Product Description
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.
Optically clear 2K epoxy for encapsulation and embedding — remains transparent after curing. Ideal for decorative bonding, potting, jewelry designs, and see-through applications requiring clarity.

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).
