Silicone OCA for Vehicle Displays

Excellent Long-Term Reliability and Haptic Characteristics

This silicone type OCA offers long term reliability and optical stability, with minimal yellowing even under UV light or in high temperature environments. It also offers outstanding haptic characteristics in displays incorporating haptic technologies (tactile sensor technologies), an area marked by advances in recent years.
