Environmentally friendly, non-toxic, free of heavy metal, extremely easily dispersible, and non-combustible. Resistance
to salt water and spray salt of prepared paint film ranks first among similar products.
The anti-corrosive pigment industry is a sector that produces and supplies pigments that can be used to protect metal
surfaces from corrosion. These pigments are typically added to coatings, paints, and other protective coatings to enhance
their corrosion resistance properties.
The main function of anti-corrosive pigments is to create a barrier between the metal surface and the surrounding environment, preventing the metal from coming into contact with moisture, oxygen, and other corrosive agents. This helps to prolong the
lifespan of metal structures and equipment, reducing maintenance and replacement costs.
Anti-corrosive pigments can be classified into two main categories: inhibitive pigments and barrier pigments.
1. Inhibitive pigments: These pigments work by releasing corrosion inhibitors that form a protective layer on the metal surface.
The inhibitors react with the metal and create a passivation layer, preventing further corrosion.
2. Barrier pigments: These pigments create a physical barrier on the metal surface, preventing corrosive agents from coming into
contact with the metal. They can be in the form of flakes, platelets, or lamellar structures that act as a shield against moisture
and other corrosive substances.

Usage: Dispersed and directly blend with base, auxiliary materials, additives and solvents.
Rust-proof Mechanism:
Chemical anti-rust: Modified molybdate and phosphate undergo a complexation reaction with painted surface,
forming insoluble passive film and inhibiting corrosion to metal base such as steels from the environment.
Main Applications:
The product is widely used. Its performance surpasses traditional anti-rust pigments such as zinc molybdate,
aluminum tripolyphosphate, zinc phosphate and calcium hydrophosphate, and is widely applied in such fields as
rolled steels, mechanical and electrical products, steel structure, ships and oil pipelines.
Suggested dosage:
It is suggested to use between 5%~10%.
