Application characteristics 
Blue bottom phaseR219 small and uniform size, more effective than the large particle size of the blue light, so with a more blue background and excellent whiteness.
High weather resistance:R219 has a higher content of rutile, complete lattice, fillers increase the amount of foot, take adequate amounts of zirconium aluminum silicon phosphorus diverse inorganic coated and organic processing, thus ensuring a high weather resistance. 
Excellent dispersionspecial inorganic surface treatment and organic surface treatment to reduce the contact between the TiO2 particles, so that R219 in the application process showed excellent dispersion. So good wettability, easy to grind.
Low oil absorptionR219 low oil, the titanium dioxide to maintain good liquidity in the process of application of water-based paints, inks, to saving the cost.
Low wear:R219 using a special hydrolysis, salt treatment, calcination and surface treatment process, so that the titanium dioxide particles are soft, easy to grind, and thus wear low. 
Packing:25 kg plastic woven bag for mixed bag or 500, 1000 kg of plastic.
Product storageas long as avoid damp, can be long-term storage.
Safety protection:in the treatment of TiO2, should wear gloves and protective cover. If skin contact occurs, the compound will not be dangerous, but it is recommended to clean the skin after use.
