Permabond ET5011 is an optically clear 2K epoxy for encapsulation, embedding, and visible applications — remains transparent after curing, ideal for decorative and potting applications.

Unlike standard industrial epoxies, ET5011 is optimized for optical clarity — the cured bond remains transparent like glass and is suitable for both visible bonding and encapsulation of components.

The 100:94 weight ratio provides a balanced processing and strength profile. ET5011 is often used for jewelry, display, and decorative applications.

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 mixing nozzle, press evenly (100:94 parts by weight 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 after typically — 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.

Important Notes

Important Notes
Mix thoroughly, otherwise the adhesive will remain partially tacky. For embedding applications, pour slowly to avoid air entrapment.
Storage
Store at 5 to 25 °C. Keep 2K epoxy components in closed packaging — especially protect the hardener from moisture.

Frequently asked questions about Permabond ET5011

Practical application and design questions — answered by SILITECH.

Optically clear 2K epoxy — embedding, encapsulation, decorative applications. The 2K epoxy is mixed in a 100:94 parts by weight ratio and offers a pot life of —.

Mix both components in a ratio of 100:94 parts by weight — for dual cartridges with a mixing nozzle, for larger containers weigh out precisely. Apply within the pot life (—) and join the parts together. Full cure typically after — at room temperature.

The pot life of Permabond ET5011 is typically — at 23 °C. Higher temperatures shorten, lower temperatures extend the pot life. Mixing quantities above approximately 100 g can cure faster due to exothermic reaction.

Permabond ET5011 typically bonds metals, composites, and plastics. For substrate-specific values, see the TDS.

Permabond ET5011 has no specific industry approvals such as EU 10/2011 (food contact), UL94 (flame retardancy), or Boeing/Airbus (aerospace). For general industrial applications, the product is approved according to Permabond standards.

Permabond ET5011 is an optically clear 2K epoxy — for embedding and encapsulation (100:94 parts by weight mix, — pot life). Permabond ET505 is clear amber (1:1, — pot life) — amber-colored instead of clear.

From the Permabond 2K epoxy range, select based on application, mixing ratio, and strength requirements: Permabond ET5011 (Optically clear 2K epoxy — for embedding and encapsulation); Permabond ET505 (Clear amber); Permabond ET514 (Standard high strength); Permabond ET515 (Aerospace flexible). For aerospace, see ET515 (Aircraft Seat Trays); for food contact, ET5162 (EU 10/2011 + FDA); for thermal conductivity/fire protection, ET5441 (UL94-V0).
