Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg
Main features
- High-Strength High-Temperature Threadlocking
- DVGW/KTW-BWGL Approval Scope
- Thread Lubrication and Vibration Resistance
Product Description
Permabond® HH131 is a high-strength, anaerobic threadlocker and sealant engineered to deliver exceptional performance in extremely high-temperature environments. It cures reliably in the absence of air between tight-fitting metal components, making it ideal for locking bolts, nuts, and screws that require permanent assembly. In addition to its temperature resistance, HH131 lubricates threads to facilitate easier assembly and provides superior resistance against harsh chemicals, vibration, and environmental factors.
Key features
- High temperature resistance: Specially formulated to maintain structural integrity and high breakaway torque even in environments subject to elevated temperatures.
- Industry approved: Holds DVGW Approval for Gas applications and is KTW-BWGL Drinking Water Compliant, ensuring safe use in regulated utility systems.
- High strength & vibration resistance: Provides a permanent, very high-strength lock (Breakaway torque 27 N-m) that effectively prevents fasteners from loosening due to vibration or shock.
Applications / Suitable for
- Permanent assembly of bolts, nuts, and screws operating in high-temperature environments
- Gas and drinking water systems requiring DVGW and KTW-BWGL compliance
- Assemblies requiring vibration resistance and lubrication during installation

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
7,500 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
0.3 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.
Other Properties
Maximum thread size
M56
