  • Publication number: 20190240977
    Abstract: The present teachings describe a printhead assembly. The printhead assembly includes a first plate and a second plate stacked together. The printhead assembly includes a first adhesive between the first plate and the second plate for bonding the plates together. The printhead assembly includes a second adhesive surrounding an outer edge of the first adhesive wherein the second adhesive has an oxygen migration rate lower than an oxygen migration rate of the first adhesive. An oxygen sensitive component is contained within the outer edge of the first adhesive.

  • 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.

  • Patent number: 9958797
    Abstract: A toner process comprising (a) providing at least one amphiphilic block copolymer prepared by surfactant-free emulsion polymerization comprising: dissolving a hydrophilic monomer in water; adding a hydrophobic monomer; adding a feed initiator to produce a colloidal dispersion of amphiphilic block copolymer; and optionally, discharging the amphiphilic block copolymer; (b) contacting one or more of a latex polymer, a wax; and a colorant with the colloidal dispersion of amphiphilic block copolymer to form a blend; or contacting the discharged amphiphilic block copolymer with one or more of a latex polymer, a wax dispersion, and a colorant dispersion, and forming a further dispersion; (c) heating the blend or further dispersion at a temperature below the glass transition temperature of the latex polymer to form aggregated toner particles; (d) adding a coalescing agent to the toner particles thereby coalescing the toner particles; and (e) recovering the toner particles.

  • Patent number: 9828251
    Abstract: Silica aerogels with improved properties are disclosed together with methods for synthesizing such aerogels. The improved properties include lower thermal conductivity (better insulating capacity), lower acoustic velocity, lower dielectric constant and improved ductility. Greater tunability of the refractive index can also be achieved. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation or aerogel structures. Generally speaking, the improvements arise from control of the synthesis to create a morphology of primary clusters and diverse-sized secondary clusters of dense silica aerogels separated by less densely packed regions. By providing a broader range of secondary clusters and/or pore sizes and loose connectivity between clusters, reductions can be achieved in thermal conductivity and flexural modulus.
