About Opti-tec 5053 High Temperature Epoxy Adhesive

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

Opti-tec 5053, when cured, is considered non-cytotoxic and meets the requirements of ISO 10993-5. It is a suitable candidate for applications in the medical device market – for example, endoscopes or sensors.

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

Fibre Optic Termination

Features & Benefits

  • Opti-tec 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.
  • Opti-tec 5053 has excellent impact and thermal shock resistance.
  • Opti-tec 5053’s high glass transition temperature results in excellent high temperature performance and creep resistance.
  • Opti-tec 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.
  • Opti-tec 5053 has a colour change upon cure, going from clear to deep translucent red.
  • Opti-tec 5053 has been specially formulated to have very low skin sensitivity.
  • Opti-tec 5053 has a long pot life and good handling characteristics.
  • Opti-tec 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.
  • Opti-tec 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.

For best results, store away from strong alkalis, oxidising material, acids, amines and strong oxidising agents. 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 and protect from freezing and direct sunlight. 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.
