The polyurethane coatings containing phenylsilane groups (PU-S) were prepared by using the hydrolyzed triethoxyphenylsilane (TEPS). The synthesized PU-S coatings were characterized by Fourier Transform Infrared (FTIR). Mechanical properties and contact angle of PU-S coatings with different TEPS concentrations (1 %, 5 % and 10 %) were also studied. Electrochemical impedance spectroscopy (EIS) and salt spray test were carried out to evaluate corrosion resistance and the macroscopic failures of the coatings. The results show that the presence of TEPS in polyme matrix improved mechanical properties and corrosion protection performance of polyurethane coating.
