    Abstract: The present invention is the formation of solid polymer layers under vacuum. More specifically, the present invention is the use of “standard” polymer layer-making equipment that is generally used in an atmospheric environment in a vacuum, and degassing the liquid material prior to injection into the vacuum. Additional layers of polymer or non-polymer may be vacuum deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteristics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for curing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced material wetting angle that facilitates spreading of the material and provides a smoother finished surface.

    Abstract: A heat-resistant resin film having a metallic thin film accumulated thereon or an endless belt having a metallic thin film accumulated thereon having good mechanical characteristics is produced in a simple process. A metallic thin film is formed on an inner surface of a cylindrical substrate, and a layer of a heat-resistant resin is formed thereon. An accumulated body of the heat-resistant resin and the metallic thin film is peeled off from the substrate. The metallic thin film may be formed by electroplating, electroless plating or vapor deposition, or may also be formed by attaching a metallic foil having been prepared on an inner surface of the substrate. The heat-resistant resin layer is formed by injecting a polyamide acid solution in a rotational drum, and then formed by centrifugal forming by rotating the rotational drum on rollers under heating. After forming, imidization is conducted by heating and baking to form a film member of a thermosetting polyimide.

  • Patent number: 6340519
    Abstract: A water-based chipping-resistant paint which comprises 30 to 65 weight percent of solid matter and 0.1 to 10 weight percent of low-temperature volatility solvent as a water-based dispersion substance and wherein the solid matter contains 15 to 75 weight percent of film-formable resin, 0.2 to 25 weight percent of thermoexpandable microspheres, and 20 to 80 weight percent of chipping-resistant material, facilitates vaporization of water at the time of film formation owing to mixing of the low-temperature volatility solvent, can prevent cracking and blistering of a film due to water remaining in the film and vaporization of water remaining after the film formation, and readily form a thick film owing to an expansion effect of the thermoexpandable microspheres at the stage of baking after coating, and therefore is suitable for a chipping resistant underbody coating for automobiles.

  • Patent number: 6338876
    Abstract: This invention relates to a process for hydrophilic treatment of an aluminum material comprising a step for priming in which a primer containing the nitrate or related compound of a metal selected from aluminum, zirconium, cerium, chromium, and iron is applied to the surface of an aluminum material so that the amount of adhering metal becomes 1.0 mM/m2 or more and then the primer is baked at the specified temperature and a step for coating in which a hydrophilic coating is applied to the primer film formed in said step for priming and then baked at the specified temperature. This invention also relates to primers and hydrophilic coatings useful for the aforementioned treatments. It is possible to form a hydrophilic film, with pronounced hyrdophilicity particularly after press forming, on the surface of an aluminum material.

  • Publication number: 20020004102
    Abstract: A simple surface treatment process is provided which offers a high performance surface for a variety of applications at low cost. This novel surface treatment, which is particularly useful for Ti-6A1-4V alloys, is achieved by forming oxides on the surface with a two-step chemical process and without mechanical abrasion. First, after solvent degreasing, sulfuric acid is used to generate a fresh titanium surface. Next, an alkaline perborate solution is used to form an oxide on the surface. This acid-followed-by-base treatment is cost effective and relatively safe to use in commercial applications. In addition, it is chromium-free, and has been successfully used with a sol-gel coating to afford a strong adhesive bond that exhibits excellent durability after the bonded specimens have been subjected to a harsh 72 hour water boil immersion. Phenylethynyl containing adhesives were used to evaluate this surface treatment with a novel coupling agent containing both trialkoxysilane and phenylethynyl groups.

  • Patent number: 6337119
    Abstract: Master discs and similar devices used in the production of digital data storage and recording discs and the like are produced with a substrate member which is provided with a layer of material which is applied to the substrate member in liquid form of a thickness greater than the surface roughness of the substrate member and of a thickness greater than any particulates present on the substrate member. The material layer is preferably a polymer such as epoxy, acrylic or styrene and is hardenable by exposure to UV light, heat, air circulation or catalytic reaction to provide a substantially smooth flat surface for receiving a data bearing film. The film may be treated to generate bumps or pits representing digital signals, for example, which are free of any defects resulting from surface roughness or contamination of the substrate member.
