Patent number: 9598594Abstract: 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.Type: GrantFiled: February 12, 2016Date of Patent: March 21, 2017Assignee: Valspar Sourcing, Inc.Inventors: Karl A.

Patent number: 9487670Abstract: 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.Type: GrantFiled: April 22, 2013Date of Patent: November 8, 2016Assignee: Valspar Sourcing, Inc.Inventors: Stephen M. Korenkiewicz, Karl A. Booth

Patent number: 9284467Abstract: 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.Type: GrantFiled: April 22, 2013Date of Patent: March 15, 2016Assignee: Valspar Sourcing, Inc.Inventors: Karl A.

Patent number: 8822580Abstract: 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.Type: GrantFiled: January 11, 2010Date of Patent: September 2, 2014Assignee: Valspar Sourcing, Inc.Inventors: Stephen M.
