This standard defines the technical requirements and test methods for epoxy asphalt anti-corrosion coatings (aliquot), which are suitable for two-component anti-corrosion coatings with epoxy resin and coal char asphalt as binders. The standard includes formulation requirements, performance tests and Encasement marks for coatings, especially for corrosion protection of underwater and underground steel structures. The performance indicators include drying time, bending resistance, impact resistance, etc., to ensure the long-term Stability and durability of Coatings in harsh environments.
