Permabond Europe Launches New Thermally Conductive, High Temperature Resistant Epoxy

ET5441 NewsflashBlog

New Thermally Conductive Epoxy, Permabond ET5441 with High Temperature Resistance!

Permabond® ET5441 is a 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.

Permabond® ET5441 offers high strength performance. Even at 180°C  (356°F) it achieves 5-6MPa (725-870 psi) shear strength on mild steel and can even withstand temperatures above 200°C  for brief periods, making it suitable for applications involving solder reflow processes and paint bake ovens.

Key features of the product include:

  • Full cure at room temperature
  • Excellent thermal conductivity 1 W/m.k (normal epoxies are 0.3 W/m.k)
  • Bonds a wide variety of metals, plastics and composites
  • Long pot life 2-3 hours
  • Packaged in cartridges or bulk, 2:1 mix ratio

Suitable applications include bonding battery cells to casing for electric vehicle batteries, electric motor and electronics components. Applications where high strength structural bonding and resistance to high temperatures are required but where a single-part, heat-cure epoxy is impractical.

Available in 10 x 50ml cartridges, 6 x 400ml cartridges, 5 litre bulk packaging. The shelf life of ET5441 is 12 months when stored at 5-25°C (41-77°F).
