  • Patent number: 6850681
    Abstract: A buffer coating for optical fibers is disclosed which includes a halogenated epoxy resin for flame-retardancy, and elastomer modified epoxy resin for tensile strength and flexibility, a low viscosity bisphenol resin for structural integrity, a viscosity modifier for improved process or extrusion properties, a polyol to increase the cure rate and cross-linking during curing, a slip agent or surfactant to reduce the adhesion of the buffer layer to the cladding and to further improve the flow characteristics during extrusion, and a photo-initiator. The buffer layer is flame-retardant and has a fast UV cure rate.

  • Publication number: 20030205317
    Abstract: A method for assembling a flat panel display is disclosed whereby the conductive layers disposed on the inside surfaces of the two panels to be laminated are connected or laminated together with a pressure-sensitive adhesive or a latent-cure adhesive. Protective insulating layers on the conductive layers disposed on the inside surfaces of the panels have been eliminated. The adhesive connecting the opposing conductive layers serves as a suitable insulating layer. An improved flat panel display whereby the conductive layers on opposing panels is connected with either a latent-cure adhesive or a pressure-sensitive adhesive is also disclosed. Methods of laminating panels of EL displays and methods of laminating substrates of optoelectronic devices are also disclosed.

  • Patent number: 6617371
    Abstract: A single component liquid heat-curable adhesive formulation that is stable at room temperature. The formulation includes from about 5 to about 70 wt % of at least one acrylate monomer, from about 5 to about 94 wt % of an acrylate oligomer, and from about 0.1 to about 10 wt % of a thermal initiator selected from the group consisting of diacyl peroxides, benzoyl peroxides and peroxy esters. A photo initiator may be included thereby rendering the stable liquid formulation to be both heat-curable and UV-curable.

  • Patent number: 6472451
    Abstract: A UV-curable acrylate base adhesive composition for digital versatile discs and other substrates, a method for bonding verstile digital disc layers together with a UV-curable adhesive, and a digital versatile disc bonded by a UV-curable or a radiation curable adhesive. The adhesive comprises acrylate functional components, non-acrylate reactive diluents (e.g. having acrylamide, or N-vinyl functionality) and thiol compounds.
