    Assignee: Sun Chemical Corporation
    Inventors: Alexander Lahr, Bruce Marshall
  • Patent number: 12351719
    Abstract: Method for recycling printed plastic articles without contaminating or staining the recycled plastic with color due the printed ink. The ink is a water-based composition comprising select self-crosslinking acrylate copolymers or polyurethane resins, which inks exhibit good adhesion under conditions of use, but which are readily removed as solid particles when exposed to a hot caustic solution. Due to the inks being removed as solid particles, and not dissolving into the ink, the recycled plastic remains uncontaminated by the ink during recycling.
    Type: Grant

  • Publication number: 20240417569
    Abstract: The present invention provides water-based primer compositions comprising polyolefin type adhesion promoters. Preferably, the polyolefin type adhesion promoter is a maleated polyolefin type adhesion promoter. The primer compositions improve adhesion of water-based inks and coatings to low-treatment substrates.

  • Publication number: 20240294786
    Abstract: The present invention provides a printing ink or coating composition comprising a self-crosslinking acrylic polymer and a silicone emulsion wherein the self-crosslinking acrylic polymer has a minimum film forming temperature of less than 25° C. Furthermore, the present invention also provides a process for preparing a coated substrate, in particular a polyboard substrate, and an article made from the coated substrate, such as a milk or juice carton.

  • Patent number: 11753556
    Abstract: Described herein are opaque water-based inks that include water and an opacity-providing polymer component. In one aspect, the opacity providing polymer component is a hollow sphere polymer material. The opacity-providing polymer material may replace all or part of white opacifying pigment material, such as titanium dioxide. Also described herein is a method of opacifying a printing ink by adding hollow sphere resin particles and a colorant to a printing ink that comprises water as a volatile component.

  • Patent number: 10655026
    Abstract: The present invention is directed to a water-based printing ink or coating composition comprising an acrylic resin emulsion and an epoxy ester resin dispersion. The present invention also provides a process for preparing the printing ink or coating composition comprising forming an emulsion of an acrylic resin having the general formula I by copolymerizing monomers in water, forming an epoxy ester resin dispersion by adding the epoxy ester resin to a solvent and combining the acrylic resin emulsion and the epoxy resin ester dispersion to provide the composition. Finally the present invention provides a process for preparing an article with a coating or an ink printed thereon which comprises applying the ink or coating composition to a surface of an article and drying the composition. The compositions exhibit a high degree of alkali resistance, acid resistance and/or water softener resistance.

  • Patent number: 8001784
    Abstract: A system that utilizes the naturally superheated fluids available from hydrothermal vents to harness the almost limitless quantities of heat energy they contain. It consists of one major system that has three parts: (i) funnel, (ii) pipes, and (iii) any combination of several mechanical attachments. The recovered heat energy will then be used to drive steam turbines or other equipment for electricity generation, water desalination, or any other thermal energy use. It could also be simultaneously or separately fed into resource recovery equipment for the recovery of valuable metals, minerals, and chemicals without system modification.
