Products NanoUse ™ ZR｜Nissan Chemical Corporation Inorganic Materials

Zirconia/titania sol have been developed using Nissan Chemical's proprietary manufacturing technology.
These are highly concentrated and stable metal oxide sols that can be used in a binder for optical applications,
titanium precision casting and various catalysts.

NanoUse^® ZR　▼: A water-dispersed zirconia sol with high
concentration and chlorine-free properties.
This is used as a binder for titanium precision
casting and various catalysts.

NanoUse^® OZ／OT　▼: Zirconia/titania sols dispersed in water/organic
solvents have been developed for optical applications.
These have high dispersibility and a high refractive
index and can be used as a refractive index modifiers and reflective materials.

Basic properties of NanoUse^®OT

Particle addition amount and film refractive index

$Particle addition amount and film refractive index$

Filler：OT-RB300M7-20
Binder：DPHA（hexafunctional acrylic resin）
Substrate：glass
Film thickness：1μm

The refractive index can be adjusted to any desired refractive index by changing the amount of particles added.

Light-resistance

After adding an organic dye (sunset yellow) to a light-resistant TiO₂particle dispersion, the dye-containing dispersion was irradiated with UV light and the absorbance of the dye-containing dispersion was measured.

（without TiO₂
particles）
OT-RA305
M7-20
Anatase
TiO₂
particles

During TiO₂particle UV irradiation, the dye decomposes due to the photoactivity of TiO₂. OT-RA305M7-20, in which photoactivity is suppressed, significantly reduces the decomposition of the dye.

Coating film properties

Filler：OT-RA305M7-20
Binder：DPHA（hexafunctional acrylic resin）
TiO₂ content：100phr
Substrate：sapphire glass
Film thickness：1μm

Refractive index	1.68
Haze	0%

Low Haze, high transparency coatings can be formed.
