［Objective］ To address the urgent demand for high-performance anti-corrosion coatings inside storage tanks and pipelines，a solvent-free anti-corrosion lining coating was developed.［Methods］This coating was formulated using low-viscosity phenolic epoxy resin as the primary film-forming material. Functional reactive diluents were incorporated to reduce the system viscosity，and a modified aliphatic amine was selected as the curing agent.［Results］The prepared coating exhibitedexcellent adhesion and strong wear resistance for the high cross-linking density. Furthermore，it demonstrated outstanding resistance to chemicals，salt spray，acids，alkalis，and organic solvents， fulfilling the protection performance requirements of the inner wall of storage tanks and pipelines undercorrosive environments.［Conclusion］As a solvent-free system，the coating emits extremely low levels of VOC during production and construction，aligning with environmental protection，green and low-carbon requirements.
