Shielding metals effectively: Progress in epoxy resin coatings for corrosion protection. Source: §Á§ß §©§Ñ§Ò§à§Ý§à§ä§ß§Ú§Û - adobe.stock.com

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.

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.
