  • Patent number: 11634358
    Abstract: A curable glass coating composition including 5-70 wt % aliphatic polycarbonate diol, 5-60 wt % crosslinker, 1-20 wt % extender, 4-20 wt % fatty alcohol, and 2-30 wt % crystalline or amorphous powder filler material, and optionally 2-20 wt % aliphatic polyester polyol and 2-20 wt % cycloaliphatic epoxy. The coating composition can be applied to a glass substrate and cured to form a decorative cured polyurethane coating layer on the substrate that has improved caustic and UV resistance.
    Type: Grant
    Filed: January 3, 2018
    Date of Patent: April 25, 2023
    Assignee: Ferro Corporation

  • Patent number: 9656911
    Abstract: Various agents for improving adhesion of cold end coatings on glass surfaces are described Also described are agents for improving bonding between cold end coatings and organic inks. And, methods and related detection solutions for detecting the presence of cold end coatings on a substrate such as a glass bottle are disclosed. Additionally, particular additives and primers are described that can be applied onto cold end coatings for improving adhesion thereto.

  • Patent number: 9150750
    Abstract: An acrylate-based curable printing medium is disclosed. Acrylates, in the form of monomers, dimers, trimers and oligomers, as well as resins, form an interpenetrating polymer network by crosslinking, which is effected by heat, and optionally peroxide curing agents. Formulations can be tailored to achieve desired properties of the cured polymer including film hardness, burnout properties, and adhesion to glass. Such properties are adjusted by manipulating the relative proportions of the acrylic monomers, oligomers and resins that are used as a ceramic medium or vehicle.

  • Patent number: 8889778
    Abstract: A low VOC medium is described. The medium comprises a low VOC solvent such as propylene carbonate, dimethyl carbonate, or combinations thereof. The low VOC medium also comprises one or more glycol ethers. In addition, the low VOC medium also includes one or more surfactants and/or dispersants. The low VOC medium may also optionally comprise one or more binders. The low VOC medium can be used in preparing coating compositions and pastes that are intended for use in applications that include a firing step.
