Product Details Description
Product Applications
- Acrylic and glass LED lens bonding and fixing
- LED backlight lens positioning in TVs and displays
- Diffuse reflection light bars: acrylic and PC lenses on LED strip modules
- Optical lens and precision optical component bonding
- Plastics-to-metal structural bonding
- Injection needle hub fixation
- Precision electronic and optical sub-assembly sealing
- Side-lit lens arrays and specialized LED fixture modules
Precautions
- Surfaces must be clean, dry and free of oil, dust or mold release agents before applying.
- High viscosity keeps the adhesive in place; dispense precisely to avoid flowing into unintended optical zones.
- UV curing requires light to reach the adhesive; opaque or UV-blocking materials may not fully cure.
- 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 keep out of reach of children.
- Bond performance may vary with substrate, gap and UV intensity; please run a bonding test before mass production.
FAQ
Q1: How does this UV light curing silicone glue cure?
It cures under UV irradiation with a recommended cumulative UV dose of 1200 mJ/cm². Actual curing time depends on lamp power, UV intensity and layer thickness.
Q2: What substrates can it bond?
It offers strong adhesion to acrylic (PMMA) and glass, and also bonds PC (polycarbonate), other optical plastics and metals.
Q3: Is the cured bond optically clear?
Yes. It cures into a high clarity, transparent bond line with high light transmission, so it will not affect the optical performance of LED lenses.
Q4: Why is high viscosity important for LED lens bonding?
The high viscosity (40,000 ± 10,000 mPa·s) keeps the adhesive precisely where dispensed without slumping or flowing into unintended optical zones before curing.
Q5: What is the packaging and minimum order quantity?
Standard packaging is a 1 kg bottle, and the minimum order quantity is 10 pieces. Custom syringe packaging is available for automated lines.
Q6: How should it be stored and what is its shelf life?
Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight. Unopened shelf life is approximately 12 months.
