ÅngströmBond® AB9123EP High Temperature Fiber Optic Epoxy, Heat Cure, 2.5g Packet
AB9123EP-2.5G

The ÅngströmBond® AB9123EP is a high-temperature, heat-curing, two-part epoxy adhesive specifically formulated for fiber optic connector termination and precision optical assembly applications. Featuring an extended working life of 7–8 hours, this low-viscosity epoxy offers excellent handling characteristics while delivering exceptional bond strength to glass, metals, ceramics, and many engineering plastics.

Designed using proven fiber optic connector adhesive chemistry, AB9123EP combines rapid heat-curing performance with excellent thermal stability and environmental durability. Its high glass transition temperature (Tg) helps satisfy demanding connector pistoning requirements, while its superior resistance to temperature cycling and high-humidity environments supports long-term reliability in telecommunications, datacom, aerospace, defense, and industrial applications.

Supplied in a convenient 2.5-gram packet, AB9123EP is ideal for fiber optic connector assembly, field termination, repairs, and low-volume production environments requiring a high-performance epoxy with extended pot life.
