ÅngströmBond® AB9123 High Temperature Fiber Optic Epoxy, Heat Cure, 8 oz Kit
AB9123-8OZ

The ÅngströmBond® AB9123 is a high-performance, heat-curing, two-part epoxy adhesive designed for fiber optic connector termination and precision optical assembly applications. This low-viscosity epoxy system provides exceptional bond strength to glass, metals, ceramics, and many engineering plastics while offering fast curing characteristics for efficient production environments.

Engineered using industry-proven connector termination chemistry, AB9123 delivers excellent thermal stability, outstanding environmental resistance, and a high glass transition temperature (Tg) that helps meet demanding connector pistoning requirements. Its superior resistance to temperature cycling and high-humidity conditions makes it well suited for telecommunications, datacom, aerospace, defense, and industrial applications.

Supplied as an 8 oz kit, AB9123 is ideal for manufacturing operations requiring larger quantities of reliable, high-temperature epoxy for fiber optic connector assembly and optical component bonding.
