MP's water-based anticorrosive coating for steel structures is a specialized anticorrosive film formulated primarily from hydroxyl acrylic and polyurethane resins, combined with water-based rust-inhibitive pigments, extender pigments, and additives. During film formation, this coating forms a highly dense interpenetrating network structure with the surface of steel and concrete substrates, ensuring that the molecules in the MP anticorrosive coating are orderly and tightly arranged.
