About Opti-tec 5054-T High Temperature Epoxy Adhesive

Opti-tec™ 5054-T is a two component, thixotropic, heat curing epoxy. It is formulated for very high temperature resistance and can operate up to 350°C for short periods. Its structure gives the material outstanding environmental resistance including super heated steam at 135°C. Opti-tec 5054-T high temperature epoxy adhesive finds applications in fibre optics where superior thermal and environmental resistance is required. With a simple 1:1 mix ratio, it is supplied in a convenient side-by-side double syringe cartridge, complete with static mixing nozzles.

Opti-tec 5054-T is a high viscosity version of Opti-tec 5054.

Features & Benefits

  • Can withstand high temperature steam autoclaving and operate for short periods up to 350°C
  • Very long pot life of 12 hours after mixing
  • High surface energy allowing it to readily wet glass optical fibres. It develops strong adhesion to most materials used in fibre optics and optics, including metals, ceramics, glass and most plastics.
  • Low shrinkage on cure, which reduces internal stresses within the bond
  • Excellent impact and thermal shock resistance, with low internal stresses
  • High glass transition temperature results in excellent high temperature performance and creep resistance
  • Very high resistance to moisture, vapours and most chemicals.
  • Low outgassing and low vapour pressure – ideal sealing material for electronic and optical applications
  • May be gelled at 80°C prior to full cure


  • High temperature, high performance bonding and sealing
  • Endoscope manufacture and repair
  • Electronics repair
