In this study, a commercial epoxy resin (KER 828) was employed as the organic component of the organic inorganic hybrid coating to enhance corrosion resistance while reducing production costs via the sol-gel method. Hybrid coatings were formulated with varying weight percentages and subsequently applied to 304 stainless steel substrates to assess their effectiveness against corrosion. The Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), pull off test and water contact angle (WCA) techniques were employed to characterize the obtained coatings. The corrosion behavior of both the uncoated stainless steel and the coated samples was evaluated through Potentiodynamic Polarization test. Additionally, the electrochemical impedance spectroscopy (EIS) analysis was employed over time intervals of 1 h, 1 day, 1 week and 1 month exposure to 3.5 wt% NaCl solution. The results demonstrated that coatings with equal weight percentages of the organic and inorganic phases (1:1:1) exhibited the highest corrosion resistance, which can be attributed to the enhanced Si-O-Si network formation.
