Loctite 383 Thermally Conductive Acrylic Adhesive Grey 25ml

• Strength : High
• Viscosity : High
• Color : Grey
• Curing Type : Activator, Room Temperature (Ambient) Cure
• Application : Bonding

 

LOCTITE® 383 is a gray, high strength, high viscosity, thermally conductive, modified acrylic adhesive designed for bonding heat generating components to heat sinks. This product should be limited to a maximum of 500 V in high pot applications. Typical applications include bonding transformers, transistors and other heat generating electronic components to PCB assemblies or heat sinks.

• High strength
• High viscosity
• High thermal conductivity provides excellent heat dissipation for thermally sensitive components
• Controlled strength permits field and service repair

 
383™ 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. The high strength of 383™
provides structural strength to electronic assemblies. 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.
