  • Patent number: 10538664
    Abstract: Provided are aqueous resin solutions having unique rheologies and products incorporating the same. The water-based materials provided herein are thermo-thickening, and the materials increase dramatically in viscosity (at least 100 times) in a desired temperature range increase (20 C to <100 C) at ambient pressure. Suitable resins comprising a hydrophobic group and a hydrophilic group may be selected from an epoxy resin, a phenol-formaldehyde resin, a polyurethane resin, an acrylic resin, a polyester resin, an acrylic-urethane resin, a melamine resin, a melamine-formaldehyde resin, an amino resin, and combinations thereof. A specific epoxy functional resin/polymer suitable for the resin solutions are prepared by reacting (A) an epoxy pre-polymer of (1) one or more polyols and (2) one or more epoxy functional materials with (B) a di- or polyamine, thereby forming the aqueous thermo-thickening resin solution. The resin solutions are substantially free of cross-linking agents.

  • Patent number: 8686095
    Abstract: An epoxy resin with amine functionality is manufactured continuously through a first reaction zone in which an epoxide-functional resin is made by ring-opening addition, a second reaction zone in which the resin is reacted with amine to make an epoxide-functional product, and a third reaction zone in which the epoxide functional product is reacted with amine to make the epoxy resin with amine functionality. In other embodiments, some amine may be added in the first reaction zone to produce an epoxide functional product, with elimination of the second reaction zone, or all of the amine reactant may be added in the first reaction zone to produce an amine functional product, with elimination of both the second and third reaction zones. Optionally, solvent may be removed in an evaporation zone and recycled into the continuous process and further zones may be included to incorporate crosslinker, additives, and to emulsify the resin.

  • Patent number: 7842177
    Abstract: A pigmented granular pigmented coating feedstock is prepared by melting a resin, which can be a solid resin based on polymerizable ethylenically unsaturated monomer or epoxy based resin, and a solid or viscous curing agent, blending the molten mass, and cooling to form a solid. The solid blend of resin and curing agent is ground to produce a granular feedstock. The feedstock is readily storable or shippable to a location for coating preparation. Alternatively a solid coating can be ground after shipping. An aqueous coating is made by dispersing the feedstock in water and mixing to form a dispersion. A salting agent and at least one additive can be added to form an aqueous coating composition. An article can be coated with the dispersion, for example, by electrodeposition.
