Metal gasket raw material plate and manufacturing method therefor
There is provided a non-chromium treated material in which peeling resistance between a metal plate and a rubber layer via a primer layer and a bond layer, which is decreased by fretting and antifreeze liquid, can be improved, the rubber layer is less liable to peel from the metal plate, and the material has little effect on the environment and human body. In a metal gasket raw material plate 1 of a laminated form in which a rubber layer 5 is provided on a stainless steel plate 2 via a bonding layer 4, a primer layer 3 of a silica-alumina condensate is formed on the surface of the stainless steel plate 2.
