High Temperature Resistant Cyanoacrylate

Permabond introduces new high temperature resistant cyanoacrylate adhesives!

PERMABOND® 825 is a low viscosity cyanoacrylate adhesive that provides higher strength at high temperature. This fast-setting cyanoacrylate bonds metals, rubbers, plastics, and more. Permabond 825 resists up to 392°F (200°C) and has excellent retention of strength during thermal aging. PATENTED TECHNOLOGY

high temperature resistant cyanoacrylateFeatures and Benefits
  • Strong bonds that resist up to 392°F (200°C)
  • No secondary or post-cure required to achieve temperature resistance
  • Low viscosity 120 cPs/mPa.s
  • Tolerates stresses at high temperature
  • Does not require zero-gap – better thermal stability with a larger gap
  • Higher strength retention after thermal aging
  • 2500 psi (17 MPa) bonds to mild steel at 77°F (25°C)
  • 600 psi (4MPa) bonds to mild steel at  300°F (150°C)


Typical ethyl cyanoacrylates resist up to 180°F (82°C) with special grades resisting as high as 250°F (120°C). Generally, methyl cyanoacrylates resist 195°F (90°C).  Specialty allyl cyanoacrylates can resist up to 482°F (250°C). However, these require a post-cure or secondary heat cure to achieve the temperature resistance.
