A metal gasket material plate includes a sealing layer formed by layering a chemical coating layer, an adhesive layer, and a rubber coating layer in this order on at least one side of a metal plate. The chemical coating layer is formed by a thermosetting surface preparation agent including inorganic compound particles and a metal alkoxide compound. The adhesive layer is formed by an adhesive including an epoxy compound and an anti-corrosive pigment. The rubber coating layer is formed by a rubber agent including rubber.

Metal gasket material plate and method for manufacturing the same

The resin-coated sand is produced by coating the surface of a refractory granular aggregate with a thermosetting resin and a thermoplastic resin. When using this resin-coated sand, a mold with a less rough surface can be produced by a RP molding apparatus. When using this mold made of the resin-coated sand, a casting with fewer gas defects can be produced.
