Frequently Asked Questions (FAQ)

Q1: How fast does the 3791 UV adhesive cure?

A: The adhesive cures rapidly under UV irradiation with a total energy requirement of 1000 mJ/cm². Actual curing speed depends on the UV lamp intensity, wavelength, and coating layer thickness.

Q2: What materials can this 3791 UV adhesive bond?

A: It is specially designed for bonding glass to glass and glass to metal substrates, including ITO glass, LCD panel substrates, stainless steel, and aluminum frames.

Q3: Is 3791 UV adhesive suitable for high-humidity environments?

A: Yes. It features outstanding damp-heat resistance and a high Tg (75°C), preventing degradation, yellowing, or delamination in warm and humid operating conditions.

Q4: What are the main benefits of its high viscosity (20,000 mPa·s)?

A: The high viscosity formulation prevents sagging and overflowing during application, allowing precise dispensing around LCD panel edges and tight seal gaps.

Q5: What are the storage requirements and shelf life?

A: Shelf life is 12 months when stored at 8–28°C in a cool, dry place away from direct sunlight. Keep the container tightly sealed after each use.

Q6: What packaging options are available?

A: Standard packaging is 1 kg. Custom packaging (such as syringes or smaller black bottles) can be provided upon request for automated production line compatibility.
