Method for bonding polyamide resin and fluoroelastomer

摘要

A bond between fluoroelastomer and polyamide resin is established by applying a silane-based primer composition to a surface of polyamide resin, heat treating at 100-200°C, applying a liquid fluoroelastomer composition to the primer coat at room temperature to 100°C, and heat curing at 100-200°C for bonding the fluoroelastomer to the polyamide resin. The bond between fluoroelastomer and polyamide resin is maintained over a long period of time even in transmission oils.
