FAQ
Q1: How fast does the UV adhesive cure?
A: The adhesive cures within seconds under UV irradiation at 300 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 flexible plastic to plastic bonding, including medical grade plastics used in laryngeal masks, catheters and other disposable medical devices.
Q3: Why is the hardness lower than standard UV adhesives?
A: The low hardness (Shore D 40) combined with excellent elongation at break provides a flexible bond that withstands repeated bending and deformation, which is essential for laryngeal mask applications.
Q4: 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.
Q5: Is the adhesive suitable for automatic dispensing machines?
A: Yes. The viscosity grade of 400±100 mPa·s ensures stable flow and precise dispensing, making it fully compatible with automatic dispensing equipment.
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.
