PERMABOND HM165

Main features

  • Larger-Tolerance Cylindrical Retention
  • Thixotropic High-Viscosity Gap Filling
  • High-Temperature Very-High-Strength Retention

Product Description

Permabond HM165 is a high-viscosity, thixotropic anaerobic retaining compound for cylindrical metal assemblies with larger tolerances and elevated-temperature requirements. Its viscosity is 25,000 cP at 2 rpm and 10,000 cP at 20 rpm at 25 deg C, and the product fills gaps up to 0.3 mm. Typical handling strength on M10 steel is reached in 15-20 minutes at 23 deg C, with full strength in 24 hours. Cured HM165 develops typical 20 MPa shear strength on a steel collar-and-pin test to ISO 10123. It is a very-high-strength retainer when gap filling and high-temperature resistance are key selection needs.

Key features

  • Larger-tolerance cylindrical retention: High viscosity and thixotropic behavior allow use with larger clearances in cylindrical metal assemblies.
  • 0.3 mm maximum gap fill: Fills gaps up to 0.3 mm for slip- and clearance-fit retaining applications.
  • High-temperature retaining grade: The product is specified for cylindrical retention where high-temperature resistance is required.

Applications

Retaining cylindrical metal parts; slip/clearance fits with larger tolerances; higher-temperature retaining applications.

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.
