［Purpose/Significance］Epoxy zinc-rich coatings（EZRCs）are extensively employedin the field of marine heavy-duty anti-corrosion. They play a crucial role in extending the service life ofmarine engineering facilities and reducing maintenance costs.［Analysis/Comment/Progress］ This article introduces the definition，relevant standard systems，and anti-corrosion mechanisms of EZRCs. It further provides an in-depth analysis of recent research progress aimed at enhancing EZRCperformance through strategies including the incorporation of conductive materials，pigments and fillers，and surface modification of zinc powder.［Conclusion/Prospect］ EZRCs exhibit promisingprospects within the marine heavy-duty anti-corrosion domain. However，advancing core mechanistic understanding，refining synergistic studies of coating systems，and improving compatibility with testingstandards are imperative. Future development will focus on advancing green and environmentallyfriendly formulations，enhancing long-term anti-corrosion efficacy，and improving environmentaladaptability to meet the stringent anticorrosive demands of marine engineering application.
