  • Patent number: 6231939
    Abstract: A thermoplastic container or packaging material is given low oxygen permeability by coating with a cross-linked 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: 6106951
    Abstract: The invention provides a process that includes a first step of reacting the hydroxyl groups of a acrylic resin having hydroxyl groups and carbamate groups with a compound that converts the hydroxyl groups to new groups unreactive with an aminoplast crosslinker; a second step of combining the acrylic resin reaction product with at least an aminoplast crosslinker to form a coating composition; and a third step of applying the coating composition to a substrate and curing the applied coating layer, in which substantially no ether linkages are formed. Aminoplast crosslinkers are desirable for other reasons such as providing high solids coatings having excellent appearance that cure under moderate conditions. Avoiding the ether linkages that could be formed by reaction of aminoplast crosslinkers with hydroxyl groups improves the resistance of the cured coating to environmental etch.

  • Patent number: 5900320
    Abstract: The present invention aims to improve soundproof and heat insulating properties of a foamed plastic by reducing internal cells pressure inside foamed resins. A base polymer such as a polyester-based polyol and a volatile foaming agent having an conjugate unsaturated group (i.e., conjugate double carbon bonds and/or triple carbon bonds) such as chloroprene (bp. 51.degree. C.) and calcium stearate were blended and then mixed with a hardening agent such as hexamethylene diisocyanate. The volatile foaming agent existing in open cells of the foamed plastic sealed in the Al laminated film and between the film and the foamed plastic, i.e., gap, possesses an unsaturated group, such as isoprene. Thus polymerization may occur by irradiating with electron rays, and the inside of the foams and the gap region may be reduced in pressure while the bag of the laminated film retains its shape.

  • Patent number: 5891579
    Abstract: Fixtures composed of a combination of a metallic core coated with a fused plasticized vinyl chloride coating and an overcoating barrier which shields the coating from atmospheric exposure possess superior resistance against outdoor weathering. The overcoating barrier protectively shields the plasticized vinyl chloride coating from microbiological and sunlight induced degradation. The fixture maintains the compositional integrity and appearance of a freshly manufactured fixture notwithstanding prolonged exposure to normally deteriorative weathering (e.g. bright sunlight, hot and humid) conditions. If desired, the protective barrier may include tractive imparting components which prevent slippage and improve upon surface traction. Thermosetting resins and especially the electrostatically applied powders particularly afford effective overcoating barriers for protectively shielding the plasticized vinyl chloride coating from degradation.

  • Patent number: 5877895
    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.
