Title:

SURFACE-TREATED STAINLESS STEEL SHEET AND RUBBER-COATED STAINLESS STEEL SHEET FOR GASKET

Document Type and Number:

Japanese Patent JP3895203

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a stainless steel gasket which shows an excellent sealing property and durability, exhibits no decrease in adhesion between stainless steel and a rubber coating layer over a long period of time and provides no adverse effect to the environment.
SOLUTION: A surface-treated stainless steel sheet for the gasket has an organic-inorganic composite coating film comprising a titanium compound, a fluorine compound and a phenol resin which partially or entirely covers the stainless steel sheet surface and an adhesive layer comprising a phenol resin which is formed on the organic-inorganic composite coating film. Preferably, the organic-inorganic composite coating film is formed to yield a dry coating weight of 20-200 mg/m2 and may further comprise a zirconium compound. A rubber-coated stainless steel sheet for the gasket has the rubber coating layer comprising a phenolic resin which is formed via the organic-inoganic composite coating film or the adhesive layer comprising the phenolic resin.
