Results of Potentiodynamic Polarization Study

The polarization study was performed for specimens after 90 days of immersion in 3% NaCl solution. It was observed that the polarization response of siliconized epoxy systems 

The shift of polarization response towards the anodic side for sihconized epoxy systems is due to the inherent hydro-phihc nature of sihcone, which restrained the permeabihty of water and other corrosive species by offering high corrosion resistance, and hence low values of corrosion current Thus the sihconized epoxy coating systems have the abiUty to withstand adverse corrosive environment for a longer duration irrespective of the curing agents employed. However, the neat epoxy coating systems absorb moisture, which in turn
