Due to the pressure of environment protection regulation, the isocyanate-free polyurethane coatings (NIPU) have received extensive attention. However, the anti-corrosion performance of NIPU has not been well studied yet. The aim of this work is developing anti-corrosion NIPU organic/inorganic hybrid coatings by incorporating polysiloxanes. In this study, electrochemical impedance spectroscopy (EIS) and salt spray (ASTM B-117) were applied to compare the anti-corrosion performance of NIPU and modified NIPU. Scanning electron microscope (SEM) was used to observe the microstructure of NIPU surface. Further study will focus on the anti-corrosion mechanism of NIPU organic/inorganic hybrid coatings.
