Subjects:	Corrosion resistance, Surface coatings, Carbon dioxide, Raw materials, Sealing compounds
Abstract:	Polymer materials are widely used in various industrial fields and serve as effective corrosion-resistant coatings. However, their performance in complex high-temperature, highhumidity corrosion environments remains to be evaluated. This study selected four mature corrosion-resistant coating systems from different manufacturers as test samples (MN-1 to MN-4) and prepared four test panels according to the coating requirements of each system. Concurrently, methods for pore analysis, corrosion resistance testing, and durability assessment of corrosion-resistant coatings were designed, forming the primary experimental research methods. The changes in the adhesion resistance to chlorine, sulfate ions, and carbon dioxide ions of the coatings on the surfaces of MN-1 to MN-4 under high-humidity conditions were compared to evaluate the overall corrosion resistance performance of the four coatings. Based on the corrosion resistance capabilities of the four coatings, a polymer sealant was prepared using a combination of raw materials. The six samples of the designed polymer sealant maintained an overall material weight within the range of 0.025-0.035 g under high-temperature and humid conditions, demonstrating strong resistance to aging.
