About Opti-tec 5053-F-B High Temperature Fast Cure Epoxy Adhesive for Fibre Optic Terminating

Opti-tec 5053-F-B is a two-component, low viscosity, heat curing epoxy designed for high-temperature applications. It is especially well suited to fibre optic terminating, where optical fibres are “pot and polished” into connectors or ferrules.

Opti-tec 5053-F-B is an improved and fast cure version of Opti-tec 5053.

 

Fibre Optic Termination

Features & Benefits

  • High surface energy and low viscosity allows it to readily wet and wick between optical fibres. It develops strong adhesion to most materials used in fibre optics and optics, including metals, ceramics, glass and most plastics.
  • High glass transition temperature results in excellent high temperature performance and creep resistance
  • Resists moisture, vapours and most chemicals. It features low outgassing and low vapour pressure, making it an ideal sealing material for electronic and optical applications.
  • Colour change upon cure, going from clear to deep translucent red.
  • Specially formulated to have very low skin sensitivity
  • Long pot life and good handling characteristics
  • Used for Telcordia GR-326-CORE compliant assemblies (General Requirements for Singlemode Optical Connectors and Jumper Assemblies – formerly Bellcore), where its high Tg and environmental robustness allow the termination to meet the specification. Note: optimal cure schedule required.

Specifications

Part number change: as of version 5.0, April 2021, the part number of this product changed from Opti-tec 5053-F-A to Opti-tec 5053-F-B. This is due to an unavoidable change in a formulation component. This change does not affect the product data-sheet specifications. The new formulation has passed internal testing and is deemed to be equivalent.

For optimal results, store away from acids, amines, strong alkalis and oxidising material. Static electricity and formation of sparks must be prevented. Keep only in the original container. Keep container tightly closed and upright, in a cool, well-ventilated place. Protect containers from damage. Bund storage facilities to prevent soil and water pollution in the event of spillage. The storage area floor should be leak-tight, jointless and not absorbent.
