METAL GASKET MATERIAL PLATE AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide de-chroming processing material capable of improving a adhesive property of a rubber layer adhered to a metallic plate by fretting and antifreeze through a primer layer and an adhesive layer, preventing the rubber layer from easily peeling off from the metallic plate, and considering environment and the human body. SOLUTION: In this laminated metal gasket material plate 1 made by providing a rubber layer 5 on a stainless steel plate 2 through an adhesive layer 4, primer layer 3 of a silica-alumina condensation product is formed on a surface of the stainless steel plate 2.
