★Particle size
The hydrolysis process well designed by “Fangyuan Titanium Dioxide” enables rutile grade general purpose tio2 to be of small particle size, and have whiter tint, blue undertone and higher hiding power.
★Surface treatment
The optical performance of rutile grade general purpose tio2 can achieve the greatest effect by means of advanced inorganic and organic surface treatment with zirconium and aluminum. Zirconium compound has been utilized for surface treatment which enables rutile grade general purpose tio2 to have better hiding power, higher luster and excellent weather resistance. The dispersibility of rutile grade general purpose tio2 has been greatly improved when the surface of FR-767 is coated with organic agent.
★Particle size distribution
The particle size distribution is more concentrated with adoption of strict hydrolysis calcinations process, giving rutile grade general purpose tio2 a higher luster, better dispersibility, excellent hiding power and color strength.

★Application characteristics
1.Blue undertone tint: The particle size is small and homogeneous, which can scatter blue light more effectively than big particle size, therefore, rutile grade general purpose has blue undertone tint and excellent whiteness Content.
2.High weather resistance: Rutile grade general purpose is of lattice perfection and it adopts advanced inorganic and organic surface treatment with zirconium and aluminum, thereby higher weather resistance can be assured.
3.Excellent dispersibility: Special inorganic and organic surface treatment lower coalescence between TiO2 particles, which causes rutile grade general purpose to show excellent dispersibility in the application systems.
4.Lower oil absorption: The low oil absorption makes Titanium Dioxide own good wettability and easily-dispersed in application systems, which is beneficial to cost.
