Product Description
Permabond® HM118 is an excellent general-purpose anaerobic threadlocker designed for the permanent assembly of bolts, nuts, and screws. Formulated as a non-drip, thixotropic red liquid, it prevents vibration loosening and provides high off-torque strength once fully cured at room temperature. It cures reliably and rapidly on a wide variety of metal surfaces, including steel, cadmium, zinc, and other plated fasteners, making it highly effective for machinery and equipment manufacturing.
Key features
- Military and ASTM approved: Tested to meet the stringent requirements of MIL-S-46163A and ASTM D5363 (sections 5.1.1, 5.1.2, and 5.2).
- High structural strength: Delivers a high breakaway torque (23 N-m) for permanent assemblies, effectively preventing loosening caused by vibration.
- Application versatility: The thixotropic nature ensures the adhesive remains in place on threads, while simultaneously lubricating those threads to facilitate easier assembly.
Applications / Suitable for
- Permanent assembly of bolts, nuts, and screws (up to M20 / 3/4")
- Locking fasteners on steel, cadmium, zinc, and other plated surfaces
- Machinery and equipment manufacturing environments

Chemistry Type
Methacrylate esters
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
1,800 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
0.2 mm
Maximum thread size
M20 ¾
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.
