Product Description
Permabond® ET5422 is a high-performance, two-part epoxy adhesive formulated specifically for applications demanding exceptional toughness and high structural strength. This 2:1 mixable system features controlled-flow, thixotropic properties, making it highly effective for gap-filling applications while ensuring ease of mixing and application. It delivers excellent resistance to impact, vibration, and elevated temperatures, providing durable bonds across metals and composite materials.
Key features
- Exceptional toughness: Formulated to provide maximum impact and vibration resistance for highly stressed structural joints.
- Thixotropic rheology: Controlled flow characteristics allow the adhesive to be easily applied while remaining suitable for gap-filling applications up to 5 mm.
- High temperature performance: Delivers exceptional bond strength even at elevated temperatures, which can be further improved with a brief post-cure cycle.
Applications / Suitable for
- Structural bonding of metals (steel, aluminum, galvanized) and composites (carbon fiber, GFRP)
- Assemblies requiring high impact and vibration resistance
- Applications requiring controlled flow for gap filling or vertical application

General Properties
Chemistry Type
A:Epoxy Resin/B:Modified Polyamide
Mix Ratio
2:1 by volume 100:44 by weight
The amount of a constituent divided by the total amount of all other constituents in a mixture
Pot Life
180 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:1.14/ B:1.0
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.
Work life @25°C
24 hours
Work life is the amount of time we have to work with a material until it is no longer able to be easily worked and applied on a substrate.
It is based on the change in viscosity and it can rely on the application requirements.
Physical Properties

105,000 mPa.s
Viscosity (Part B)

Mechanical Properties
Impact Strength

Peel Strength
Cured 1hr @ 60°C: 270 N/25mm / Cured 5 days @ 23°C: 320 N/25mm
Thermal Properties
Glass Transition Temperature (Tg)
5d @ 23°C: 60°C/ 3d @ 23°C + 60min @ 80°C: 115°C °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.
