About Opti-tec 5013-1 Optically Clear, Fast Cure Epoxy Adhesive

Also available to buy online at  Available at Intertronics.shop

Opti-tec 5013-1 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 5013-1 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 5013-1 can be used for bonding glass, quartz, metal and many plastics. It finds uses in the 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.


  • Glass and metal bondingBonded glass and metal staircase
  • Repair of glass, wood, ceramic, metal
  • Repair or restoration of minerals, gems and quartz crystals
  • Optical assembly, optical filters, lenses, prisms
  • Optical encapsulation & glob topping, small volume casting or potting
  • Opto-electronics, photonics, LEDs
