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

FCC catalysts having improved attrition resistance are provided by mixing a cationic polyelectrolyte with either zeolite crystals or a zeolite-forming nutrient and/or a matrix material, prior to or during formation of a catalyst microsphere.

Method of producing FCC catalysts with reduced attrition rates

A catalyst particle which comprises a metallic oxide such as kaolin is provided with the unique structure by mixing small amounts of a polyphosphate structuring agent with the metallic oxide and heating the mixture of metallic oxide and polyphosphate to allow reaction of the structuring agent with the metallic oxide.

Thermochemical structuring of matrix components for FCC catalysts

A fully calcined kaolin pigment extender is provided which has a product Mullite Index (M.I.) of 25.0 or higher. The calcined kaolin pigment extender can be advantageously used in paints to improve scrub and burnish resistance.

Generation kaolin based paint pigment extender

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

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

A metal trap particle used for passivation of metals during FCC cracking comprises a calcined spray dried particle formed from kaolin, magnesium oxide or magnesium hydroxide and calcium carbonate. The metal trap particle contains at least 10 wt. % magnesium oxide which improves metals passivation during FCC cracking.

Heavy metals trapping co-catalyst for FCC processes

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.
