LOCTITE® ABLESTIK 561K
Features and Benefits
This adhesive film is designed for substrate-attach and heat-sink bonding, and is ideal for bonding materials with severely mismatched coefficients of thermal expansion (CTE).
LOCTITE® ABLESTIK 561K is an electrically insulating, high-strength, film adhesive specially designed for substrate-attach and heat-sink bonding – especially when materials are severely mismatched in terms of coefficient of thermal expansion (CTE). Please note data and results will vary with different thicknesses.
- Flexible for bonding mismatched adherents
- Reworkable
- Thermally conductive
- Electrically insulating film
- Manages applications where CTE mismatch is an issue
- High strength
