ÅngströmBond® AB9123EP High Temperature Fiber Optic Epoxy, Heat Cure, 8 oz Kit
AB9123EP-8OZ

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

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

Supplied as an 8 oz kit, AB9123EP is well suited for production environments requiring larger quantities of high-performance epoxy for connector assembly and optical component manufacturing.
