Technical Product Bulletin
PRODUCT DESCRIPTION
AA-BOND F123 is a low viscosity, two-component epoxy formulation that signals both proper mixing and curing when bonding fiber optic bundles, potting glass fibers, and/or terminating single or multi-channel fiber optic connectors.
AA-BOND F123 exhibits good wicking, and develops strong, tough, mechanically stable bonds to a wide variety of fiber optic and optical materials that includes most metals, ceramics, glass and many plastics.
AA-BOND F123 has good impact and thermal shock resistance, and yields excellent low stress, pot-and-polish connections which do not piston during cycle tests. It is also resistant to water and weathering, vapors and gases, most petroleum products, and an extended range of organic and inorganic environments. Shorter cures at higher temperatures. An additional post-cure of 30 minutes at 150°C is recommended when application temperatures higher than 150°C are anticipated.

GENERAL INFORMATION
For safe handling information on this product, consult the Safety Data Sheet, (SDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply AA-BOND F123 completely mixed adhesive to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
- Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.
- Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.
- Allow the product to cure according to the cure schedule.
AVAILABILITY
This epoxy can be supplied in many different packages.
