Title: NITRILE RUBBER/METAL MULTILAYER MATERIAL FOR GASKET
Abstract:
A nitrile rubber/metal multilayer material for gaskets which is obtained by successively superposing a layer of a surface-treating agent comprising a zirconium-containing compound, a phosphorus-containing compound, and silica, a layer of a vulcanization adhesive, and a nitrile rubber layer. Even in the case where this nitrile rubber/metal multilayer material for gaskets is a multilayer structure including a metal sheet such as, for example, SPCC or SPFC, and the nitrile rubber, the material for gaskets shows sufficient adhesiveness in an actual use environment for gaskets even when immersed in or exposed to a long-life coolant (LLC). The material for gaskets further has excellent heat resistance.
