Abstract: A sealing gasket for closure, made of a polyurethane elastomer obtained by reacting the following (A), (B) and (C): (A) a polyisocyanate component having an isocyanate group content of 5 to 38% by weight and average 2 to 3 functional groups, obtained by modifying an aliphatic isocyanate and/or an alicyclic isocyanate, (B) a polyol component having a hydroxyl value of 20 to 350 mgKOH/g and average 2 to 3 functional groups, and (C) a glycerin fatty acid ester having hydroxyl group(s); and a process for producing a closure using such a sealing gasket. The closure sealing gasket made of a polyurethane elastomer, obtained by the present invention, when used for a closure (e.g. a metal closure of a food container having good sealing properties), is little eluted, is less in swelling with an alcoholic beverage and less in the absorption of the odor of the alcoholic beverage into the closure sealing gasket, and is tough, and causes no yellowing.

Abstract: A storage battery which can further intensify the sealing properties of the electrode rod piercing portion thereof, a technique capable of increasing the area of the sealing surface at the sealed portion of the storage battery, a technique capable of certainly preventing the missing of mounting of a rubber-based sealing material corresponding to O-ring at the sealed portion of the storage battery, and an insulating material having an excellent corrosion resistance to highly corrosive battery content and a battery container including same are provided. An electrode rod 14 is allowed to extend upward through an annular member 15, a pressing member 18 is placed on the annular member 15, and a nut 22 is then threaded on a thread portion 21. This threading job is effected until the pressing member 18 is placed on and stopped by a collar portion 23. At the time when threading ends, a neck portion 25 is somewhat compressed to exhibit sealing properties.

Abstract: A sealing member for a cap featuring excellent cap performance as well as excellent safety and environmental friendliness, and a metallic cap. A foamed polyurethane elastomer having a JIS A hardness of from 15 to 65 and a foaming magnification of from 1.1 to 10 times is used as the sealing member so as to obtain excellent sealing performance, durability, safety and environmental friendliness. The sealing member is provided for a metallic cap shell that has a polyester film formed on the inner surface of the cap, thereby to obtain a cap featuring excellent sealing performance, durability, safety and environmental friendliness.

Abstract: An object, such as a container cover, is lined on a predefined area of the object by depositing powder on the predefined area. The lining material is formed into a non-spherical powder having a resting angle of 40 degrees or greater. The powder is deposited by fluidizing the powder in a feeder using vibration and conveying the powder through a nozzle to the predefined area. The powder layer deposited on the object is pressed with a molding element to form a lining layer having the predefined shape. The lining thus formed has a predefined thickness distribution and shape with good tightening and sealing properties and corrosion resistance. In addition, no environmentally unsafe processes are required for the precise deposition of powder.

Abstract: An aqueous paint which exhibits improved dispersion property in the water and dispersion stability, has a low viscosity enabling the painting operation to be efficiently carried out, and cures at low temperatures within short periods of time to form a coating which after cured exhibits high degree of workability, high corrosion resistance, and elutes out little into the content. The aqueous paint comprises an epoxy acrylate resin prepared by modifying, with a (meth)acrylic monomer, a copolymerized epoxy resin having a number average molecular weight of 8,000 to 15,000 and containing, as phenolic components, a bisphenol-A component and a bisphenol-F component at a molar ratio of from 5:5 to 8:2, and a curing agent of a thermosetting resin having a methylol group.

Abstract: An adhesion structure in which the gel of an acrylic plastisol is strongly adhered to the metallic base material, featuring excellent resistance against corrosion and exhibiting small whitening tendency even under severe conditions for treatment with hot water such as retort processing, and a method of producing the same structure. The acrylic plastisol is applied onto the metallic base material or onto the metallic base material having an organic coating provided with a layer of a thermosetting resin which contains a bisphenol-type epoxy resin and a phenolic resin at a weight ratio of from 99:1 to 85:15, and is gelled by heating and is, at the same time, adhered to the base material via the thermosetting resin layer. The acrylic plastisol is gelled and is strongly adhered onto the thermosetting resin layer within short periods of time. The obtained adhesion structure exhibits excellent resistance against peeling, corrosion and retorting.

Abstract: An acrylic resin plastisol composition that forms coatings or molded articles having excellent anticreep property. The plastisol composition maintains excellent fluidity required for the coating and molding even after preserved for extended periods of time and further exhibits excellent gelation property upon heating, enabling the obtained coating or the molded article to exhibit excellent resistance against the relaxation of stress. The plastisol composition comprises a dispersing medium composed chiefly of a plasticizer and acrylic resin grains dispersed in said dispersing medium, wherein said acrylic resin grains have a functional group selected from the group consisting of carboxyl group, hydroxyl group, epoxy group, methylol group and etherified methylol group, and said dispersing medium contains a crosslinking agent that has reactivity to said functional group in a state of being at least partly solubilized in said dispersing medium.

Abstract: An o/w water paint having excellent dispersibility and stability is prepared according to a phase conversion process comprising adding ammonia or an amine and water to a solution of an epoxy resin, a hardener resin, and an acrylic resin in an organic solvent or to a molten mixture of these resins to neutralize the acrylic resin. In view of adhesion of a coat to metal and workability, branched alkylamines or heterocyclic amines are suitable as the neutralizing amines. In applying this paint, steam optionally containing fine water droplets is preferably applied to a wet coat prior to drying. Furthermore, a process for the continuous production of an emulsion type water paint comprising a carboxyl group-containing acrylic resin component, an epoxy resin component and a curing agent resin component for the epoxy resin is disclosed.
