FAQ

Q1: How fast does the UV adhesive cure?

A: The adhesive cures within seconds under UV irradiation at 700 mJ/cm². Actual curing speed depends on the UV light source, wavelength and adhesive layer thickness.

Q2: What materials can this UV adhesive bond?

A: It is specially designed for bonding plastics to metals, including stainless steel, aluminum, PC, ABS and other medical-grade plastics, making it ideal for injection needle hub fixation.

Q3: 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 use.

Q4: Does the adhesive support automatic dispensing on production lines?

A: Yes. The low viscosity grades (550±100 mPa·s and 1500±300 mPa·s) enable precise automatic dispensing and capillary flow into tight joint gaps, suitable for high-speed assembly lines.

Q5: Is a fluorescent trace version available?

A: Yes. A fluorescent trace version is available, which allows easy online quality inspection under UV light after bonding.

Q6: What packaging options are available?

A: Standard packaging is 1 kg. Custom packaging such as syringes, bottles and other sizes can be provided upon request for OEM orders.
