Description

Opti-tec 5007 is a two component, low viscosity clear epoxy adhesive with a two hour pot life, capable of curing within 20 minutes at 75°C. Opti-tec 5007 has excellent sealing and bonding characteristics due to its viscosity and wetting properties. Cured material has high shock and impact resistance with outstanding chemical, moisture and thermal resistance.

The adhesive is designed for fibre optic terminating (pot and polish of fibre optic connectors), where its ability to cure at ambient or minimal raised temperatures gives process enhancements. It can be used for bonding and potting optical components such as prisms, lenses, LED displays and fibres, and for general precision bonding.

Features & Benefits

  • Clear adhesive with a viscosity of 1000 cps
  • Also available in a blue version (Opti-tec 5007B) for ease of inspection in fibre terminating
  • Two hour pot life after mixing and cures within 16-24 hours at room temperature. Cure can be achieved in 20 minutes at 75°C or 5 minutes at 100°C.
  • 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 many plastics.
  • Good impact and thermal shock resistance
  • Low exotherm, low shrinkage, low stress cure
  • Excellent chemical and moisture resistance with a very low exotherm, making it suitable for small potting and encapsulation applications
  • 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 5007B, when cured, is considered non-cytotoxic and meets the requirements of the Elution Test, ISO 10993-5.

Applications

  • Fibre optic terminating, multimode fibres
  • Endoscope manufacture and repair
  • Optical potting & bonding
  • Medical device assembly – ISO 10993-5
  • Glass bonding
