ÅngströmBond® AB9110LVBL Blue Epoxy for PM Fiber and Plastic Optical Fiber (POF), Room Temperature & Heat Cure (2.5g Packet)

ÅngströmBond® AB9110LVBL is a low-viscosity, dark blue, two-part epoxy designed for fiber optic, optical, electrical, and industrial bonding applications. Engineered for low-stress bonding, it is particularly well-suited for polarization-maintaining (PM) fibers and plastic optical fiber (POF) assemblies where preserving optical performance is critical.

This versatile epoxy offers excellent wetting characteristics, strong adhesion to a wide variety of substrates, and reliable performance across extreme temperature environments. Its dark blue color improves visibility during assembly and polishing operations, while room-temperature and heat-cure options provide processing flexibility for both laboratory and production environments.

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