Heavy Metal-Free Silica Anti corrosion Pigments
As the new generation anti-corrosion pigment with efficient, non-toxic, no heavy metal,
Ion-exchanged modified silica is the smart choice to respond to the high requirements of environmental protection.
- A variety of modified products: meet different application requirements
- Best performance: Neutral salt spray test, MEK resistance, acid and alkali resistance
- Better processing performance: No grinding required, good dispersibility, suitable for thin film system
Silica Anti-corrosion Pigments
- Main raw material: Amorphous silica
- Other function materials: Calcium Oxide etc.
- Characteristic: Ion-exchange, calcium oxide-modified silica, non-toxic and free heavy metal.
- Appearance: white, non-crystalline powder
- R&D background: to replace traditional anti-corrosion pigments, such as zinc phosphate, strontium chromate, etc., to meet with increasing environmental problems and regulatory restrictions
- Application: general industrial paints, coils, automotive coatings, home appliance panels, etc.
Features & Protection Mechanism
Features: Environment protection, no heavy metals, low oil absorption, easy to disperse, not easy to foam, long-lasting protection.
Chemical Protection:
Resist acid corrosion, Anti-corrosion pigments modified with calcium ions will react with water molecules and hydrogen ions seep into the coating film. It will generate hydroxide ions and release calcium ions, to keep the pH value-neutral or alkaline, avoid the metals for acidic hydrogen evolution corrosion, and reduce the coating films’ bulge phenomenon.
Physical Protection:
When metals have corrosion, the anode generates iron or ferrous ions, and the cathode generates hydroxide ions. Hydroxide ion will react with silica and release silicate ion, the hydroxide will react with iron ion or calcium ion to generate silicate and cover the surface of the metal to bring an inert protective layer, thereby, the electrochemical reaction of the metal is further prevented, and the corrosion is prevented from continuing to occur effectively.

The Ultimate FAQ Guide
Anti-corrosion pigment appearance is a white powder, the main ingredient is Ion-exchanged amorphous silica, it’s non-toxic, has no heavy metals, and accords with present and future environmental regulations. The anti-corrosion pigment with ion-exchanged processing has a very high value of the specific surface area, high reactivity, calcium ions can exchange with hydrogen ions entering the coating film, release calcium ions, and maintain the coating film to be weakly alkaline, and can weakly release silicate ions that have the effect of inhibiting corrosion. Silicate ions can combine with metal ions to make a protective layer to protect the steel substrate, reduce corrosion and extend the service life. It is used in the preparation of anti-corrosion coatings, and it is a new variety of non-toxic anti-rust pigments developed in recent years.
