Overview of Recent Developments in Composite Epoxy Resin in Organic Coating on Steel (2020-2024)

Jianghua Hao et al. Materials (Basel). .

Abstract

Epoxy resin, widely recognized for its excellent performance, is extensively applied in the anti-corrosion field of steel. Continuous enhancement of the anti-corrosion performance of epoxy resins to satisfy more stringent requirements has become a current hot topic of interest in both scientific and industrial circles. This review focuses on recent advancements in composite epoxy resin coatings for steel from 2020 to 2024, emphasizing improvements in anti-corrosion performance through various additive modifications. Modification methods are categorized into metal-based compounds, organic compounds, organometallic compounds, and carbon-based materials. To assist scholars in understanding the latest research advancements, key findings from electrochemical tests, mechanical assessments, and structural characterizations are summarized, highlighting their influence on corrosion resistance, adhesion, mechanical properties, and self-healing capabilities.

Keywords: anti-corrosion performance; epoxy coating; modification; steel.
