Abstract: The present invention includes an electrical steel sheet with an insulation coating having a large interlaminar insulation resistance when laminated; a coating material for forming the insulation coating that is used for the electrical steel sheet and the coating material for forming the insulation coating, which includes apart from a solvent an aqueous carboxy group-containing resin as component (A), an aluminum-containing oxide as component (B), and at least one crosslinking agent as component (C) selected from the group consisting of melamine, isocyanate and oxazoline. There are component (A); 100 parts by mass; 40 parts by mass<component (B)<150 parts by mass; 20 parts by mass<component (C)<100 parts by mass.

Abstract: A stain resistant laminated sheet material is provided which comprises: a base fabric; a stain resistant resin layer provided on at least one side of the base fabric; and a color layer provided on the stain resistant resin layer. The color layer is soluble in a particular solvent in which the stain resistant resin layer is insoluble.

Abstract: A corrosion resistant coating composition comprising (i) 100 parts by weight of a bisphenol type epoxy resin comprising bisphenol skeletons and epichlorohydrin skeletons and having at least two epoxy groups per molecule, said bisphenol skeletons comprising bisphenol A skeletons and bisphenol F skeletons in a weight ratio of from 95:5 to 60:40, and (ii) from 5 to 400 parts by weight of silica particles.

Abstract: A method and device are provided for separating trimming losses from a sheet having a plurality of products formed thereon with star-shaped scraps between the products. In one embodiment, the sheet is placed on a sheet supporting plate. The sheet is positioned between a blanking plate and a plurality of pushing rods fixed to a mounting plate. Each of the pushing rods has a piercing pin extending from the free end thereof for penetrating into a corresponding star-shaped scrap. The blanking plate has through holes formed therein which correspond to the pushing rods and star-shaped scraps such that the pushing rod passes through a corresponding through hole. The inner diameter of each through hole is smaller than the outer size or greatest dimension of the star-shaped scrap. When the star-shaped scrap is pushed through the through hole by the pushing rod, it deforms and passes through the through hole.
