Zirconia-dispersed UV curable resins
Tradename: LUXYDIR
Functional Products
Zirconia (Zr)-dispersed UV resins with high refractive index, transparency and low viscosity.
Due to its excellent dispersion stability, it can be used alone or as a compounding material.
Contributing to higher definition and power saving of displays.
LUXYDIR can be used for a wide variety of applications. Examples of applications are; optical films, light extraction layers, thin film encapsulation materials, optical adhesives, and adhesives.
Dispersion stability
Particle size distribution does not change even after heating and decompression treatment
Viscosity and liquid refractive index

Coating film properties after UV curing (example)
| Test Item | CH-S-2145 | CH-S-2093 | CH-S-2092 |
|---|---|---|---|
| ZrO2 amount | 36% | 54% | 61% |
| Viscosity（mPa・s） | 145 | 4,548 | 54,700*1 |
| Cured film refractive index*2（594 nm） | 1.660 | 1.700 | 1.716 |
| Haze*2（CIE standard illuminant D65） | 0.76 | 0.48 | 0.48 |
| Total light transmittance*2（CIE standard illuminant D65） | 87.5 | 87.1 | 86.3 |
| ｂvalue*2（CIE standard illuminant D65） | 1.4 | 1.1 | 1.9 |
| ｂvalue*2（after heat resistance test 100℃, 24h） | 1.6 | 1.0 | 1.4 |
*1 Measurement conditions: 10 rmp, 25℃. Due to its thixotropy, the viscocity varies depending on the measurement conditions.
*2 Measured value of coating film alone.
〇 Cured Film Preparation Conditions
・ LUXYDIR / Runtecure 1108 = 100 / 3.0 (wt%) ＊Diluted to 80% solids with MEK
・ Light source: Fusion (H-Bulb)
・ Irradiation dose: 400 mJ/cm2 (200 mJ/cm2 × 2 passes, nitrogen atmosphere)
・ Film thickness: 50 µm
The above data is an example. Please consult us about your requests for refractive index, liquid and film properties, etc.
*We also develop dispersions and solvent based prototypes that meet your requirements of the refractive index.
Transparency
Realize transparency in the cured coating film state.
