Abstract: Electrically resistive material including platinum and from about 5 and about 70 molar percent of iridium, ruthenium or mixtures thereof, calculated based on platinum as 100%, are disclosed.

Abstract: Liquid organic material is controllably delivered to a receptacle located in the center of a heated surface capable of horizontally rotating about its central axis. As the heated surface rotates, material deposited within the central receptacle is forced outwardly and across the rotating surface. As the material moves radially, it evaporates into a vapor which is then transported to one or more nozzles. From the nozzles, the vapor is applied to a substrate and condensed. Relative to existing devices and methods, the present invention enables the evaporation of a wider variety of organic liquids, greater reliability in continuous operation, a decrease in maintenance, and a larger and more constant material flow rate.

Abstract: A method and apparatus for coating a surface of a substrate using combustion chemical vapor deposition is disclosed. A chemical vapor deposition stream, composed of a coating precursor and a combustible medium, is directed toward a substrate and combusted to provide a reacted coating precursor in a gaseous plume. The plume is modified by exposing it to a shield prior to the plume contacting the surface of the substrate and depositing a coating thereon. The shield serves to control the coating thickness and material characteristics of the deposited material.

Abstract: Material with high oxygen barrier properties is prepared by evaporating polyfunctional acrylate monomer and condensing the acrylate as a monomer film on a plastic sheet, or by roll coating acrylate monomer onto a sheet in a vacuum. The acrylate is polymerized by irradiation by ultraviolet or electron beam. A layer of metal or oxide oxygen barrier material is applied over the first layer of cross-linked acrylate. A polymerized acrylate layer is applied over the metal layer. Low oxygen permeability polypropylene, polyester or nylon sheets can be made by these methods. Adhesion of the acrylate layer on the plastic sheet substrate is enhanced by reactive plasma treatment of a surface immediately before deposition, the plasma treatment and coating being conducted in vacuum within less than three seconds between plasma treatment and coating. Condensation efficiency is also enhanced by chilling the substrate of the substrate on which the acrylate is condensed to temperatures below 0° C.

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.

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.

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.
