The diamine-based polybenzoxazine (PpC-mda) coating was prepared on mild steel (MS) by spray coating and thermal curing method. The thermal curing process and thermal stability of PpC-mda were studied by differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA), respectively. The corrosion resistance properties of PpC-mda coating were investigated by electrochemical measurements. The results revealed that the hydrophobic PpC-mda coating exhibited high corrosion resistance on mild steel with the protection efficiency of 99.93%.
