Abstract

Corrosion can be protected by the application of protective coatings developed by organic resins. Metal lose due to corrosion affects a country economic to a higher extent. Organic coating is the cheapest method to prevent corrosion. Silicone and polyester resins have good physical, mechanical and anticorrosive properties. They can be blended and made hybrid networks. Various concentrations of the two resins were mixed. The curing agent used in the study was polyisocyanate. The network of different functional groups between silicone and polyester resins was examined by FTIR spectroscopy. The crosslink formation between the resins was observed by the identification and analysis of NH bond, Si-O-Si, Si-O-C functional groups.The developed coating systems have got adhesion property which was evaluated by cross hatch test. Electrochemical Impedance Spectroscopy (EIS) was used to study the anticorrosion property of the systems by exposing the samples to 3% NaCl solution. EIS experimental results show that the coatings could protect the metal surface for the exposure to corrosive medium for more than 30 days.
