This work intends to study the effect of epoxy silicon resin mixture ratio with aminosilane hardener on corrosion protection properties of the coating. Coatings with different mixture ratio ranging 15-50% resin: hardener were prepared and cured for 1 h at 120 °C. To evaluate corrosion protection properties, electrochemical impedance spectroscopy (EIS) was employed after 240 h exposure of samples to salt spray. In addition, pull-off adhesion strength was measured after salt spray exposure. Results showed deterioration of protection properties and adhesion strength of the coatings below and above 20% mixture ratio. According to the tests results, the optimal mixture ratio of epoxy silicon to aminosilane was 20%.
