PERMABOND® ET5441 – Two-Part Epoxy

PERMABOND® ET5441 is a thixotropic, thermally conductive two-component adhesive based on epoxy resin. It is specifically designed to bond metal substrates when excellent resistance to high temperature is required. The full cure is achieved in 7 days at room temperature, but it can be obtained in 24 hours at room temperature followed by 30 minutes at +80°C (176°F). Permabond ET5441 provides excellent resistance to motor oil, glycol and hot and cold water.
Permabond ET5441 has been specifically formulated to meet the requirements of:
• Flammability rating UL94 HB
• Thermal vacuum outgassing test for the screening of space material ECSS-Q-ST-70-02
