1. Characteristics of TTO series

• TTO series are ultra-fine TiO₂ products whose particle size is below 100nm.

• TTO series can achieve excellent transparency and UV-shielding capability.   (Click here for transparency of TTO series.)

• When applying for metallic paints, viewing color is varied due to the light scattering ability which is characteristics of ultra-fine TTO.  (Click here for flip-flop effects.)

• Physically and chemically stable due to the rutile crystal.

• Various grades are available depending on the particle size, manufacturing methods and surface treatment.

Major applications

      sunscreen cosmetics, automotive paint, toner additives, etc.
