  • Patent number: 10773506
    Abstract: A process for applying a release agent and pressure sensitive adhesive to cut sheet media to thereby eliminate a separate release liner. A silicone oil plus additive release layer is applied during fusing on a top surface of cut media and then UV cured. A pressure sensitive adhesive layer is applied next. The cut sheets are then stacked and a compressive force is applied that transfers the pressure sensitive adhesive from one sheet to another and helps hold the stack together.

  • Publication number: 20190322098
    Abstract: An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

  • Patent number: 10052874
    Abstract: A method for forming an ink jet printhead comprises processing an epoxy adhesive such that negative effects from physical contact with particular inks are reduced or eliminated. Conventional adhesives processed using conventional techniques are known to gain weight and squeeze out when exposed to certain inks such as ultraviolet inks, solid inks, and aqueous inks. An embodiment of the present teachings can include processing of a particular adhesive such that the resulting epoxy adhesive is suitable for printhead applications.
