Surbond is Metal Tech’s solid core laminate series. It features a thermal-set, adhesively bonded laminate with excellent resistance to many fluids. Bond strength and quality are excellent and a variety of grades are available. Using solid core metal, generally carbon steel, the facing material is chemically bonded in our exclusive process. The result is a robust material for fluid gasket applications. Surbond provides steel reinforcement for rigidity in the fabrication and handling of the gasket as well as long-term performance in the completed joint. Additional stiffness provided by the metal core makes a good gasket even better.
