Product Details Description

Product Applications

• Micro speaker and headphone diaphragm bonding and fixation
• Voice coil and diaphragm bonding in acoustic modules
• Speaker and receiver assembly fixing
• Bonding of metal and plastic acoustic components
• Precision fixing in miniature acoustic modules
• Fixing of fragile diaphragms that require high elongation
• Applications requiring low stress and low shrinkage
• High-throughput automated assembly with 3-5s LED curing

Precautions

• Surfaces must be clean, dry and free of oil, dust or release agents before bonding.
• Apply a suitable bead; avoid excess adhesive around diaphragm edges and acoustic openings.
• UV / LED curing requires light to reach the adhesive; shadowed areas may need additional passes.
• Confirm adhesion and cure depth on the actual acoustic components before mass production.
• 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 UV sources, and keep out of reach of children.

FAQ

Q1: What is this low stress high elongation UV adhesive mainly used for?

It is a UV curing adhesive used for micro speaker and headphone diaphragm fixation, as well as voice coil and diaphragm bonding in acoustic modules.

Q2: How fast does it cure?

It cures rapidly under LED or UV light in about 3-5 seconds, supporting fast automated acoustic module assembly.

Q3: What adhesion and stress performance does it offer?

It provides high adhesion and high tensile strength with low shrinkage and low stress, and its high elongation of 200% protects delicate diaphragms from cracking.

Q4: Why is red visibility useful?

The transparent red color gives high visibility, making it easy to inspect the dispensed adhesive and confirm correct placement during assembly.

Q5: Is it easy to dispense?

Yes. It has high thixotropy, so it dispenses cleanly and maintains its shape without running or sagging.

Q6: What are the storage conditions and packaging?

Store sealed at 8-28°C in the original container. Shelf life is 12 months. Available in 50g and 1kg packaging.
