OCA Optical Adhesive

OCA optical adhesive is mainly composed of acrylate pressure sensitive adhesive and is made of a composite release film. It has excellent optical properties/acid free, good functional sheet material compatibility (ITO, AgNW, etc.), excellent reliability, and good differential absorption.

1. LCD module and TP are fully bonded.
2.TSP bonding (G/F/F, G/F, P/F, etc.), explosion-proof film bonding, optical compensation film, polarizer bonding.
