ÅngströmBond® AB9110LV Clear Epoxy for PM and Plastic Optical Fiber (POF), Room Temperature & Heat Cure (2.5g Packet)

ÅngströmBond® AB9110LV is a low-viscosity, clear two-part epoxy designed for fiber optic, optical, electrical, and industrial bonding applications. Its low-stress formulation makes it particularly well-suited for polarization-maintaining (PM) fibers and plastic optical fiber (POF) assemblies, where minimizing fiber stress is critical to maintaining optical performance.

This versatile adhesive provides excellent wetting characteristics, strong adhesion to a wide range of materials, and reliable performance across extreme temperature environments. With room-temperature and heat-cure options, AB9110LV offers flexible processing for laboratory, production, and research applications.

Supplied in a convenient 2.5-gram packet for accurate mixing and reduced material waste.
