment grind dispersion and paint

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 (&#x3c;0.3 cm) and a set 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 12 wt. % PB15:2 pigment, a red-hued colorant having a color strength greater than that of a comparison colorant containing 17 wt. % PR209 pigment and a magenta-hued colorant having a color strength greater than that of a comparison magenta-hued colorant containing 7 wt. % PR122 pigment. 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.

Expanded color space architectural paint and stain tinting system

A pigment grind dispersion of titanium dioxide pigment-polymer composite particles is made by mixing titanium dioxide particles with an aqueous emulsion containing (i) less than a saturation level amount of water-insoluble film-forming first polymer particles that adsorb to the titanium dioxide particles, and (ii) an inhibiting or interfering amount of water-insoluble film-forming second polymer particles that do not adsorb to the titanium dioxide particles, wherein the pigment grind dispersion has a titanium dioxide pigment volume concentration of about 25 to about 50 and a titanic composite ratio of about 32 to about 60. The resulting titanium dioxide pigment-polymer composite particles can provide improved coating composition opacity compared to a coating composition that does not contain such composite particles, can employ reduced titanium dioxide amounts and less than a saturation level of the first polymer, and can provide improved storage stability.

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 (&#x3c;0.3 cm) 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.

Custom-tinted paints and stains are made using an array of low VOC concentrated liquid colorants including at least at least white colorant; black colorant; and green-hued, blue-hued and red-hued primary colorants at least one of which primary colorants comprises polyalkylene glycol humectant, ethoxylated surfactant and extender pigment. For colorants in the array containing polyalkylene glycol humectant, the humectant and ethoxylated surfactant amounts are sufficiently high and extender pigment amount is sufficiently low so that the colorants will not problematically plug colorant dispenser orifices if left in the dispenser without an orifice cap for a full day. The polyalkylene glycol humectant is also present in an amount sufficiently low so that dried paint films made by mixing the colorants with a clear waterborne base paint will resist blocking.

Architectural paint and stain tinting system with tip drying resistance

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%.
