PERMABOND MM115

Main features

  • 10-Minute Handling Strength
  • Controlled Medium-Strength Off-Torque
  • Serviceable Thread Locking and Sealing

Product Description

Permabond MM115 is a blue, single-part anaerobic threadlocker and sealant for metal bolts, nuts, and screws that may require service disassembly. The thixotropic methacrylate formulation cures at room temperature, reaches handling strength on M10 steel in about 10 minutes at 23 deg C, and develops full strength after 24 hours. Its medium-strength cured joint provides 16 N m breakaway torque and 7 N m prevailing torque on M10 steel under ISO 10964. Applications include machinery and equipment fastener retention where ordinary tools are required for later disassembly.

Key features

  • Serviceable Medium Strength: Allows disassembly of threaded fasteners with ordinary tools.
  • 10-Minute Handling: Reaches handling strength on M10 steel in about 10 minutes at 23 deg C.
  • Controlled Off-Torque: Provides 16 N m breakaway and 7 N m prevailing torque on M10 steel.

Applications

Applications include locking and sealing metal bolts, nuts, and screws in machinery and equipment that may require service or maintenance disassembly.

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.
