Description
Industrial-Grade Epoxy for Superior Bonding Performance
Permabond® ET5422 is a high-performance, two-part epoxy adhesive specifically engineered for structural bonding applications in aerospace, automotive, and industrial manufacturing. Featuring exceptional shear and peel strength, ET5422 is designed to provide long-term durability in demanding environments, including high-temperature and high-vibration applications.
With its thixotropic (non-drip) consistency, long open time, and gap-filling capabilities, ET5422 ensures precise, reliable application—making it the go-to epoxy adhesive for aluminum bonding, composites, and metal substrates.
Key Features & Benefits
✔ High Shear & Peel Strength – Reliable structural bonding for metals, composites, and plastics.
✔ Long Open Time – Provides up to 3 hours of workability, allowing precise assembly.
✔ Thixotropic Formula – No-drip application for vertical and overhead bonding.
✔ Gap Filling Capabilities – Bonds uneven surfaces with up to 5mm gap fill.
✔ High Temperature Resistance – Withstands temperatures up to 115°C (post-cure).
✔ Impact & Vibration Resistant – Ideal for dynamic load-bearing applications.
✔ Accelerated Cure Option – Full cure in 1 hour at 82°C for faster processing.

Application Instructions
1️⃣ Surface Preparation – Clean surfaces with acetone or isopropanol. Lightly abrade metals for optimal adhesion.
2️⃣ Mixing – Use dual cartridges or a static mixer to ensure a consistent mix ratio.
3️⃣ Application – Apply adhesive to one surface and assemble within the usable pot life.
4️⃣ Curing – Clamp or fixture parts until handling strength is achieved. Accelerate curing with heat (1 hour at 82°C).
