Product Details Description
Product Applications
- TP (touch panel) lamination and optical bonding
- ITO coating bonding (non-corrosive to ITO circuits)
- Optical clear lamination of display modules
- Cover glass and touch sensor bonding
- Capacitive touch screen assembly
- Optical bonding of transparent components
- Weatherproof optical sealing for electronic displays
- Anti-glare and hardened film lamination
Precautions
- Perform lamination in a clean, dust-free environment; surfaces must be clean, dry and free of oil or particles.
- Apply a thin uniform layer; allow adequate deaeration to prevent air bubbles in the optical bond layer.
- UV curing requires light to reach the adhesive; UV-blocking or opaque areas may not fully cure.
- Apply in a well-ventilated area. Avoid contact with skin and eyes; wear protective gloves and safety goggles.
- In case of skin or eye contact, rinse immediately with plenty of clean water and seek medical advice if irritation persists.
- Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight, and keep out of reach of children.
- Optical performance may vary with substrate, layer thickness and UV intensity; please run a lamination test before mass production.
FAQ
Q1: How does this LOCA glue cure?
It is a UV-curable liquid optical clear adhesive. It cures under UV irradiation with a recommended cumulative UV dose of 3000 mJ/cm²; curing time depends on UV intensity and layer thickness.
Q2: Is it really non-corrosive to ITO coatings?
Yes. The formulation is non-corrosive to ITO circuits and non-irritating to skin, making it safe for touch panel and ITO coating lamination.
Q3: What about odor and purity?
It offers ultra-high cleanliness with low odor, ideal for optical-grade lamination where a clean, comfortable production environment is required.
Q4: Is it weatherproof and yellowing resistant?
Yes. It has excellent yellowing resistance and weatherability, and passes the 100°C x 240 h boiling water test for outstanding damp-heat durability.
Q5: What is the packaging and minimum order quantity?
Standard packaging is 50g / 300g / 800g bottles, and the minimum order quantity is 10 pieces. Custom packaging is available on request.
Q6: How should it be stored and what is its shelf life?
Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight. Unopened shelf life is approximately 12 months.
