Product Description
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.
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.

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.
