This paper describes the protective properties of water-based VCI (Volatile Corrosion Inhibitors) modified acrylic film intended for the temporary protection from corrosion of carbon steel equipment during transportation and storage in the open air. The protective properties of water-based VCI modified acrylic film were studied by means of electrochemical methods and compared under outdoor atmospheric industrial conditions. The polarization curves showed that the VCI compound investigated was of the anodic type. The steel panels coated by the water-based VCI modified acrylic system of various film thickness (O-25 microns) were examined under atmospheric oil refinery industrial conditions. This examination showed that these films protect the carbon steel surfaces for at least 10 months.
