This standard specifies the technical requirements and test methods for chlorosulfonated polyethylene (PE) anti-corrosion coatings, including cloud iron, iron red undercoating and various color finish coating (two-component). It is suitable for anti-corrosion treatment of substrates such as steel structures and concrete. The standard covers the performance indicators of undercoating and finish coating, such as drying time, adhesion, resistance to saline water, etc., to ensure the anti-corrosion effect of Coatings in different environments. Detailed test methods and storage and transportation requirements are also provided to ensure the mass and use effect of Coatings.
