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

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

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

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.
