    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.

  • Patent number: 8470727
    Abstract: Zinc carboxylate clays and zinc carboxylate organoclays, methods for their preparation, and compositions containing the same are disclosed. The methods comprise either mixing a zinc clay composition with a carboxylic acid, or mixing a carboxylic acid with a zinc ammonia complex solution, then combining the resulting zinc carboxylate salt with a slurry or suspension of a cation-exchangeable clay, to prepare the zinc carboxylate clay. These clays can be further intercalated with quaternary ammonium salts to make zinc carboxylate organoclays. The present clays may be used in compositions and/or as additives in rubber and plastic formulations and products and in catalyst formulations.

  • Patent number: 8470921
    Abstract: This invention is an acoustic device protected by an acoustically transparent low water permeability encapsulant made from an acoustically clear polymer such as polyurethane. High aspect ratio clay nanoparticles are positioned in the substrate in overlapping layers with layers of the substrate interposed. The invention also provides a method for forming an acoustically transparent low permeability encapsulant about an acoustic device. The method includes treating high aspect ration clay nanoparticles to make them organophilic. The treated nanoparticles are then mixed in a polymer resin in such a way as to form an intercalated mixture. A curing agent is added to the mixture, and the mixture is allowed to set. When set the resulting intercalated mixture produces an acoustically clear, low permeability polymer coating.

  • Patent number: 8404084
    Abstract: A filler treatment process enhances the fixation of anionic latex on filler in a short time. Anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. The anionic latexes applied by this process are totally and irreversibly fixed or bound onto the filler particles and the treated filler particle agglomerate to form an aggregated filler slurry which is stable over time. The latex-treated filler slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance.
