- 4-Hour 74 deg C Cure
- Two-Hour Working Window
Product Description
LOCTITE® ABLESTIK 369-3 is a silver-filled, electrically conductive epoxy adhesive for die-attach and general-purpose bonding applications. The polyamine-activated system provides a two-hour work life at 25°C and uses a moderate-temperature guideline cure of 4 hours at 74°C. Typical cured properties include volume resistivity of 0.0005 ohm-cm, Shore D hardness of 80, and aluminum-to-aluminum lap shear strength of 7.6 N/mm² at 25°C.
Key features
- Electrically conductive: Typical cured volume resistivity is 0.0005 ohm-cm.
- Moderate-temperature cure: Guideline cure schedule of 4 hours at 74°C.
- Extended processing window: A two-hour work life at 25°C supports adhesive placement before cure.
Applications / Suitable for
- Die-attach applications
- General-purpose conductive bonding
- Aluminum-to-aluminum bonding under the documented test condition
