Permabond HM165 Anaerobic Retainer

Permabond HM165

Permabond HM165 is a high viscosity anaerobic retaining compound that cures when confined between metal parts to form a tough bond. It is best suited for cylindrical parts and where high temperature resistance is required. The high viscosity and thixotropic effect of the material allows for larger tolerances.

Features & Benefits:

  • Very high strength 
  • Easy to apply 
  • Improved fatigue life 
  • Excellent chemical resistance 
  • High temperature resistance
