processing

1
Clean surfaces
Prepare the bonding surfaces so they are clean, dry, and free of grease—degrease them with Permabond Cleaner A. Lightly sand aluminum and copper to remove the oxide layer.
2
Apply the adhesive directly
Permabond ES5681 ohne Mischen direkt aus dem Gebinde auftragen — als 1K-System keine Topfzeit-Limitierung. Lufteinschlüsse vermeiden.
3
Joining and securing components
Press the components together firmly. Use a clamping device or clamp to prevent the parts from moving while the adhesive cures.
4
Perform heat curing
Curing is achieved by applying heat—thermal curing. Typical conditions: 30 minutes at 150 °C in an industrial oven or using equivalent IR/hot-air curing. See the TDS for exact values.
5
Ultimate strength after cooling
After heat curing, allow the component to cool—final strength is achieved immediately after cooling. Unlike with two-component epoxies cured at room temperature, there is no need to wait 24 hours.

Important information

Important information
Please check with SILITECH Sales before placing an order.
storage
Store at 5 to 25 °C. One-component heat-curing epoxies have limited storage stability—reactivity decreases as storage temperature increases. Observe the expiration date.

Häufige Fragen zu Permabond ES5681

Practical questions regarding application and design — answered by SILITECH.

Spezial 1K-Epoxid für Engineering-Anwendungen. 1K-Epoxide werden ohne Mischen direkt verarbeitet und in einem Heat-Cure-Schritt ausgehärtet.

1-component epoxies are applied directly from the container without mixing—no pot life limitations, no mixing errors. Disadvantage: Heat curing required (industrial oven, IR lamp, or hot air). 2K epoxies cure at room temperature but require precise mixing and have a limited pot life. 1K is suitable for production lines with heat-cure infrastructure; 2K is suitable for workshops without an oven.

Heat curing. For exact conditions, see the Permabond Technical Data Sheet (TDS)—typically 30 minutes at 150 °C or an equivalent heat input (e.g., 60 min @ 120 °C).

1K heat-cure epoxies bond metals (steel, aluminum, copper), composites (CFRP, GFRP), ceramics, and select plastics (with heat resistance). Substrates must be able to withstand the curing temperature (typically 150 °C).

Permabond ES5681 hat keine spezifischen Industrie-Zulassungen wie UL94-V0 (siehe ES578 für flammwidrige Variante). Für allgemeine Industrieanwendungen ist das Produkt nach Permabond-Standards freigegeben.

Store at 5 to 25 °C. 1K heat-cure epoxies have limited storage stability—reactivity decreases as storage temperature increases. Store in a cool place for extended shelf life. Allow the adhesive to warm to room temperature before opening.
