Abstract

Epoxy resins have many advantages over other binders in the fonnulation of primers to protect steel structures from various corrosive environments. Recent studies showed that inhibitor incorporated epoxy primers protect structures for longer duration than plain epoxy primers. In the present investigation, different concentration of dicyclohexylamine nitrite (DCHAN) (0.5-2%) were incorporated in epoxy primers and coated on steel surfaces. The perfonnance of the primers were evalauted by salts spray and electrochemical evalaution tests in 3% sodium cWoride solution. The perfonnance of the primer in presence the inhibitor showed that the inhibitor protected the steel surface for a particular period and thereafter the inhibitor efficiency was in decreasing trend. In this study, the ratios of the DCHAN was optimized in the epoxy resin based primer and the performance of the optimized primer was evaluated by accelerated and electrochemical techniques.
