PERMABOND HM161

Main features

  • Slip-Fit Cylindrical Retention with 0.25 mm Gap Fill
  • Fast Slip-Fit Assembly Handling
  • High-Shear Retention for Mated Metal Parts

Product Description

Permabond HM161 is a one-part anaerobic retaining compound for cylindrical metal parts and slip-fit assemblies. The liquid cures when confined between mating metal surfaces, unitizing the parts and limiting relative movement that can contribute to wear, erosion and pitting. It fills gaps up to 0.25 mm and reaches typical handling strength on M10 steel in 10 minutes at 23 deg C. After cure, HM161 develops typical 24 MPa shear strength on a steel collar-and-pin test to ISO 10123. Its 2,000 cP viscosity balances gap filling with a liquid application profile for cylindrical retention.

Key features

  • Slip-fit cylindrical retention: Retains mated cylindrical metal parts and slip-fit assemblies.
  • 0.25 mm gap fill: Fills gaps up to 0.25 mm between mating metal parts.
  • High cured shear strength: Typical shear strength is 24 MPa on a steel collar-and-pin test to ISO 10123.

Applications

Retaining cylindrical metal parts; slip-fit assemblies; prevention of movement, wear and corrosion between mated metal parts.

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.

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.
