Technical Specifications

FAQ

Q1: What is the 3750 adhesive mainly used for?
It is a UV + moisture dual-cure liquid optical clear adhesive designed for full lamination in the electronic touch panel industry, such as laminating 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 lamination, improving reliability.

Q3: What are its optical and weatherability properties?
It offers ultra-high cleanliness, excellent yellowing resistance, 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 causes no corrosion to ITO and is non-irritating to skin, making it suitable for touch panel full lamination 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 full lamination curing.

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 full lamination in electronic touch panel manufacturing, delivering durable optical clarity, reliable shadow-area curing and long-term weatherability.
