Anticorrosive polyester based composite coatings on mild steel applied to mixed acid storage tank containing varying compositions of Sulfuric Acid, Nitric acid provide anticorrosive solutions. These coatings are capable to inhibit the redox reactions. In consideration of above, the purpose of present work is to prevent corrosion on mixed acid storage tank through application of appropriate polyester coatings on their surface and structures that will be used in chemical industries where these acids are being stored. In this project, the surface of mild steel was coated by protective polymer coatings. Lab scale storage tanks of mild steel were coated with anticorrosive (fiber reinforced laminate-vinyl and fiber reinforced laminate palatal p-4). Various coatings compositions were explored based on esters. Electrochemical Impedance Spectroscopy (EIS), Gamry Potentiostat Tafel Scan analyses tools were used and Scanning Electron Microscopy (SEM) was conducted to investigate the surface morphology of these coatings. The applied polymer based composite coatings provided excellent corrosion resistance in both Laminate palatal fiber reinforced (LAM-P/FR) and laminate vinyl fiber reinforced (LAM-V/FR) coatings condition and reduction in corrosion rate. These bespoke coatings can be widely used to protect mild steel structures which are usually acid storage tanks and are used in various chemical industries with acidic environment. The study estimated that 25 to 30% of annual corrosion costs could be saved as well as production increases if these corrosion protection coatings were employed.
