High-performance Coating Material PHOTOCLEAR™
PHOTOCLEAR™ is a coating material excelling in heat resistance and chemical resistance while having high transparency.
It is used widely as an insulation layer/protective film material for touch panels, and flattening film material for TFT array.
Using our proprietary design siloxane resin allows for a combination of high heat resistance, high light resistance, high transparency, and high hardness.
Through combining polymer technology and nanoparticle dispersion technology, we are developing refractive index adjustment materials and glass reinforcement materials, etc.
Touch Panel Application Examples
