Anti-corrosive performance of epoxy coatings containing various nano-particles for splash zone applications
Various formulations of epoxy nano-composites coating were developed by incorporating the nanoparticles
(NPs) of ZnO, ZrO2, and SiO2 (2 wt%) in commercially available epoxy resin as the matrix phase. Direct incorporation
method was used for the addition of NPs in epoxy matrix. High-speed mechanical stirring and ultra-sonication
were carried out to facilitate the dispersion of NPs in the presence of acetone used as a solvent. Coating of neat epoxy
and NPs (ZnO, ZrO2, SiO2) doped coating was applied on mild steel substrate for corrosion analysis. The effect of the
incorporation of various NPs on anti-corrosive properties of the epoxy/nano-composite coatings was investigated by
electrochemical impedance spectroscopy technique. The experimental results showed an improvement in the anticorrosive
properties for EZr coatings as compared with pristine and other nanocomposite coating samples.
