1. Paint industry
Silicon dioxide pigments are widely used in the coatings industry, mainly for:
Extinguishing agent: Nano silica can absorb light, reduce the glossiness of coating surfaces, and is widely used in fields such as wood coatings and architectural coatings.
Rust proof pigment: Silicon dioxide ion exchange type rust proof pigment inhibits corrosion of metal surfaces through ion exchange, and is widely used in rust proof coatings in industries, transportation, and construction.
Retention aids and adsorbents: used in paper coating and inkjet printing fields to improve pigment adhesion and color saturation.


2. Rubber and tire industry
Silicon dioxide is an important filler and reinforcing agent in the rubber industry, mainly used for:
Green tires: Highly dispersed silica is used to replace traditional carbon black, reduce tire rolling resistance and fuel consumption, and improve wet skid resistance.
Rubber products: In rubber products such as shoes and silicone rubber, silicon dioxide can improve the hardness, wear resistance, and thermal stability of the product.


3. Toothpaste and Oral Care Industry
Silicon dioxide is commonly used as a grinding and thickening agent in toothpaste, with good cleaning and polishing properties, and no damage to teeth.


4. Feed and pharmaceutical industries
In the fields of feed and medicine, silica is commonly used as a carrier and filler, such as vitamin E carrier, drug carrier, etc.


5. Electronic and Optical Communication Industry
Silicon dioxide is used in the fields of electronics and optical communication to manufacture high-performance insulation materials, catalyst carriers, and optical materials.


6. Ink and Adhesive Industry
Silicon dioxide pigments are mainly used as reinforcing and thickening agents in inks and adhesives, which can improve rheological properties and dispersibility.


7. Other applications
Silicon dioxide pigments are also widely used in:
Cosmetics: As an additive, provide good touch and stability.
Plastic film: As an opening agent, it prevents the film from sticking.
Power equipment and petroleum and petrochemical industries: used for anti-corrosion coatings and insulation materials.

summary
Silicon dioxide pigments have been widely used in industries such as coatings, rubber, toothpaste, feed, pharmaceuticals, electronics, and inks due to their excellent optical, mechanical, and chemical properties. With the increasing demand for environmental protection and high-performance materials, the market prospects for silica pigments are broad.
