“…Most authors agree that for Zn pigmented epoxy coatings when speaking about the coating system the electrochemical mechanism can be considered as rather the last instance in terms of protection if Zn content in dry coating is lower than 80% wt. [1]. That is why very often different types of fillers are tested for partial replacement of Zn in this type of coatings with the aim to improve their performance changing from sacrificial protection into dominating barrier protection.…”

The possible effects on the protective performance of ZRP modified by combination of Zn dust with aluminium or carbon type fillers were investigated using electrochemical noise analysis (ENA). The role of different oxygen diffusion characteristics (identified on tested coating systems with ENA) on delamination tendency was tested during 168 hrs immersion tests in 0.05 M NaCl. It was shown the protective performance of tested type of coating systems can be changing with immersion time rather differently in relation to different ability of polymer matrix with the Zn/Al or Zn/C particles combination for oxygen transport to the coating/steel interface.

“…A high volume fraction of metallic pigments is required to ensure good electrical contact between the metal particles and the matrix. For example, the Zn content in Zn-rich primers must exceed the critical pigment volume concentration (CPVC) value of 30-45% [35]. Furthermore, dissolving metal particles leave behind voids or channels in the primer for moisture ingress.…”
