PERMABOND ET 5411
PERMABOND ET 5411
Permabond · Permabond Engineering Adhesives Ltd ·

Permabond ET5411 is a high-temperature resistant 2K epoxy in a 2:1 ratio — low viscosity for tightly toleranced structural bonding under thermal stress.

ET5411 was specifically developed for applications with elevated continuous temperatures — where standard epoxies would lose strength, ET5411 remains resilient. Its low viscosity allows it to penetrate tight-tolerance adhesive gaps.

HIGH-TEMPERATURE EPOXY

High-temperature, low-viscosity, two-component epoxy – designed for structural bonding under heat stress and with tightly toleranced gaps. Retains strength at elevated continuous temperatures.

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 the mixing nozzle and press evenly (2:1 volume ratio 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 is typically achieved after 24 hours 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
Before bonding, degrease and, if necessary, sand the surfaces. Heat curing can further increase strength.
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 ET 5411

Practical application and design questions — answered by SILITECH.

High-temperature 2-component epoxy 2:1 — low viscosity for tightly toleranced structural bonding under heat stress. 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 ET 5411 is typically — at 23 °C. Higher temperatures shorten, lower temperatures lengthen the pot life. Mixtures above approximately 100 g may gel more quickly due to an exothermic reaction.

Permabond ET 5411 typically bonds metals, composites, and plastics. For substrate-specific values, see TDS.

Permabond ET 5411 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 ET 5411 is a high-temperature, two-component epoxy resin (2:1 volume mix, pot life) — low viscosity, heat Permabond ET 5441 is thermally conductive UL94 (2:1 volume mix, pot life) — thermally conductive, flame-retardant.

From the Permabond 2K epoxy range, select according to application, mixing ratio, and strength requirements: Permabond ET 5411 (High-temperature 2K epoxy 2:1 — low viscosity, heat-resistant); Permabond ET 5441 (Thermally conductive UL94); Permabond ET 5401 (Fast 2:1); Permabond ET 540 (Long pot life). For aerospace applications, see ET 515 (Aircraft Seat Trays); for food applications, see ET 5162 (EU 10/2011 + FDA); for thermal conductivity/fire protection, see ET 5441 (UL94-V0).
