Main features
- 5-Minute Steel Handling Time
- 30 MPa Shear Strength
- High-Temperature Chemical Resistance
Product Description
Permabond® HM162 is a medium-viscosity anaerobic retaining compound that cures rapidly when confined between close-fitting metal parts. Engineered to form an extremely tough bond, it excels in applications involving cylindrical parts where very high strength and improved fatigue life are paramount. In its uncured state, the liquid adhesive wets out metal surfaces perfectly, keying into surface irregularities and effectively filling the space between mated components.
Key features
- Rapid curing: Achieves handling strength on steel in just 5 minutes at room temperature, significantly accelerating assembly processes.
- Superior performance: Delivers very high shear strength (30 MPa) and improved fatigue life, ensuring durable bonds under high stress.
- High temperature resistance: Specially formulated to maintain excellent bond strength and integrity in elevated temperature environments.
Applications / Suitable for
- Retaining and sealing cylindrical metal parts (up to 0.2 mm gap)
- Assemblies requiring improved fatigue life and high shear strength
- Applications operating in high-temperature or chemically harsh environments

Specific Gravity
1.1
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
Physical Properties
Viscosity
1,000 mPa.s
Viscosity is a measurement of a fluid’s resistance to flow.
Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.
A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.
The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application

Electrical Properties
Dielectric Strength
11 kV/mm
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material.
Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property.
As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
Thermal Properties
Thermal Conductivity
0.19 W/m.K
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.
Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
