Rutile titanium dioxide R - 666
Product Introduction
Rutile titanium dioxide R - 666 is a new - generation general - purpose (water - biased) rutile titanium dioxide developed by our company. By integrating the production quality control experience of rutile titanium dioxide via the sulfuric - acid method and innovative research in aspects such as inorganic coating, organic treatment, salt treatment, calcination control, hydrolysis and product application, and adopting hue and particle - size control, multi - element inorganic coating of zirconium, silicon, aluminum and phosphorus as well as new organic treatment technology, this product is suitable for the powder coating industry.

Application Characteristics
Blue undertone：The particle size of R - 666 is small and uniform. It can scatter blue light more effectively than larger particle sizes, thus having a bluer undertone and excellent whiteness.
High Weather Resistance：R - 666 has a high rutile content, a complete crystal lattice, and sufficient filler added. With an adequate amount of multi - element inorganic coating of zirconium, silicon, aluminum, and phosphorus as well as organic treatment, it can ensure high weather resistance.
Excellent dispersibility：The special inorganic and organic surface treatments reduce the contact between TiO₂ particles, enabling R - 666 to exhibit excellent dispersibility during application. As a result, it has good wettability and is easy to grind.
Low Oil Absorption：The low oil absorption of R - 666 enables the titanium dioxide to maintain good fluidity during the application in coatings and inks, which is conducive to cost - saving.
Low abrasion:R - 666 adopts special hydrolysis, salt treatment, calcination and surface treatment processes, which make the titanium dioxide particles soft and easy to grind, thus resulting in low abrasion.
Packaging:It is packed in 25-kilogram paper-plastic composite bags or 500-kilogram and 1,000-kilogram plastic woven bags.
Product Storage：As long as it is protected from moisture, it can be stored for a long time.
Protection:When handling TiO2, gloves and a protective shield should be worn. In case of skin contact, this compound poses no danger, but it is recommended to wash the skin after use.
