How to Choose High-Quality Titanium Dioxide?

How to Choose High-Quality Titanium Dioxide?

In the global industrial field, titanium dioxide is known as the "king of white" - from durable coatings on building exteriors, anti-ultraviolet protection for automotive plastic parts, to the delicate color of lipstick, titanium dioxide is indispensable. However, the quality of titanium dioxide on the market varies greatly, and inferior products may cause paint peeling and plastic yellowing.

As a titanium dioxide supplier with 20 years of R&D experience, Dawn Group will reveal the 5 major scientific indicators and 3 pitfall avoidance principles for selecting high-quality titanium dioxide through this guide, helping you optimize production costs and improve the competitiveness of end products.

Understanding Titanium Dioxide Fundamentals

Titanium dioxide is a white inorganic compound (chemical formula is TiO₂) with high refractive index and strong hiding power. Its two major crystal structures determine the application direction.
 
Rutile titanium dioxide: It has excellent weather resistance and is suitable for outdoor coatings and automotive paints.
 
Anatase titanium dioxide: It has higher whiteness and is often used in papermaking and cosmetics.
 

5 Critical Factors for Selecting Premium Titanium Dioxide

Purity & Chemical Composition

Ordinary industrial-grade titanium dioxide (purity 98%-99%) may contain impurities such as Fe₂O₃ and SiO₂, which may affect the stability of the finished product.

Crystal Structure Selection

Outdoor coatings: Rutile titanium dioxide (UV-resistant) is preferred.
Indoor plastic products: Anatase titanium dioxide is more cost-effective.

Particle Size Distribution

The more uniform the particle size distribution of titanium dioxide, the stronger its hiding power and dispersibility.

Surface Treatment Technology

Silicon/aluminum coating treatment can enhance the weather resistance and resin compatibility of titanium dioxide.

Supplier Certifications & Testing

Choose suppliers certified by ISO 9001, REACH, and FDA.

 Common Mistakes to Avoid When Choosing Titanium Dioxide

  • Focus only on price: Low-priced products may lead to increased rework costs later.
  • Ignore application scenarios: High-temperature environments require special heat-resistant models.
  • Ignore technical services: Dawn provides 24-hour technical consultation to help customers optimize formulas.
