[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.
