Technical Specifications

FAQ

Q1: What is this adhesive mainly used for?
It is a UV + moisture dual-cure liquid optical clear adhesive (LOCA) designed for display bonding, such as bonding touch panels to cover glass or LCM.

Q2: Why is a dual-cure system needed?
The UV + moisture dual-cure system ensures the adhesive fully cures even in shadowed or edge areas that UV light cannot reach after display bonding, improving reliability.

Q3: What are its optical and weatherability properties?
It offers anti-yellowing performance, high transparency, good weatherability and low odor, and has passed a 100°C x 240 h boiling water test.

Q4: Is it safe for ITO circuits and skin contact?
Yes. It is non-corrosive to ITO and non-irritating to skin, making it suitable for display bonding and production handling.

Q5: What curing condition does it require?
It cures under UV light at 3000 mJ/cm² and continues moisture curing in shadowed areas, enabling efficient display bonding.

Q6: What is the shelf life and available packaging?
The shelf life is 12 months when stored at 8-28°C in the original sealed container, away from direct sunlight. Packaging options are 50g, 300g and 800g.

Ideal for high-cleanliness display bonding, delivering durable optical clarity, reliable shadow-area curing and long-term anti-yellowing weatherability.
