Product description:
LOCTITE 315 is a self-shimming thermally conductive, one part adhesive for bonding electrical components to heat sinks with an insulating gap. The high thermal conductivity provides excellent heat dissipation for thermally sensitive components, while the controlled strength permits field and service repair. The self-shimming property produces a consistent 5-6 mil gap between the component and the heat sink. This gap results in electrical insulation while maintaining thermal conductivity. Typical applications include bonding transformers, transistors and other heat generating electronic components to printed circuit board assemblies or heat sinks. In high pot applications this product should be limited to a maximum of 500 volts. Activator 7386 is required for proper curing of Loctite Output adhesives.

LOCTITE 7386 is designed to initiate the cure of Loctite toughened acrylic adhesives. Further information about the product can be obtained from your local technical department: biuro@woronko-loctite.pl

Steps to achieve the best adhesive results:
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 EquipmentEngineers are available to assist you in selecting and implementing the appropriate dispensing equipment for your application.
