Provided is a kaolin having a finer particle size and a narrower particle size distribution, in combination with suitable morphology. Also provided are a method of preparing the kaolin product and methods of use.

Pigment for paper and coatings

Disclosed herein are, for instance, coated substrates comprising cellulose-based substrates with surface-treated aqueous-based polymer coatings. In some embodiments, the aqueous-based polymer coatings are surface-treated using corona treatment. Methods of making and using the same are also disclosed.

Coated substrate comprising a surface-treated, aqueous-based polymer coating and methods of making and using the same

A method for preparing an aqueous based coating system, and coating systems made thereby, for coating onto paper and/or paperboard for providing barrier to liquid, moisture vapor, oil and grease including a pigment and a polymer emulsion system or natural based binding system. One alternative of the method includes surface treating a pigment to form a pigment system and mixing a polymer emulsion system or natural based binding system with the pigment system. Another alternative of the method includes mixing a pigment and polymer emulsion system or natural based binding system and hydrophobizing the polymer emulsion system or natural based binding system by adding silanes, siloxanes, siloxane/silicone resin blends, or their carbon based analogs.

Enhanced performance of mineral based aqueous barrier coatings

The present application relates to reaction mixtures comprising biomass, a solid acid catalyst and cellulolytic enzymes or organisms expressing such enzymes for converting biomass to useful feedstocks and methods of forming products via fermentation using the said reaction mixture.

Converting biomass to fermentative products

This invention is directed to a method of stabilizing high solid slurries, like kaolin slurries, the method comprises causticizing the sodium polycrylate or polyacrylic acid used in a dispersant blend to a pH of above 9. The method comprises a homogeneous dispersant blend of sodium carbonate, sodium polyacrylate, sodium silicate, and sodium hydroxide. This invention is also directed to a method of stabilizing high solid slurries, like kaolin slurries, by adding sodium polyacrylate at an acidic pH range or polyacrylic acid solution to the slurries: and adding a blend of soda ash and sodium silicate to the slurries.

Methods for stabilizing hydrous kaolin

This invention is directed to a paper coating or binding formulation, comprising an aqueous emulsion which comprises a copolymer derived from one or more monomers, and an ultra fine kaolin pigment. In certain embodiments, this invention is directed to a blend of high T9 latex (substantially non-film forming) and ultrafine kaolin. This invention is also directed to a paper comprising a fiber matrix and a coating or binding composition comprising an aqueous emulsion which comprises a copolymer deviced from one or more monomers, and an ultrafine kaolin pigment.

Glossing system for paper and paperboard coating

Disclosed are methods of processing kaolin to produce ultrafine hydrous kaolin. The methods involve processing gray crude kaolin by subjecting the kaolin crude to flotation and then centrifuging the kaolin to provide a fine stream that is subject to refinement. Also disclosed are systems for the automated processing of gray crude kaolin to produce the ultrafine hydrous kaolin and paint compositions that contain the ultrafine hydrous kaolin.

Ultrafine hydrous kaolin pigments, methods of making the pigments, and methods of using the pigments in gloss paint formulations

The disclosed invention relates to a blended hydrous kaolin clay product comprising a platy coarse kaolin clay and a fine, hydrous kaolin clay. The blended kaolin clay product is suitable for use as a raw material component in the formation of cordierite products.

Blended hydrous kaolin clay product

The present invention provides a thermal paper composite precursor comprising (a) a substrate layer; and (b) a base layer positioned on the substrate layer, the base layer comprising a binder and at least one porosity improver wherein the thermal paper composite precursor has a thermal effusivity that is at least about 2% less than the thermal effusivity of porosity improver-less thermal paper composite precursor. The thermal paper composite precursor is useful in making thermal paper composite.

Thermal paper

Disclosed are methods of processing kaolin to produce two distinct grades of kaolin in a simultaneous manner. The methods involve processing kaolin by degritting a kaolin crude; subjecting the degritted kaolin crude to flotation to provide a kaolin having reduced titania content; ozonating the kaolin having reduced titania content; centrifuging the kaolin to provide a coarse stream and fine stream; refining the coarse stream into a coarse engineered kaolin pigment; and refining the fine stream into a fine glossing kaolin pigment. Also disclosed are systems for the automated processing of kaolin to produce two distinct grades of kaolin with real time feedback.

Kaolin pigments and methods of making the same

In a process for preparing a white pigment mixture suitable for coating paper wherein a cationically bulked kaolin clay pigment is dispersed in water in the presence of an anionic dispersant and mixed with a calcium carbonate pigment, the improvement which comprises using an epichlorohydrin amine complex to bulk said kaolin, and employing as the dispersant the combination of at least 0.2% based on the dry weight of said cationically bulked kaolin of a condensed naphthalene sulfonate complex having a molecular weight of 2000 to 10,000 and a sodium polyacrylate salt having a molecular weight of 2000 to 5000, said dispersant being free from lignosulfonate.

Chemically bulked kaolin clay pigment compatible with calcium carbonate and manufacture thereof

An improved method for purifying titania contaminated kaolin clay by froth flotation which features the use an hydroxamate flotation collector at a neutral or mildly alkaline pH wherein a slurry of the impure clay is conditioned for the flotation step in a baffled conditioning apparatus provided with mean for imparting sufficient mechanical energy to heat a dispersed slurry of the impure clay before flotation.
