| Résumé : |
In the present study, the efficacy of Fluoro Ethylene Vinyl Ether (FEVE) on the performance of Polyurethane coating was investigated. A series of Polyurethane (PU)/ FEVE hybrid coatings were formulated by incorporation of 2%, 5%, and 10% concentrations (by weight) of FEVE into PU coating. The structural characterization was done by ATR Fourier transform infrared spectroscopy (FTIR) spectroscopy. The prepared PU/FEVE hybrid coatings were casted on Teflon Petri dish and dried films were used to measure extent of water absorption and water vapor permeability. The prepared PU/ FEVE hybrid coatings were also applied on mild steel substrates. The ageing behavior of coated panels was evaluated by QUV Wheather-o-meter and gloss meter. The surface morphology, contact angle and corrosion resistance of coated panels were evaluated by Atomic Force Microscopy (AFM), Goniometry and Electrochemical Impedance Spectroscopy (EIS) respectively. Performance results suggest that, with increasing the concentration of FEVE, the performance of PU coating increases. |
