| Résumé : |
High performance coatings : A low molecular weight, alkyd-based waterborne anticorrosive coating was formulated with resin : cross-linker ration of 70:30. The coating was modified with nano-Zn0 particles as pigments in different concentration (0.0.1 %, 0.02 % and 0.03 % by weight) to form a nano-composite coating. The nano-Zn0 modified composite coatings were applied on mild steel substrate by dipping. The coated panels were subjected to various test environments like salt spray, humidity and UV-weathering. The improvements in electrochemical performance of the composite coatings were evaluated using various analytical techniques like scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The result showed that, with increase in the concentration of nano-Zn0 there was an improvement in the corrosion resistance and UV resistance of the coatings indicating the positive effect of addition of nano-Zn0 particles to the coatings. |
