Corrosion can be protected by the application of protective coatings developed by organic resins. Metal loss due to corrosion affects a country’s economy significantly. Organic coating is the most economical method for corrosion prevention. Silicone and polyester resins have good physical, mechanical, and anticorrosive properties, and can be blended to form hybrid networks. This study develops coatings using various resin concentrations and evaluates their adhesion through cross hatch tests and anticorrosion properties via Electrochemical Impedance Spectroscopy (EIS). FTIR was used to identify the crosslinking. Results show that coatings with 40–60% polyester demonstrate superior adhesion and resistance, maintaining protection for over 30 days in corrosive environments.
