Product Description
Permabond ET5401 is a fast-curing 2K structural adhesive in a 2:1 ratio — designed for clocked line production with high strength requirements on metal and composite.
With a pot life of only 10–12 minutes, ET5401 is one of the fastest structural adhesives in the Permabond range — fast enough for clocked production, but with premium strength (20–30 N/mm² steel, 22–24 N/mm² carbon fiber).
Fast-curing, high-strength, two-component structural adhesive — combining a short pot life (10–12 min) with top shear strength on steel and carbon fiber. The choice for clocked line production with structural requirements.

Frequently asked questions about Permabond ET5401
Practical application and design questions — answered by SILITECH.
Fast-curing 2-component structural adhesive 2:1 — 10–12 min pot life, 20–30 N/mm² steel. The 2-component epoxy is mixed in a 2:1 volume ratio and offers a pot life of 10–12 minutes @ 23 °C.
Mix both components in a 2:1 ratio by volume — using a mixing nozzle for dual cartridges, weigh precisely for larger containers. Apply within the pot life (10–12 minutes @ 23 °C) and join components. Full curing typically occurs after — at room temperature.
The pot life of Permabond ET5401 is typically 10–12 minutes 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 ET5401 bonds reliably to: steel: 20–30 N/mm²; carbon fiber: 22–24 N/mm². For thermoplastic substrates, test compatibility before series production.
Permabond ET5401 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 ET5401 is a fast-setting structural adhesive 2:1 — 10–12 min pot life, high strength (2:1 volume mix, 10–12 minutes @ 23 °C pot life). Permabond ET540 is a long pot life adhesive (2:1, 120–150 min pot life) — very long pot life.
From the Permabond 2K epoxy range, select according to application, mixing ratio, and strength requirements: Permabond ET5401 (fast-setting structural adhesive 2:1 — 10–12 min pot life, high strength); Permabond ET540 (long pot life); Permabond ET5411 (high temperature); Permabond ET5428 (black, fast-setting, high strength).
