Specifications
Features & Advantages
✅High bonding strength
✅High viscosity
✅Anti-aging & durable
✅Easy to operate
✅Eco-friendly grade
Application: Bonding LED lens to aluminum substrate; bonding & potting sealing for plastics including PMMA, PC, PVC, and metals like aluminum & copper.
Operation Steps
- Clean the bonding surface thoroughly, then apply glue slowly; avoid air bubbles.
- Cure with UV lamp at 10-30cm distance for around 15 seconds. (Exact time depends on your actual UV lamp).
- Increase UV intensity or curing time for thicker glue layers.
- Seal unused adhesive and store at room temperature away from light.
Important Note: The cured resin layer thickness per application must be less than 1 mm.
Recommended UV Curing Light
- 400W (11mW/cm²) UV lamp
- 20W UV flashlight, wavelength ≤395nm
- Other UV lamps that meet curing requirements
