Permabond ET5429 is a high-strength 2K structural adhesive in a 2:1 ratio — the all-round choice with a balanced pot life and 23–28 N/mm² steel strength.

ET5429 is positioned between the fast-setting ET5401 and the strongest ET5428 black — offering a balanced ratio of pot life to final strength. The black and white component design allows for visual mixing control.

APPLICATION PROFILE

High-strength structural adhesive in a 2:1 ratio — 23–28 N/mm² steel shear strength, balanced profile between ET5401 (faster) and ET5428 (higher strength). The all-round choice in the 2:1 class.

Processing

1
Clean surfaces
Bonding surfaces must be clean, dry, and free of grease. Degrease with Permabond Cleaner A or a solvent (acetone, isopropanol). Lightly sand aluminum and copper to remove oxide layers.
2
Mix components A + B
For twin cartridges: attach the mixing nozzle and press evenly (2:1 volume ratio mixing ratio). For larger containers: weigh resin and hardener in the correct ratio and mix thoroughly until no streaks are visible. Avoid air entrapment.
3
Apply adhesive + join components
Apply the mixed adhesive to one bonding surface within the pot life (—). Join the components with sufficient pressure to distribute the adhesive over the entire bonding surface.
4
Fix components during curing
Use a clamping device or clamp to ensure the components do not move during curing. Wait for handling strength and functional strength according to the TDS.
5
Full cure at room temperature
Final strength is typically achieved after 24 hours at 23 °C. Increasing the temperature by 8 °C halves the curing time; lower temperatures slow down the process. If necessary, optionally post-cure at 60–80 °C for maximum strength.

Frequently asked questions about Permabond ET5429

Practical application and design questions — answered by SILITECH.

High-strength 2-component structural adhesive 2:1 — 23–28 N/mm² steel, balanced profile. The 2-component epoxy is mixed in a 2:1 volume ratio and offers a pot life of —.

Mix both components in a 2:1 ratio by volume — using the mixing nozzle for dual cartridges, weigh precisely for larger containers. Apply within the pot life (—) and join components. Full curing typically occurs after — at room temperature.

The pot life of Permabond ET5429 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 ET5429 bonds reliably to: Steel: 23–28 N/mm². For thermoplastic substrates, test compatibility before series production.

Permabond ET5429 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 ET5429 is a high-strength structural adhesive 2:1 — 23–28 N/mm² steel (2:1 volume parts mix, — pot life). Permabond ET5428 is a high-strength (2:1, 10–20 min pot life) — premium black variant.

From the Permabond 2K epoxy range, select according to application, mixing ratio, and strength requirements: Permabond ET5429 (High-strength structural adhesive 2:1 — 23–28 N/mm² steel); Permabond ET5428 (Highest strength); Permabond ET5401 (Fast 2:1); Permabond ET540 (Long pot life). For aerospace applications, see ET515 (Aircraft seat trays); for food applications, see ET5162 (EU 10/2011 + FDA); for thermal conductivity/fire protection, see ET5441 (UL94-V0).
