METAL GASKET MATERIAL SHEET

摘要

A metal gasket material plate has improved adhesion of a rubber layer to a metal plate by use of an adhesive layer, so as to prevent the rubber layer from happening delamination of the metal plate and to provide a chromium-free material plate in consideration of adverse effects on the environment and a human body. In a laminated metal gasket material plate provided with a rubber layer on a metal plate by use of an adhesive layer, the metal gasket material plate includes silane-based chemical conversion coating being formed between a surface of the metal plate and the adhesive layer by applying a silane coupling agent containing any of an epoxy group, a mercapto group, and an amino group as a functional group. Here, the adhesive layer is made of a phenol resin-based adhesive, and the rubber layer is made of an NBR-based rubber mixture.
