Type S has the average primary particle size of 60nm (0.06 μm). It is an excellent inorganic pigment characterized by low L value of around 11 with bluish black color, and its specific surface area is over 20m2/g. Type M has the primary particle size of 80 – 100nm.
Titan Black belongs to titanium oxide type pigment, a new material showing black color. It’s unique properties deliver a variety of functions. We developed Titan Black by controlling oxygen content starting from titanium white pigment. Titan Black is the pigment having small particle diameter, high hiding power, nonmagnetic properties, and high dispersively in water and inorganic solvent. We provide two types of pigment, typeM characterized by conductibility (electric charge adjusting etc.) and type S characterized by superior hiding power.
High Light-Shielding (Type M-C) / High Insulation
Titan Black is the only black pigment having the features of both high light-shielding and high insulation features which are required to the black matrix used in LCD color filters and has been highly evaluated from LCD makers. We provide Titan Black not only in the form of powder but of dispersion in the liquid (water/organics).

High Optical Transmittance in Low Wavelength
Titan Black, even though black pigment, has very unique attribute, that is, it transmits light in low wavelength of visible light. This serves as high advantage in the production of BM which employs hardening reaction by ultraviolet exposure. High UV transmittance of Titan Black ensures the acquisitions of the wide process margin in patterning process and also high resolution resulting in finer line pattern.
Titan Black is very safe pigment comprising from titanium oxide and small portion of nitrogen. (Type M and Type S) Titan Black is registered as cosmetics materials and put into actual use. (Cosmetics Ingredients standard: Black titanium-oxide)
Titan Black is stable up to 300°C in the air, and it is oxidized over 300°C, returning to titanium dioxide. This is different from carbon black which emits harmful carbon monoxide when heated in the air.
Conductivity (Type M)
When Titan Black is used as conductive filler, it is possible to control smoothly the electric resistance without causing sudden change of conductivity as seen in carbon black.
Titan Black is nonmagnetic which conducts to long-term stability of coated layer and excellent dispersion in the paint.
