ÅngströmBond® AB9320 Blue Heat Cure Epoxy (2.5g Packet)

ÅngströmBond® AB9320 is a premium low-stress, heat-cure epoxy specifically formulated for terminating multimode and single-mode fiber optic connectors. Designed to provide reliable performance in demanding fiber optic applications, this dark blue adhesive offers exceptional bond strength, low shrinkage, and excellent resistance to environmental and chemical exposure.

Its extended working life provides significantly more assembly time than many conventional fiber optic epoxies, making it ideal for precision connector termination and high-volume production environments.

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

Features and Benefits

Designed for Fiber Optic Connector Termination

Optimized for multimode, single-mode, multi-fiber, MT, MTRJ, and PRIZM connector assemblies.

Low-Stress Formulation

Helps prevent fiber pistoning and fiber core cracking, ensuring long-term optical performance and connector reliability.

Excellent Adhesion

Bonds strongly to glass, ceramic, metal, and most engineering plastics.

Extended Working Time

Provides a longer pot life than many standard fiber optic epoxies, allowing additional time for connector assembly and alignment.

Easy Polishing

The dark blue color provides excellent visual contrast during polishing operations, helping technicians identify epoxy coverage and end-face quality.

High Thermal Stability

Features a high glass transition temperature for improved performance in elevated-temperature environments.

NASA Low-Outgassing Qualified

Meets NASA ASTM E595 outgassing requirements, making it suitable for aerospace, vacuum, and other sensitive applications.

Chemical and Environmental Resistance

Withstands exposure to a wide range of chemicals and harsh environmental conditions.
