PERMABOND HM160

Main features

  • Medium-Viscosity High-Strength Retaining
  • Lighter Press-Fit Assembly Tolerances
  • MIL-R-46082B/ASTM D5363 Compliance

Product Description

Permabond® HM160 is a medium-viscosity, high-strength anaerobic retaining compound engineered to secure and seal cylindrical metal assemblies. It cures when confined in the absence of air between close-fitting metal surfaces, transforming into a tough, hard plastic that keys into surface irregularities to fill the space between mated parts. By augmenting press fits, it allows for looser manufacturing tolerances and lighter press fits, ultimately reducing machining costs and preventing fretting corrosion and vibration-induced loosening.

Key features

  • Cost-reducing design: Allows the use of lighter press fits and easier-to-assemble tolerances, decreasing required machining precision and manufacturing costs.
  • Military and ASTM specified: Thoroughly tested to meet the demanding requirements of MIL-R-46082B (Type II) and ASTM D5363 (AN 0412 Group 04 Class 1 Grade 2).
  • Extends component life: Reduces the stress typically caused by heavy press fits, dresses worn parts, and completely seals the joint against air and moisture to prevent corrosion.

Applications / Suitable for

  • Bonding slip, press, and shrink-fitted cylindrical assemblies
  • Improving alignment and filling space between bearing rings and housings
  • Dressing worn cylindrical parts to keep machinery online

Specific Gravity
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
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
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.
11 kV/mm
Thermal Properties
Thermal Conductivity
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.
