WHY ISK’s LD Series?
TiO2 Nanodispersions for Transparent High-RI Films
ISK’s LD Series materials are TiO2 nanoparticle dispersions for the development of transparent, high-refractive-index organic-inorganic films.
They are intended for formulation work where refractive index, low haze, resin compatibility and processability must be balanced. ICUSA can coordinate technical discussions based on your target refractive index, resin or coating system, film thickness, haze / transmittance requirements and evaluation process.
Application Needs
- Transparent high-refractive-index coatings requiring low haze and controlled optical properties.
- AR/VR waveguide and optical film development.
- Nanoimprint lithography (NIL) resin systems requiring inorganic nanoparticle dispersion and resin compatibility.
- Custom formulation discussions based on refractive-index target, resin system, solvent requirements, film thickness and processing conditions.
Use in High-Refractive-Index Coatings & Resins
- 1. Coating Apply resin containing TiO2 nanoparticles.
- 2. Imprinting Press a mold to form the target pattern.
- 3. UV Curing Cure the patterned resin under evaluation conditions.
- 4. Release Remove the mold and review optical film properties.
