How to choose the type and indicators of titanium dioxide powder

Performance balance principle:

The higher the whiteness, the better: excessively high whiteness may lead to insufficient coverage (such as in dark substrate coatings), and a comprehensive evaluation of dispersibility and weather resistance is needed.

Titanium dioxide content ≠ performance: Surface coating (such as aluminum oxide or silicon oxide treatment) can improve dispersibility and reduce the amount of addition (the amount can be reduced by 15-20% under the same effect).

Cost control logic:

Priority should be given to choosing rutile type for outdoor scenes: although the unit price is high, the service life is 5-10 times that of rutile type, and the long-term comprehensive cost is lower.

Avoid high color fading in the color mixing system: Excessive color fading can neutralize colored pigments and increase the cost of color mixing (such as adding an additional 20% color paste for red paint).

Environmental Protection and Policy Trends:

Chlorination method is the mainstream of the future: China's 14th Five Year Plan promotes the localization of high-end titanium dioxide, and the production capacity of chlorination method is expected to reach 50% by 2025 (currently about 30%).

Driven by emerging markets: New energy vehicles (with a single vehicle titanium dioxide consumption of 5-8kg) and 5G communication (with MLCC demand increasing by 15% annually) have become new growth engines, and it is expected that the global titanium dioxide market size will exceed 30 billion US dollars by 2025.
