Polymeric coupling agent for bonding polymers to aluminum
- Univ. of Connecticut, Storrs, CT (United States)
A polymeric coupling agent, containing {beta}-dike tone and epoxy functional groups, is being evaluated as a potential adhesion enhancer and corrosion inhibitor to be utilized on adhesively bonded aluminum substrates. X-ray Photoelectron Spectroscopy studies indicate chemical interaction of the coupling agent with the aluminum oxide surface. Modified tubular butt joints were utilized to evaluate the joint strengths and durabilities of coupling agent treated joints. Dry strengths of treated joints were comparable to untreated controls, however after 3 and 5 days immersion in 57{degrees}C water, the coupling agent treated joints displayed improved joint strengths as compared to the untreated controls. Comparisons of coupling agent treated and untreated aluminum substrates after 24 hours exposure to salt spray (ASTM B117) indicated improved corrosion resistance due to the coupling agent treatment.
