  • Patent number: 8846809
    Abstract: A urethane adhesive composition includes a first liquid and a second liquid, the first liquid containing a prepolymer obtained by reacting a polyisocyanate and a high-molecular-weight polyol (I), and at least one filler selected from talc and calcium carbonate, and containing 20 parts by mass or more of talc, 0 to 40 parts by mass of calcium carbonate, and 10 parts by mass or more of zeolite based on 100 parts by mass of the polyisocyanate, the high-molecular-weight polyol (I), and the prepolymer in total, the second liquid containing a high-molecular-weight polyol (II) and a low-molecular-weight polyol, the ratio of the number of moles of hydroxyl groups derived from the low-molecular-weight polyol to the total number of moles of hydroxyl groups derived from the high-molecular-weight polyol (I) and the high-molecular-weight polyol (II) being four or more.

  • Publication number: 20130030085
    Abstract: Provided is the one-pack type backing resin composition which exhibits excellent fall-off resistance, excellent storage stability, and high flame retardancy. A one-pack type backing resin composition includes 100 parts by mass of (A) a (meth)acrylic polymer, and 50 to 500 parts by mass of (B) a flame retardant, the (meth)acrylic polymer (A) being produced by emulsion polymerization of a monomer component, and having a solvent-insoluble content of 0 to 85 mass %, the monomer component including 0.5 to 25 mass % of (a) glycidyl methacrylate, 0.2 to 10 mass % of (b) an unsaturated carboxylic acid monomer, and 70 to 99.3 mass % of (c) an additional copolymerizable monomer (provided that (a)+(b)+(c)=100 mass %).

  • Patent number: 8163120
    Abstract: A process for producing an IC card comprising: an application/bonding step of applying an adhesive having a curing rate ratio (80° C./40° C.) of 30 or more on the surface of an inlet film, on which a number of IC modules are mounted, and/or a skin film for covering at least one surface of the inlet film, and bonding the inlet film and the skin film together to form a laminate film; a curing step of curing the adhesive to form a cured resin layer between the inlet film and the skin film of the laminate film; and a card forming step of forming a number of IC cards by dividing the laminate film for each IC module.

  • Patent number: 6706800
    Abstract: A method of backing a carpet, comprising the steps of applying, to the back of a carpet, an aqueous emulsion composition prepared by adding a polyisocyanate compound to a specific high-solid-content emulsion compound, laminating a fabric to the composition-applied surface of the carpet, and thermally curing and then drying the emulsion composition applied; and a carpet backed by this method. The aqueous emulsion composition for use in this method is highly safe and easy to handle. Moreover, even when this emulsion composition is applied to the back of a carpet to a thickness of as great as 1 mm or more, it is cured and dried in a short time. The shortcomings in the conventional methods using aqueous emulsions can thus be successfully overcome by this method.
