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.
