Product Details Description
Product Applications
- Solder joint protection for TWS earbuds and earphone PCBA
- Fixing of small electronic components in earphone assemblies
- Bonding of plastic and metal parts in earphone assemblies
- Reinforcement of precision electronic assemblies
- Speaker, microphone and battery component fixing
- Applications requiring low shrinkage and low dielectric constant
- High-throughput automated assembly with 3-5s LED curing
- Protection of fine solder joints against vibration and drop impact
Precautions
- Surfaces must be clean, dry and free of oil, dust or flux residues before bonding.
- Apply a suitable bead; avoid excess adhesive around contacts 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 substrates 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.
