Fiber Optic Center Inc. (FOC) has introduced AngstromBond AB9320, a two-part, low-stress blue epoxy that the company says will not cause fiber core cracking or pistoning. While designed for terminating multimode and multi-fiber connectors, it also works well with singlemode and other specialty connectors, FOC asserts. The heat-cured product has a 60- to 90-minute working time, which FOC points out is "signficantly longer" than the standard adhesives used for multimode and multi-fiber terminations.
The AngstromBond AB9320 is a low-viscosity system that can be cured as quickly as 10 minutes at 100 degrees C. FOC says it's low-outgassing properties enable the adhesive to pass NASA outgassing requirements. The glass transitiion temperature epoxy is designed to produce a very high bond strength to glass, ceramic, metals, and most plastics.
