★Particle size
The hydrolysis process well designed by “Fangyuan Titanium Dioxide” enables FR-767 rutile grade general purpose titanium dioxide to be of small particle size, and have whiter tint, blue undertone and higher hiding power.
★Surface treatment
The optical performance of FR-767 rutile grade general purpose titanium dioxide 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 FR-767 rutile grade general purpose titanium dioxide to have better hiding power, higher luster and excellent weather resistance. The dispersibility of FR-767 rutile grade general purpose titanium dioxide has been greatly improved when the surface of FR-767 is coated with organic agent.
★Particle size distribution
The particle size distribution of FR-767 rutile grade general purpose titanium dioxide is more concentrated with adoption of strict hydrolysis calcinations process, giving FR-767 rutile grade general purpose titanium dioxide a higher luster, better dispersibility, excellent hiding power and color strength.
★Applicable scope
Indoor and outdoor coatings, powder coatings and color master-batch, plastics systems etc.
★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, FR-767 rutile grade general purpose titanium dioxide has blue undertone tint and excellent whiteness Content.
2.High weather resistance: FR-767 rutile grade general purpose titanium dioxide 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 FR-767 rutile grade general purpose titanium dioxide 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.
