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

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.
