New Thermally Conductive Adhesive from Permabond

1 min read

Permabond, who will be exhibiting at the Northern Manufacturing & Electronics show in Manchester on 2nd and 3rd October 2019, is launching ET5441, a new thermally conductive, high temperature resistant, 2 part, room temperature cure epoxy with excellent chemical resistance. ET5441 expands Permabond’s existing thermally conductive adhesives range, which includes UL94-V-0 compliant single part epoxies, toughened acrylics and a flexible modified epoxy adhesive.

ET5441 has been specifically designed to bond metal substrates, when an excellent resistance to high temperature is required, and even retains 6 MPa shear strength at 180°C on steel. It is also suitable for bonding other materials such as ABS, GRP and composite materials. Full cure is achieved in 7 days at room temperature, but it can be accelerated to 24 hours at room temperature followed by 30 minutes at +80°C. Permabond ET5441 provides an excellent resistance to hot and cold water, motor oil, water and glycol.

Its high temperature resistance and thermal conductivity make ET5441 ideal for applications such as:

  • Electric motor magnet bonding
  • Bonding heat sinks to PCBs
  • Applications in vehicle battery packs
  • Bonding parts before e-coating

Permabond will be on stand L51 at Northern Manufacturing & Electronics, at Event City, Manchester. If you are looking for an adhesive, come and visit our stand and we’ll be happy to help you find a solution for your particular application.
