COOL BOND® CB7208 EDA2

1 of 13 products in this brand
COOL BOND® CB7208 EDA2 is a modified version of TPT208 designed to have improved bond strength at elevated temperature. CB7208-EDA2 is an aluminum nitride filled, low bond strength thermoplastic film adhesive. It is designed for bonding heat sinks, component, and substrate. CB7208- EDA2 has good thermal conductivity. As applied, it provides >100 psi bond strength that will improve to over 600 psi in-situ over time.

Applications & Uses

Application Area
Applications
  • Component Attach
  • Heat Sink Attach
  • Substrate Attach
Application Process
  • Cut to desired size.
  • Remove one side of releasel liner from adhesive.
  • Place on substrate or component with rolling finger pressure, then remove the other release liner.
  • Place component on substrate with insertion pressure of 10 psi or more. More bond strength will develop in-situ over time during operation.
