ThreeBond 1630 is a UV-curing sheet adhesive in film form (27–33 µm thick), designed for face-bonding of transparent parts requiring excellent light resistance and optical clarity. Manufactured by ThreeBond Co., Ltd., it is transferred and pre-bonded by heat and pressure, then cured by UV irradiation to become transparent, flexible, and highly light-resistant — making it suitable for optical displays and light-exposed assemblies.
Features & Benefits
- Superior uniform film thickness (27–33 µm) for consistent optical bond line across large areas
- Excellent transparency and light resistance after UV cure — no yellowing over time
- Flexible after cure (Shore A35, 1.9×10⁶ Pa) — absorbs stress and accommodates substrate differences
- 5.1 MPa tensile shear on Glass/Glass and 4.0 MPa on Acrylic/Glass after standard cure
- Sheet format ensures uniform adhesive layer — no air bubbles or thickness variation
- Compatible with vacuum lamination process for bubble-free large-area optical bonding
Typical Applications
- Face-bonding of display panels, touch screens, and transparent optical assemblies
- Bonding of cover glass to LCD/OLED modules in consumer electronics
- Laminating of transparent protective films and light-resistant optical parts
- Display assemblies requiring long-term UV and light stability
