PERMABOND HH040

Main features

  • 5,000 mPa s Retaining Viscosity
  • General-Purpose Maximum Gap Fill
  • 14 MPa Retaining Shear

Product Description

PERMABOND HH040 is a single-component anaerobic retaining compound for close-fitting cylindrical metal assemblies. Viscosity is 5,000 mPa s and shear strength is 14 MPa, with general-purpose retaining and maximum-gap filling within its product class. The adhesive is used to retain and seal cylindrical metal parts, including shaft-and-hub type assemblies, where anaerobic cure is appropriate. Its 5,000 mPa s viscosity gives the adhesive a higher-body profile for controlled placement in cylindrical interfaces. HH040 combines retaining strength, sealing function and gap-filling capability for close-fitting cylindrical metal joints.

Key features

  • 5,000 mPa s Retaining Grade: Viscosity provides a higher-body anaerobic profile for cylindrical metal assemblies.
  • 14 MPa Shear Strength: Shear strength is 14 MPa for the retaining compound.
  • Maximum-Gap Filling: The retaining compound is intended for general-purpose use with maximum-gap filling within its product class.

Applications

Retaining and sealing close-fitting cylindrical metal parts, including shaft-and-hub type assemblies.

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.
