を払うことが重要である。Among the various performances required for automobile gaskets,
Sealing performance and durability are particularly important, but in the case of metal gaskets, the quality of these performances often depends on the adhesion between the rubber layer and the rubber coated metal plate that is the gasket's substrate. Therefore, when manufacturing rubber-coated metal, it is important to increase the adhesive strength of the rubber layer to the metal plate and to take care not to reduce the adhesive strength under the usage conditions.

がすぐれていると判断することができる。Test methods for evaluating the performance of rubber coated metals include the Erichsen test, water resistance test, antifreeze resistance test, salt water resistance test, and oil resistance test. Furthermore, the sealing performance and durability, which are important for the practical performance of metal gaskets, are mainly influenced by the long-term adhesion between the metal plate and the rubber layer. For this reason, as a durability test method for automotive metal gaskets, the rubber coated metal substrate product is often subjected to hot water durability tests and antifreeze durability tests to confirm the long-term adhesion of the rubber layer. It can be judged that the longer the time until the rubber layer peels off, the better the long-term adhesiveness is.
