ECCOBOND LUX OGR146TUV
Harmonization Code : 38159000 | Unspecified reaction initiators, accelerators, and catalytic preparations
Main features
- UV and Shadow-Area Thermal Cure
- Low-Refractive-Index Optical Bonding
- Extended 91-Day Working Window
Product Description
LOCTITE ECCOBOND LUX OGR146TUV is a one-part photocurable acrylate adhesive for optical devices, fiber-optic assemblies, and optoelectronic components. UV exposure provides the primary cure, and secondary thermal schedules of 1 hour at 100 deg C or 2 hours at 85 deg C address material in shadowed areas after light curing. The cured adhesive has a low refractive index across multiple optical wavelengths, including 1.464 at 589 nm and 1.454 at 1550 nm. A 91-day work life at 25 deg C supports extended process availability for controlled, high-throughput assembly.
Key features
- UV and Thermal Dual Cure: UV cure is supplemented by defined thermal schedules for adhesive in shadowed areas.
- Low Refractive Index: Cured refractive index ranges from 1.464 at 589 nm to 1.454 at 1550 nm.
- Extended Work Life: A 91-day work life at 25 deg C supports long process availability before cure.
Applications / Suitable for
- Optical devices
- Fiber-optic assembly
- Optoelectronic assembly
- High-throughput optical assembly
