Description

Opti-tec 5001 is a two component, very low viscosity optical epoxy with very high optical clarity. It has a long pot life and can be cured at room temperature or at 65°C for 1 hour. Opti-tec 5001 is designed for potting, encapsulation and adhesion of components where high optical clarity, good wetting and low viscosity are important.

Features & Benefits

  • High optical clarity with excellent resistance to yellowing
  • Clear, water white with a low viscosity of 100 cps.
  • Room or low temperature cure
  • Low fluorescence
  • High surface energy and low viscosity allows it to readily wet and wick between surfaces. It develops strong adhesion to most materials used in optics, including metals, ceramics, glass and most plastics
  • Good impact and thermal shock resistance, with low internal stresses due to low shrinkage on cure
  • Cures to a hard, glass-like material which can be polished
  • Good chemical and moisture resistance
  • Opti-tec 5001 is also available in a translucent white version

Applications

  • Optical assembly, optical filters
  • Glass bonding
  • Plastic fibre optics
  • Opto-electronics, photonics
  • Potting or encapsulation where high optical clarity is required: thin rock sections, geology samples, relics and artifacts, tissue samples, petrology

Ordering Information

Opti-tec 5001 is available in twinpacks or in bulk kits.

Twinpack packaging

The twinpack is a clear film sachet, with the resin and hardener separated by a removable clip and rail divider. Click here for twinpack mixing instructions.

Standard twinpack size is 4g total weight. Opti-tec 5001 twinpack sachets are packaged in quantities of 5, sealed into a protective aluminium foil pouch. After opening pouch, use adhesive twinpacks within a few days, or tightly reseal the pouch with the enclosed desiccant to preserve shelf-life.

Standard 500g bulk kit comprises two bottles, one each of Part A and Part B.

Part number Description
OPT5001-4G 5 x 4g twinpack sachets

For best results, store away from strong oxidising agents, strong alkalis, amines, oxidising materials, and acids. Keep only in the original container. Keep container upright and tightly closed, 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.
