Description
Opti-tec 5053 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.

Product improvements
For most fibre optic terminating applications, an improved and faster cure version of OPT 5053 is recommended - please see OPT 5053-F High Temperature Fast Cure Epoxy Adhesive.

Applications

  • Fibre optic terminating
  • Endoscope manufacture and repair
  • Optoelectronics
  • High temperature, high performance bonding
  • Electronic sealing
  • Medical device assembly

Fibre Optic Termination

Features

  • OPT 5053 has high surface energy. This and its 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.
  • OPT 5053 has excellent impact and thermal shock resistance.
  • OPT 5053's high glass transition temperature results in excellent high temperature performance and creep resistance.
  • OPT 5053 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.
  • OPT 5053 has a colour change upon cure, going from clear to deep translucent red.
  • OPT 5053 has been specially formulated to have very low skin sensitivity.
  • OPT 5053 has a long pot life and good handling characteristics.
  • OPT 5053 is 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.
  • OPT 5053, when cured, is considered non-cytotoxic and meets the requirements of the Elution Test, ISO 10993-5. Further ISO 10993 and USP Class VI qualification pending.
