- Vibration/Corrosion-Resistant Thread Retention
Product Description
Permabond® HH120 is an excellent general-purpose anaerobic threadlocker and sealant designed for the permanent assembly of bolts, nuts, and screws. Featuring a high-viscosity, non-drip, and thixotropic formulation, it is particularly well-suited for coarse threaded fasteners where precise application without slumping is required. It cures fast and reliably at room temperature on various metal surfaces, including steel, cadmium, zinc, and other plated fasteners, providing exceptional environmental and corrosion resistance.
Key features
- Military and Industry specified: Tested to meet the strict requirements of MIL-S-46163A, MIL-S-22473E, and ASTM D5363 standards.
- High viscosity & Non-drip: The 7,000 cP thixotropic formulation ensures the adhesive stays in place, making it ideal for coarse threads and blind holes.
- Vibration and corrosion protection: Reliably prevents vibration loosening while providing a 100% solid, environmentally friendly barrier against corrosion.
Applications / Suitable for
- Permanent locking of coarse threaded fasteners, bolts, nuts, and screws
- Sealing pipe flanges and retaining worn bearings
- Machinery and equipment manufacturing

Specific Gravity
1.2
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.
Work life @25°C
0.5 hours
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.
It is based on the change in viscosity and it can rely on the application requirements.
Physical Properties
Viscosity
7,000 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
Other Properties
Maximum gap fill
0.25 mm mm
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.
