PERMABOND 795

Main features

  • Moderate-Viscosity Surface-Insensitive Adhesive
  • 0.18 mm Maximum Gap Fill
  • MIL-A-46050C/CID A-A-3097 Compliance

Product Description

Permabond® 795 Cyanoacrylate is a moderate-viscosity, surface-insensitive adhesive designed to rapidly bond a wide variety of substrates, including difficult acidic surfaces like wood and plated metals. This 100% reactive, solvent-free formulation minimizes frosting and fogging during cure, making it ideal for clean, high-speed production lines. It reliably bonds plastics, metals, ceramics, and elastomers, achieving handling strength in just seconds without the need for mixing or heat curing.

Key features

  • Extremely fast setting: Polymerizes rapidly upon contact with surface moisture, delivering fixture handling times of approximately 4 seconds on steel, rubber, and phenolic.
  • Surface insensitive: Expertly engineered to form high-strength bonds on typically challenging acidic surfaces, such as wood and plated materials.
  • Industry approved: Meets stringent military and commercial specifications, including MIL-A-46050C Type II Class 3 (existing designs) and CID A-A-3097 Type II Class 3 (new designs).

Applications / Suitable for

  • Bonding acidic surfaces such as wood and plated surfaces
  • Adhering plastics, metals, ceramics, and elastomers
  • High-speed production lines requiring fast curing and moderate gap filling

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 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.

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.
