Opti-tec 5013 Optically Clear, Fast Cure Epoxy Adhesive for Glass and Glass/Metal Bonding

1 5


Opti-tec 5013 is a two component, medium viscosity epoxy with high optical clarity. It has a fast room temperature cure, which can be accelerated by heat. Opti-tec 5013 is designed as an adhesive, or for small potting and encapsulation projects where high optical clarity, good wetting and medium viscosity are important.

Opti-tec 5013 can be used for bonding glass, quartz, metal and many plastics. It finds uses in assembly and repair of glass items where a clear adhesive is required.

Features & Benefits

  • Optically clear
  • Viscosity of 5,000-10,000 cps
  • Sets within minutes and cures within hours at room temperature. It reaches handling strength in 30 minutes. Full cure can be achieved in 10 minutes at 65°C.
  • High surface energy allows it to 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
  • Hard material after cure and can be polished
  • Good resistance to yellowing
  • Supplied in convenient side-by-side double syringe cartridges, complete with static mixing nozzles.

For best results, store away from amines, acids, oxidising agents, oxidising materials and strong alkalis. Static electricity and formation of sparks must be prevented and should avoid heat, flames, and other sources of ignition. 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.
