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.
A method for preparing an aqueous based coating system for coating onto paper and/or paperboard for providing barrier to liquid, moisture vapor, oil and grease, comprising:
An aqueous based coating system for coating onto paper and/or paperboard for providing barrier to liquid, moisture vapor, oil and grease, comprising a polymer emulsion system or natural-based binding system and a pigment system, wherein the pigment system comprises a surface treated pigment.
A coating system for coating onto a paper and/or paperboard comprising a pigment and a polymer emulsion or natural-based binding system that has been hydrophobized by the addition of materials selected from the group consisting of silanes, siloxanes, siloxane/silicone resin blends, and their carbon-based analogs.
A method for preparing an aqueous based coating system for coating onto paper and/or paperboard for providing a barrier to liquid, moisture vapor, oil and grease, comprising:
