Enhanced anticorrosion performance of zinc rich epoxy coatings

In a recently published study, the effect of a partial replacement of spherical zinc particles by stainless steel flakes (SSF) on the corrosion protection performance of a zinc-rich epoxy (ZRE) coating was studied. Salt spray test, open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarisation tests were utilised to evaluate the anticorrosion performance of the coatings.

The results demonstrated that a partial replacement of zinc particles by SSF enhanced the anticorrosion properties of the ZRE coating, and the enhancement was attributed to the synergistic effects by increasing the coating impedance and extending the cathodic protection duration.
The study was published in Progress in Organic Coatings, Volume 163, February 2022.
