Frequently Asked Questions (FAQ)

Q1: What is the curing speed of 3311-2M UV adhesive?

A: It cures within seconds upon exposure to UV light at 400 mJ/cm². Actual cure speed depends on light intensity, wavelength, and joint layer thickness.

Q2: Which substrates are compatible with this adhesive?

A: It is specially formulated for plastic-to-plastic substrates, including medical-grade plastics used in anesthesia masks, respiratory masks, and flexible tubing systems.

Q3: What are the performance advantages of Shore D 55 hardness?

A: A hardness of Shore D 55 offers an optimal balance of structural rigidity and flexibility. Combined with a 14 MPa tensile strength, it prevents joint failure under repeated flexing or pressure.

Q4: What are the storage requirements and shelf life?

A: The shelf life is 12 months when stored in unopened containers at 8–28°C in a light-shielded environment. Reseal tightly after each use.

Q5: Is this adhesive suitable for automated dispensing equipment?

A: Yes. Its low viscosity of 300 ± 100 mPa·s guarantees consistent flow rates and high precision in automated dispensing production lines.
