ÅngströmBond® AB9113SC Fiber Optic Epoxy, Room Temperature & Heat Cure (2.5g Packet)

ÅngströmBond® AB9113SC is a low-viscosity, two-part epoxy specifically formulated for fiber optic connector termination, optical component assembly, potting, and sealing applications. Based on one of the industry's most widely used connector epoxy chemistries, it provides excellent adhesion to glass, metal, ceramic, and plastic substrates while maintaining low stress on optical fibers.

This 100% solids epoxy can be cured at room temperature or accelerated with heat, offering flexible processing options for both laboratory and production environments. Its low viscosity allows easy ferrule filling and component encapsulation, making it an excellent choice for fiber optic assembly and precision bonding applications.

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