Permabond HM162 is a high-strength anaerobic shaft-hub adhesive (retainer) — with a shear strength of 30 MPa, it is the strongest member of the anaerobic family for highly stressed cylindrical fits.

With a viscosity of 1,000 mPa·s, HM162 is low-viscosity and fills adhesive gaps up to 0.2 mm. Its high shear strength of 30 MPa qualifies the product for the most demanding shaft-hub connections—bearings, bushings, and torque transmission applications in heavy industry.

With a breakaway strength of 32 N·m and a further strength of 57 N·m, HM162 is in the high-strength range — disassembly typically requires heating. Its low viscosity ensures complete gap hardening, even in tightly toleranced H7/h6 fits.

SPECIAL FEATURE

30 MPa shear strength — the highest value in the Permabond Anaerobic family. High-strength shaft-hub adhesive for highly stressed cylindrical fits. Low viscosity for tightly toleranced adhesive gaps down to 0.2 mm.

Processing

1
Clean surfaces
Bonding surfaces must be clean, dry, and free of grease. Degrease with Permabond Cleaner A or a solvent (acetone, isopropanol). Rough surfaces (~25 µm) result in higher bond strength than polished ones.
2
Apply adhesive
Apply Permabond HM162 directly from the bottle — for through holes, apply a stripe along the thread length; for blind holes, apply a few drops to the bottom. Do not touch the tip to metal surfaces (this will cause premature hardening in the bottle).
3
Joining components
Insert the screws and tighten to the desired torque. For shaft-hub fits, assemble the components before the adhesive begins to cure.
4
Allow to cure
Anaerobic curing begins in the absence of air and upon contact with metal. Handling strength is typically achieved after 15 minutes, functional strength after 1 hour, and full strength after 24 hours at 23 °C.
5
Accelerate curing (optional)
On inactive surfaces (stainless steel, zinc, aluminum) or at low temperatures, Permabond A905 activator can be used — apply to one bonding surface, allow to flash off, then apply adhesive to the other side.

Important Notes

Not suitable for / Important notes
Disassembly typically requires heating above 200 °C. For inactive surfaces, use A905 activator. Not for contact with oxygen.
Storage
Store at 5 to 25 °C. Anaerobic adhesives lose their reactivity upon contact with metal — do not touch the tip of the bottle to metal surfaces, and do not pour adhesive back into the bottle.

Frequently asked questions about Permabond HM 162

Practical application and design questions — answered by SILITECH.

Permabond HM162 is an anaerobic acrylic adhesive with a viscosity of 1,000 mPa·s and a gap-filling capacity of up to 0.2 mm. This high-strength, low-viscosity shaft-hub adhesive boasts a shear strength of 30 MPa, the highest value in the anaerobic family. Anaerobic adhesives cure in the absence of air and in contact with metal—ideal for tight-tolerance metallic joints.

Anaerobic adhesives like Permabond HM162 remain liquid in the bottle (due to contact with air and oxygen) and only begin to harden after bonding under anaerobic conditions and metal-to-metal contact. Curing starts at the metal surface and progresses into the bond gap. The product cures quickly on steel and copper; on stainless steel and zinc, the Permabond A905 activator may be beneficial.

Yes — Permabond HM162 is a low-strength threadlocker (32 N·m breakaway torque) and can be loosened at any time with standard tools without heating. Designed for maintenance and service.

Permabond HM162 does not have specific industry approvals such as WRAS or KTW (drinking water). For general industrial applications, the product is approved according to Permabond's internal specifications; however, product-specific testing prior to series production is recommended.

Permabond HM162 typically reaches handling strength after 15 minutes and functional strength after 1 hour at 23 °C on M10 steel. Final strength is reached after 24 hours. On inactive surfaces (stainless steel, zinc) or at low temperatures, the curing time is extended—Permabond A905 activator accelerates the process.

Permabond HM162 is a high-strength, low-viscosity shaft-hub adhesive (1,000 mPa·s viscosity, 0.2 mm gap filling, 32 N·m breakaway torque). Permabond A1042 is a high-strength, fast-curing adhesive (—, 0.25 mm, 30 N·m breakaway torque) — A-series, fast curing. Both belong to the anaerobic Permabond A-series.

The choice depends on the application: Permabond HM162 (high-strength, low-viscosity shaft-hub adhesive); Permabond A1042 (high-strength, fast-curing); Permabond HM163 (high-strength, medium-viscosity); Permabond HM165 (high-strength paste). For inactive surfaces (stainless steel, zinc, aluminum), Permabond A905 activator be used to accelerate curing.
