This standard specifies the classification, requirements, test methods, inspection rules and marking, packaging and storage of epoxy graphene zinc powder primer products. This standard is applicable to multi-component coatings composed of epoxy resin and curing agent as the main film-forming substances, graphene powder materials, zinc powder (descaling zinc powder), solvents, etc. This coating is used for steel substrates Anti-rust. This standard applies to solvent-based epoxy graphene zinc powder primer products with a metallic zinc content in non-volatile matter greater than 20%.
