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
