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.
