  • Curable acrylate based printing medium
    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.
