Abstract:

The purpose of this work was to determine the environmental resistance of rubber-to-metal vulcanized bonds and to develop the means of predicting this environmental resistance through accelerated testing. Four commonly used elastomers were vulcanized-bonded to steel and aluminum substrates. Butadieneacrylonitrile and ethylene propylene terpolymer rubber-to- metal vulcanized bonds showed a severe loss in bond strength in long-term environmental exposure and in accelerated testing. Butadienestyrene and neoprene rubber-to-metal vulcanized bonds showed no significant loss in bond strength in long-term environmental exposure or in accelerated testing. Thus a degree of correlation between the results of long-term outdoor tests and short- term accelerated tests was established.
