Corrosion remains a major challenge for metal infrastructures. A recent review highlights the effectiveness of epoxy resin (ER) and epoxy phenolic resin (EPR)-based coatings in protecting steel and aluminum surfaces.

Incorporating compounds like zinc oxide, titanium dioxide, silicon dioxide, carbon nanotubes, and graphene oxide further enhances the coatings’ performance. However, coating failures due to surface pores allow corrosive species to compromise the structure.


Reading tip: Epoxy resins

Due to their outstanding properties, epoxy resins are more widely used in the coating industry than almost any other class of binder. In their new reference book “Epoxy Resins“, the authors Dornbusch, Christ and Rasing explain the basics of the chemistry of the epoxy group and use specific formulations to explain the use of epoxy and phenoxy resins in industrial coatings – including corrosion protection, floor coatings, powder coatings and internal can coatings.


Despite over a century of research, the mechanisms behind coating degradation continue to be studied. This article consolidates advancements, explores failure mechanisms, and provides insights into future predictive formulation strategies for corrosion protection.
