LOCTITE® 384 is a white to off-white, 1-part, thermally conductive, modified acrylic paste adhesive designed for bonding heat generating components to heat sinks. The high thermal conductivity provides excellent heat dissipation for thermally sensitive components, while the controlled strength permits field and service repair. It should be limited to a maximum of 500 V in high pot applications.

• Thermally conductive
• Controlled strength permits field and service repairs
• Used in bonding transformers, transistors and other heat generating electronic components

 
LOCTITE 384 is a thermally conductive adhesive system
designed for bonding heat generating components to heat
sinks. The high thermal conductivity provides excellent heat
dissipation for thermally sensitive components, while the
controlled strength permits field and service repair. In high pot
applications this product should be limited to a maximum of
500 volts. Typical applications include bonding transformers,
transistors and other heat generating electronic components to
printed circuit board assemblies or heat sinks.

Thermal Cycle Resistance

Bonded aluminum to epoxyglass lapshears cured 72 hours
using Activator 7387™ on 1 side were subjected to thermal
cycling of 15°C to 100°C with a ramp time of 30 minutes. No
loss in strength occurred after 1,000 hours of cycle time.

GENERAL INFORMATION

For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).

Directions for use:

1. For best performance bond surfaces should be clean and
   free from grease.
2. Use applicator to apply the activator to the surface to be
   bonded.
3. After the solvent evaporates, the active ingredients will
   appear wet, and will remain active for up to 2 hours after
   application. Contamination of the surface before bonding
   should be prevented.
4. Apply adhesive to the unactivated surface.
5. Secure the assembly, and wait for the adhesive to fixture
   (approximately 5 minutes) before any further handling.
   Full cure occurs in 4 - 24 hours.
6. The amount of adhesive applied to the part or heat sink
   should be limited to the amount necessary to fill the bond
   and just enough to give a small fillet.
7. The dispensing or application of the adhesive should be
   done as to minimize air entrapment within the bondline.
8. The successful application of this product depends on
   accurate dispensing on the parts to be bonded. Loctite
   Equipment Engineers are available to assist you in
   selecting and implementing the appropriate dispensing
   equipment for your application.

Device Removal/Repair

Components or devices bonded with LOCTITE 384 can be removed
while hot using heat from a hot air jet. Bond strength decreases at
approximately 65 °C to 93 °C allowing components to be removed with
lower shear forces. Method of removal/repair should be specifically
determined due to the variety of components or devices bonding
behavior.
