Abstract: 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.

Abstract: 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.

Abstract: This invention is directed to novel pigments, pigment systems (including components not classified as pigments) and formulations for use in an aqueous coating system applied onto cellulosic (paper and/or paperboard) and non-cellulosic substrates (polyethylene (PE), polylactic acid (PLA), polyvinyl acetate (PVAc), etc.) to impart barrier properties.

Abstract: A heated mixture comprising dehydroxylated kaolin and a high refractive index pigment is disclosed. When the dehydroxylated kaolin is metakaolin, the heated mixture has a GE brightness greater than 86% and a Hunter yellowness index of less than about 11. When the dehydroxylated kaolin is fully calcined kaolin, the heated mixture has a GE brightness greater than 89%. The heated mixture is advantageously used in decorative paper. Also disclosed are methods of using and making the decorative paper, and decorative laminates containing the decorative paper.
