Product Description
Permabond® ET515 Two-Part Epoxy is a 1:1 mixable, semi-flexible toughened epoxy adhesive. It cures relatively fast at room temperature, reaching handling strength in just 20-30 minutes, and provides excellent adhesion to a diverse array of substrates including wood, metal, ceramics, plastics, and composites. Its semi-flexible nature provides good impact strength and makes it highly suitable for bonding dissimilar materials where differential thermal expansion is anticipated.
Key features
- Semi-flexible and toughened: Provides good impact strength and flexibility, accommodating differential thermal expansion between dissimilar bonded materials.
- Fast room-temperature cure: A relatively fast-curing epoxy that achieves handling strength in 20-30 minutes without the need for external heat.
- Versatile adhesion: Bonds strongly to a wide variety of substrates including metals, wood, ceramics, composites, and certain plastics.
Applications / Suitable for
- Bonding dissimilar materials subject to thermal cycling or expansion
- Structural bonding of wood, metal, ceramics, and composites
- Assemblies requiring a semi-flexible, impact-resistant joint

General Properties
Appearance
Colourless
Appearance at room temperature.
Chemistry Type
A:Epoxy Resin/B:Polyamine Hardener
Mix Ratio
1:1
The amount of a constituent divided by the total amount of all other constituents in a mixture
Pot Life
10 - 20 minutes
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed.
It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.
Solids
100 %
Specific Gravity
A:1.1/ B:1.1
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 (Part A)
15,000 mPa.s mPa.s
Viscosity (Part B)

Mechanical Properties
Elongation
20-40 %
Elongation is the process of lengthening something.
It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.
It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
Peel Strength
100-150 N/25mm
Thermal Properties
Glass Transition Temperature (Tg)
20 °C
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.
The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
Thermal Conductivity
0.34 W/m.K
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
15-25 kV/mm
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.
