- Description
- Technical specification
When you’re working with applications where CTE mismatch is an issue, try LOCTITE® ABLESTIK 561K. This film adhesive is electrically insulating, high strength, and specially designed for substrate attach and heat sink bonding – especially when materials are severely mismatched in terms of coefficients of thermal expansion. Please note data and results will vary with different thicknesses.
