Permabond HM1642 Anaerobic Retainer

Permabond HM1642 is a high viscosity retaining compound that cures when confined between metal parts to form an extremely tough bond.

Permabond HM1642 Anaerobic Retainer

In the uncured, liquid state, the adhesive wets the metal surfaces, keying into all surface irregularities and fills the gaps between the bonded parts. It allows machining tolerances to be relaxed; helping reduce manufacturing costs. It is fast-curing and can be used on less reactive metals such as stainless steel.

Features & Benefits

  • Rapid cure
  • Very high strength
  • Improved fatigue life
  • Excellent chemical resistance
  • Good gap filling


  • Bonding metal surfaces in demanding conditions

Surface Preparation

  • Surfaces should be clean, dry, and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces.
  • Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.


Directions for Use

  • Apply a circumferential bead, preferentially to the female component. Assemble with a twisting action.
  • For larger components use thixotropic products to prevent run off.
  • Take care to ensure adhesive does not enter ball races or other mechanisms.
