Permabond ET505 is a clear 2K epoxy in a simple 1:1 mixing ratio — a universal adhesive for visible bonding with a subtle amber-colored appearance.

ET505 is the simple 1:1 volume variant of a clear-curing epoxy — the amber component provides a warm, subtle color. Suitable for universal bonding applications with a visible adhesive bead.

APPLICATION PROFILE

Clear 2-component epoxy in a 1:1 ratio with amber-colored hardener — for visible bonds with a subtle color. Universal application on metal, wood, ceramics, and composite materials.

Service work
When 1:1 processing is required.

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 dual cartridges: Attach the mixing nozzle and press evenly (1:1 volume mixing ratio). For larger containers: Weigh out the resin and hardener in the correct ratio and mix thoroughly until no streaks are visible. Avoid air bubbles.
3
Apply adhesive + join components
Apply the mixed adhesive to a bonding surface within the pot life (—). Join the components with sufficient pressure to ensure the adhesive is distributed over the entire bonding surface.
4
Fix components in place during curing
Use a clamping device or vise to prevent the components from moving during curing. Wait for handling strength and functional strength to be determined according to the TDS (Technical Data Sheet).
5
Full curing at room temperature
Final strength is typically achieved at 23 °C. Increasing the temperature by 8 °C halves the curing time; lower temperatures slow down the process. If required, optional post-curing at 60–80 °C for maximum strength.

Frequently asked questions about Permabond ET505

Practical application and design questions — answered by SILITECH.

Clear 2-component epoxy 1:1 — amber-colored hardener for visible bonds. The 2-component epoxy is mixed in a 1:1 volume ratio and offers a pot life of —.

Mix both components in a 1:1 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 ET505 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 ET505 typically bonds metals, composites, and plastics. For substrate-specific values, see the TDS.

Permabond ET505 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 ET505 is a clear, amber-tinted, two-component epoxy for visible bonding (1:1 volume mix, pot life). Permabond ET5011 is optically clear (100:94, pot life) and completely transparent.

From the Permabond 2K epoxy range, select according to application, mixing ratio, and strength requirements: Permabond ET505 (Clear 2K epoxy with amber tint — for visible bonding); Permabond ET5011 (Optically clear); Permabond ET500 (Fast-curing epoxy); Permabond ET514 (High strength). 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).
