Optically Clear Adhesive (OCA) Tape
High Transparency
Non-yellowing
No Bubble
Low Haze
UV resistant
Minimal Shrinkage
Whtape Optically Clear Adhesive OCA tape is a high-performance adhesive designed for bonding transparent optical components such as lenses an touch screen. It features colorless transparency, ensuring a light transmittance rate of over 90%. With excellent bonding strength, it can be cured at room or moderate temperatures, offering stable adhesion without significant shrinkage during the curing process. This makes it an ideal solution for optical devices requiring precision and clarity. Its ability to maintain optical clarity while providing strong adhesion is crucial for applications in electronics, display panels, and other optical assemblies.
