Transparent Material PHOTOCLEAR™

Technological Elements

PHOTOCLEAR™
PHOTOCLEAR™ is a coating material exceling 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 arrays. Using our uniquely designed siloxane resin allows for a combination of high heat resistance, high light resistance, high transparency, and high hardness. By combining polymer technology with nanoparticle dispersion technology, the refractive index can be adjusted and the glass strength can be improved.

Features

1. Our proprietary resist design technology produces superior pattern processability and high reliability.
2. Using our uniquely designed siloxane resin allows for a combination of heat resistance and transparency.
3. Proven performance in a wide range of applications, typically in smartphones, automobiles, and computers.

High Heat Resistance → Low Outgas
High Light Resistance → Superior Light Stability
High Transparency → Superior Optical Characteristics
High Fluidity → Superior Flattening Ability
High Hardness → Excellent Protective Film Properties
Low Elasticity → Excellent Adhesion
