Sulfonated polyethylene anti-corrosion primer (often called chlorosulfonated polyethylene anti-corrosion primer) is a two-component solvent-based rubber-based anti-corrosion primer. It uses chlorosulfonated polyethylene resin as the main film-forming agent, and is made with anti-rust pigments and fillers, modified resins, vulcanizing agents and special solvents. It is cured at room temperature without baking. The core value is elastic weather resistance, high and low temperature resistance and strong chemical anti-corrosion. It is suitable for - 40℃ to 120℃, containing acid and alkali salts / It is used for the bottom layer protection of steel/concrete substrates in heavy corrosive environments of chemical atmospheres. It can withstand substrate deformation and hot and cold shocks, and provides long-term physical shielding and chemical rust prevention. Core features: weather and chemical resistance, adaptable to extreme working conditions, strong Two-component cross-linking adhesion, flexible construction and high efficiency at low temperature limitations and adaptations Contains volatile solvents, construction requires strong ventilation protection; it needs to be mixed in proportion and used up within the activation period (usually 8 hours); it has average adhesion to zinc-based substrates and does not require direct application of zinc-rich coatings, and is more suitable for steel and concrete substrates. Scope of application Chemical industry/petrochemical industry: bottom protection of highly corrosive equipment such as reactors, storage tanks, pipelines, acid-base tanks, etc. Ocean/Port: Seawater and salt spray corrosion-resistant scenarios such as offshore platforms, wharf steel piles, and ship ballast tanks. Municipal/Energy: Long-term rust prevention of bridge steel structures, high-voltage transmission towers, gas cabinets, and sewage treatment facilities. Other scenarios: Protection of steel components that are resistant to high and low temperatures and chemicals, such as metallurgical plants, heavy machinery, and vehicle chassis.
