摘要： A method for electroplating a zinc-iron alloy from an alkaline bath which comprises electroplating a zinc-iron alloy on a metal surface from an alkaline zinc plating bath having a pH of at least 13.0 and containing 0.02 to 5 g/liter of iron solubilized with a chelating agent, thereby to form on the metal surface a zinc-iron alloy layer having excellent corrosion resistance containing 0.02 to 20% of iron based on the total weight of the deposited metal.

摘要： A sealing gasket for closure, made of a polyurethane elastomer obtained by reacting the following (A) and (B):(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, and(B) a polyol component having a hydroxyl value of 20 to 350 mgKOH/g and average 2 to 3 functional groups; 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 food container), causes no yellowing by ultraviolet light, has a strength at least equal to those of sealing gaskets produced from an aromatic isocyanate.
