  • Post-Cured Service up to 250 deg C
  • 15 to 20-Second Steel Fixture
  • MIL-A-46050C Type V Class 2 Compliance

Product Description

Permabond® 920 Cyanoacrylate is an allyl-based, low-viscosity adhesive explicitly designed to deliver extreme high-temperature resistance alongside rapid, high-strength bonding. This 100% reactive, solvent-free liquid cures quickly at room temperature but features a unique secondary curing mechanism that is activated by heat. When subjected to a proper post-curing schedule at 150°C (302°F), the adhesive forms exceptionally resilient bonds capable of withstanding environmental temperatures up to 250°C (482°F).

Key features

  • Extreme temperature resistance: Secondary thermal curing allows bonded assemblies to reliably withstand continuous temperatures up to 250°C (482°F).
  • Fast setting: Delivers fixture handling times of 15-20 seconds on steel and 10-15 seconds on rubbers and phenolics at room temperature.
  • Medical and military approved: Approved to MIL-A-46050C Type V Class 2 specifications for existing designs and has successfully passed Cytotoxicity testing.

Applications / Suitable for

  • Assemblies exposed to extreme high-temperature environments (up to 250°C after post-cure)
  • Bonding metals, including steel, aluminum, and zinc
  • Medical devices and military applications requiring specific approvals

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

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.
