  • Patent number: 6264747
    Abstract: Several techniques may be used for forming a colored interference filter coating on a substrate such as polyester film. The interference filter has two metal reflective films, at least one of which is semi-transparent. A layer of transparent acrylate polymer dielectric between the metal layers completes the interference filter, which may be sandwiched between protective layers. The dielectric is formed by evaporating an acrylate monomer having a molecular weight in the range of from 150 to 600. Preferably the acrylate monomer has a molecular weight to acrylate group ratio in the range of from 150 to 400. The acrylate condenses on the substrate and is polymerized in situ for forming a monolithic film with a sufficient thickness to produce an interference color. In several embodiments different areas of the film have different thicknesses for producing different interference colors.

  • Publication number: 20010001284
    Abstract: A thermoplastic container or packaging material is given low oxygen permeability by coating with a crosslinked acrylate layer and a layer of oxygen barrier material deposited over the acrylate layer. Another acrylate layer may be deposited over the oxygen barrier. The oxygen barrier is selected from the group consisting of silicon oxide, aluminum oxide and metal. The acrylate layer may be formed from a photopolymerizable polyfunctional acrylate that is sufficiently low viscosity to be sprayed on the substrate or applied by dipping. Alternatively, the acrylate layer is a polymerization product of an acrylate monomer which is evaporated in a vacuum, condensed on the substrate and polymerized by irradiation by ultraviolet or an electron beam.

  • Patent number: 6218004
    Abstract: Sheet materials according to the present invention comprise a sheet material substrate, such as for example a film or paper sheet, with a polymer base coating overlying and adhered to a surface of the sheet material substrate. The base coating comprises a radiation cured crosslinked polymer derived from at least one vapor deposited acrylate prepolymer composition having a molecular weight in the range of from about 150 to 600. A metal layer is deposited on and overlies a surface of the base coating, and a polymer top coating overlies and is adhered to a surface of the metal layer. The top coating comprises a radiation cured crosslinked polymer derived from a vapor deposited acrylate prepolymer composition having a molecular weight in the range of from about 150 to 600 and a ratio of its molecular weight to its number of acrylate groups (MW/Ac) in the range of from about 150 to 600.

  • Patent number: 5945174
    Abstract: Sheet materials according to the present invention comprise a sheet material substrate, such as for example a film or paper sheet, with a polymer release coating overlying and adhered to a surface of the sheet material substrate. Single and multilayer release coatings can be formed on the substrate by vapor deposition of silicone acrylates and/or fluorinated acrylates. These coatings can be applied in thickness of 0.05 micron to 1.0 micron to achieve a range of release properties. These coatings can be applied in a very thin single layer on relatively smooth substrates or in a multilayer form on rough substrates such as paper. The new coating process described here has lower process and materials costs, improved adhesion, low slip, and excellent release characteristics.

  • Patent number: 5440446
    Abstract: Material for winding high voltage capacitors is prepared by evaporating polyfunctional acrylate monomer having a molecular rate in the range of from 150 to 600 and condensing the acrylate as a monomer film on a dielectric substrate. The acrylate is polymerized by irradiation by ultraviolet or electrons. Sometimes both faces of the dielectric are coated to protect the thermoplastic dielectric from swelling when exposed to dielectric liquid. The metallized layer provides an electrode of the capacitor. A polymerized acrylate layer may be applied over the metal layer. Electrical contact can be made to the metal layer by Schooping even though the metallized layer is covered by a layer of acrylate. Low oxygen permeability polypropylene, polyester or nylon sheet has a layer of crosslinked acrylate and an oxygen barrier layer formed of silicon oxide, aluminum oxide or metal. Adhesion is enhanced by plasma or corona treatment of a surface immediately before deposition.

  • Patent number: 5123523
    Abstract: The present invention provides an endless conveyor belt for conveying articles within a high temperature environment, such as a sputtering apparatus. A sputtering apparatus employs endless conveyor belts mounted on power operated pulleys to convey articles within the high temperature environment of such an apparatus. The conveyor belt comprises an elongated, spring-like member having two opposed ends. The spring-like member is prevented from stretching by either a tubular wire braid within which the spring-like member is received in a close fitted engagement or, one of more cables located within the spring-like member. In case of the tubular wire braid covered spring-like member, the ends are joined by wire end loops connected to the opposed ends of the spring-like member which are in turn connected by a link.

  • Patent number: 4740863
    Abstract: A small multilayer capacitor, such as an MLC capacitor, has in one of its end terminations a passivation layer surrounded by nested sputter-coated metallization films to provide a safeguarding feature so that the capacitor will not fail short. A process for providing the terminations at the ends of chips for such small MLC capacitors includes applying at least three nested thin films of metallization at the opposite ends of each chip and over the surface of the chip between the ends, and forming the passivation layer before applying the outer nested films, and finally removing a portion of thin films of metallization material intermediate the ends, to provide an MLC capacitor having proper metallized end terminations. Preferably, the thin films are applied to cover the entire surface of each chip by sputtering thin film material onto a batch of tumbling chips.
