Application characteristics
At the end of the blue phase：r288 average particle size is close to the scattering of blue light in titanium dioxide theory the optimum particle diameter, small particle size of TiO2 is higher than that of large particle diameter is more effective, so it has more blue bottom and excellent whiteness.
Excellent dispersion：special inorganic surface treatment and organic surface treatment to reduce the contact between the TiO2 particles, so that R288 in the application process showed excellent dispersion. So good wettability, easy to grind.
Low oil：R288 low oil, titanium dioxide to maintain good processing performance in the application process in the plastic.
High weather resistance：R288 using zirconium coating treatment process to improve the weather resistance and heat resistance of titanium dioxide, and thus the chemical properties are very stable.
Good system compatibility：R288 special organic surface treatment, is very suitable for the non polar system and oily system, so in the application showed good system compatibility.
Packing：25 kg plastic woven bag for mixed bag or 500, 1000 kg of plastic.
Product storage：as 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. |
