  • Patent number: 9701842
    Abstract: The disclosure provides a process for preparing a self-dispersing pigment having an isoelectric point of at least about 8 comprising: (a) adding a dual functional compound with an acidic aluminum salt to form an aqueous solution, wherein the dual functional compound comprises an anchoring group that attaches the dual-functional compound to the pigment surface, and a basic amine group comprising a primary, secondary or tertiary amine; (b) adding a base to the mixture from step (a) whereby the pH is raised to about 4 to about 9 to form a turbid solution; and (c) adding the mixture from step (b) to a slurry of inorganic particles whereby a hydrous alumina and the dual functional compound are deposited on the pigment surface. The self-dispersing pigments prepared by this process are useful in making décor paper that may be used in paper laminates.

  • Patent number: 9267039
    Abstract: A cost-effective process for loading particulate pigment into a polymer concentrate includes adding a basic pH aqueous solution having a water soluble organic salt to a milled particulate pigment to form an organic-coated particulate pigment. The pH of the basic aqueous solution is sufficiently basic that the water soluble organic salt remains in a salt form. Without a prior micronization step, the organic-coated particulate pigment is mixed with a polymer resin to form a polymer concentrate having from about 50% to about 87% by weight particulate pigment with dispersibility comparable to micronized organic-coated particulate pigment.

    Abstract: Disclosed are a functional reinforcing filler including inorganic particles surface-modified with an alkenylsilanol obtained by hydrolyzing an alkenylalkoxysilane compound, and a method for preparing the same. Since the disclosed functional reinforcing filler has a functional group having a double bond, it has good reactivity for styrene-butadiene rubber and sulfur. Thus, when used as a functional reinforcing filler in the manufacture of rubber, it allows improvement of physical properties through adjustment of the addition amount of sulfur without additional use of the coupling agent. In addition, because of superior hydrolysis reactivity, the problem of alcohol can be solved and a rubber mixture with long scorch time can be prepared. In particular, when the functional reinforcing filler of the present invention is used in the manufacture of tires, improvement in modulus, tensile strength, rotational resistance and wet traction performance can be expected.

  • Publication number: 20120270028
    Abstract: The invetion relates to a titanium dioxide-based photocatalyst containing carbon that is highly photoactive in visible light (vlp-TiO2) and to a method of manufacture. The vlp-TiO2is manufactured by mixing a fine grained titanium compount (BET?50 m2/g) with an organic carbon compound and subsequent thermal treatment at temperatures up to 350° C. The carbon content amounts to 0.05 to 4% by weight, preferably 0.4 to 0.8% by weight. The product is characterized by an ESR spectrum which displays only one significant signal in the g value range from 1.97 to 2.05 at g about 2.003. The inventive photocatalyst can be used for to degrade contaminants and pollutants in liquids and gases.

  • Publication number: 20120270977
    Abstract: A titanium dioxide dispersion liquid in which the transmittance is 80% or more is manufactured by dispersing titanium dioxide fine particles having an average primary particle diameter of 1 nm or more and 30 nm or lower in a solution containing diglyme which is a solvent and trimethoxypropylsilane which is a dispersant. By doping titanium dioxide fine particles with nitrogen atoms, and then dispersing the same by an atomization device using beads having an average particle diameter of 15 ?m or more and 30 ?m or lower, a titanium dioxide dispersion liquid capable of maintaining transparency stability over a long period of time is manufactured.

  • Patent number: 8242206
    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%.

  • Publication number: 20120199727
    Abstract: A titanium black dispersion includes titanium black particles, a dispersant, and an organic solvent. When the titanium black dispersion is for a wafer level lens, 90% or more of dispersed objects that consist of the titanium black particles have particle diameters of 30 nm or less, or dispersed objects including the titanium black particles contains Si atoms and the content ratio of Si atoms to Ti atoms (Si/Ti) in the dispersed objects is 0.05 or higher. When the titanium black dispersion is used for formation of a light-shielding film that is provided on one side of a silicon substrate having an image pickup device section on the other side, and that shields against infrared light, 90% or more of dispersed objects that consist of the titanium black particles have particle diameters of 30 nm or less.
