Tra-Con Color Keyed, High Temperature Epoxy Adhesive

Tra-Con Part No.: BAF253

  • $ 13.69 or

BAF253 is a low viscosity, high temperature, two-part epoxy formulation that changes color during the curing process to indicate cure status.


  • Packaged in a 2 gram rigid plastic tube separated by a leak-proof clamp (BIPAX) which eliminates mix ratio errors
  • Excellent wicking, and develops strong, tough mechanically stable bonds
  • Good impact and thermal shock resistance
  • Low stress
  • Resistant to water and weathering, vapors and gases, most petroleum products, and an extended range of organic and inorganic environments
  • Can be used on a wide variety of fiber optic and optical materials that includes most metals, ceramics, glass and many plastics
  • Yields excellent pot and polish fiber optic connections
  • This package will prepare approximately 25~30 fiber optic connectors

Mixing Instruction:

  • Remove the clamp and mix right inside the BIPAX.
