Patent number: 8796364
Abstract: The present invention relates to a method of obtaining an additive for coatings that contains nanoparticles of one or more compounds, preferably metallic, selected in relation to the property that is desired to be transferred to the coating, which comprises a first pretreatment phase in which the water content of the active agent is reduced, replacing it with a vehicle compatible with the coating, and a second phase in which it is mixed with a resin compatible with the coating, a dispersant and a solvent, which are also compatible with it. The additive produced by this method contains nanoparticles of one or more compounds, preferably metallic, which become dispersed homogeneously in the coating once incorporated therein.

Patent number: 8791186
Abstract: A method of determining that a thermoplastic was insufficiently dried before forming into a molded plastic part. The method comprises preparing a mixture of a thermoplastic polymer and an off-gassing compound, wherein the off-gassing compound is selected to release all water of hydration in response to target drying conditions specified for the thermoplastic polymer. The mixture is dried at actual drying conditions, and then heated to reduce the viscosity of the thermoplastic polymer and allow the mixture to flow. The mixture is then made to flow into a mold to form a plastic part at a molding temperature, wherein the molding temperature will cause any remaining water of hydration in the off-gas sing compound to off-gas and form surface irregularities in the plastic part. Non-limiting examples of the off-gassing compound include hydrated metal halides and ionic hydrates.

Patent number: 8759430
Abstract: A novel olefin or polyester (PET) fiber or yarn, or a textile fabric, tufted, knitted, woven and non-woven, is manufactured using olefin or polyester (PET) yarns that contain variable amounts of a unique dye acceptor additive. The fabrics and yarns using this invention can be processed using existing nylon dyeing and finishing systems at atmospheric pressure. The dye acceptor additive can be easily and inexpensively dosed into a conventional yarn or fiber extruder or can be incorporated in blended pellets which can be extruded into a nylon dyeable polyester (PET) or olefin fiber or yarn. A fabric with more than one tone of a color can be dyed in a single dye bath by using different amounts of additive in different yarns. This invention is of particular value in the apparel, carpet and home furnishings industries.
