An Enhanced Corrosion Protection Mechanism for Rubber-to-Metal Bonding
By Tony Hall, Greenkote USA and Jacob Adams, Kalcor Coatings Company
The trend toward more stringent performance requirements for many transportation and industrial applications poses a significant and potentially costly problem for elastomeric bonding to various metal substrates. This paper addresses a new process which enhances the long-term corrosion characteristics of rubber-to-metal bonded components while improving bond strength at the same time.
This paper details new results of a novel thermo-diffusion coating that works by Thermo-Chemical Surface Modification(TCSM) . This diffusion process forms a protective layer that partially diffuses into the substrate and cannot be separated by physical or environmental testing. Following surface modification, application by spray, dip, or dip-spin of an engineered waterborne air-dry/low-bake coating adds additional functionality; yielding over 2000 hours of salt spray corrosion with no visible evidence of rust or oxidation.
The system is ideal for rubber to metal bonding applications since the material provides superior bond strength with decreased potential for failure, while offering better overall appearance and part performance in an environmentally friendly rubber-to-metal bonding system.
