Abstract : A method of preparing nitrile elastomer surfaces for bonding by epoxy adhesives is presented. A treating solution comprising a dilute concentration of a mineral acid such as HCL in a carrier comprising water and either alcohol or ketones is prepared. The treating solution is applied to the elastomer surface with the surface being hydrolyzed in a mild manner therby providing an improved adherable surface for covalent bonding by epoxy adhesives. A surfactant can be added to the treating solution for cleaning the surface to enhance the surface treatment.
