Product Description

PERMABOND® 2050 Flexible Cyanoacrylate Adhesive is a medium-high-viscosity, single-component ethyl cyanoacrylate adhesive designed for flexible, semi-porous, and dissimilar-material bonding. Its toughened formulation provides improved peel performance together with resistance to impact, vibration, thermal shock, and thermal cycling. The adhesive has a viscosity of 1,200–1,800 mPa·s at 25 °C and fills gaps up to 0.2 mm. Typical handling strength is reached in 5–15 seconds depending on the substrate, with full strength developing in 24 hours. It is suitable for plastics, elastomers, and metal assemblies where a more flexible instant adhesive bond is required.

Key features

  • Flexible, toughened formulation: Provides improved peel strength and resistance to impact, vibration, thermal shock, and thermal cycling.
  • Fast fixture performance: Typical handling strength is reached in 5–15 seconds depending on the bonded substrate.
  • Controlled medium-high viscosity: A viscosity of 1,200–1,800 mPa·s supports accurate dispensing and gap filling up to 0.2 mm.

Applications / Suitable for

  • Bonding flexible or semi-porous surfaces
  • Bonding dissimilar materials
  • Assemblies exposed to vibration or impact
  • Applications exposed to thermal shock or thermal cycling
  • Bonding plastics, elastomers, and metals

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.
