Product Description
Permabond ET5441 is a thermally conductive, two-component epoxy adhesive for bonding metals at elevated temperatures. Its thixotropic consistency facilitates application on vertical surfaces.

| Complete curing | 7 days at 23 °C or 2 hours at 80 °C |
| Maximum gap filling | 2 mm |
| Thermal conductivity | 1.1 W/(m·K), ISO 8302 |
| Tensile shear strength on steel | 20–25 N/mm² |
| Hardness | Shore D 85–95, ISO 868 |
Processing and interpretation
Clean the bonding surfaces and mix the material evenly in the specified ratio. The curing time depends on the actual temperature of the bond. Do not subject the joint to any load until it has sufficiently cured.
The strength at high temperatures must be determined based on the manufacturer's curve and the intended load duration. A measurement taken after brief temperature conditioning does not represent the continuous operating temperature.
Fire behavior and handling
The manufacturer describes ET5441 as formulated to meet UL94 HB specifications. Requirements for the finished component must be verified separately. Refer to the safety data sheets for both components before processing.
