Product Description
Permabond ET5422 is a premium 2K epoxy with top shear strength on carbon fiber composites — the choice for the most demanding CFRP structural bonding applications in sporting goods, vehicle and mechanical engineering.
With a shear strength of 20–30 N/mm² on carbon fiber, ET5422 is one of the strongest 2K epoxies in the Permabond range for composite bonding. Its 100:44 weight ratio is optimized for maximum final strength.
The steel strength of 22–26 N/mm² is also in the top range. ET5422 is the premium choice when maximum strength is required—for example, for load-bearing CFRP structures in rotor blades, sporting goods, or vehicle construction.
Premium carbon fiber adhesive with superior shear strength — 22–26 N/mm² on steel and 20–30 N/mm² on carbon fiber. Specifically optimized for composite structural bonding in mechanical engineering, sporting goods and vehicle manufacturing.

Frequently asked questions about Permabond ET5422
Practical application and design questions — answered by SILITECH.
Premium high-strength 2K epoxy — 22–26 N/mm² steel, 20–30 N/mm² carbon fiber bonding. The 2K epoxy is mixed in a 100:44 weight ratio and offers a pot life of —.
Mix both components in a 100:44 ratio by weight — using a mixing nozzle for dual cartridges, weigh precisely for larger containers. Apply within the pot life (—) and join components. Full curing typically occurs after 24 hours at room temperature.
The pot life of Permabond ET5422 is typically — at 23 °C. Higher temperatures shorten, lower temperatures lengthen the pot life. Mixing quantities above approximately 100 g may gel more quickly due to an exothermic reaction.
Permabond ET5422 bonds reliably to: steel: 22–26 N/mm²; carbon fiber: 20–30 N/mm². For thermoplastic substrates, test compatibility before series production.
Permabond ET5422 does not have specific industry-specific approvals such as EU 10/2011 (food), UL94 (fire protection), or Boeing/Airbus (aerospace). For general industrial applications, the product is approved according to Permabond standards.
Permabond ET5422 is a premium, high-strength 2-component epoxy 100:44 — a carbon fiber champion (20–30 N/mm²) (100:44 parts by weight mix, pot life). Permabond ET514 is a standard 1:1 (1:1, 30–50 min pot life) — easy 1:1 mixing.
