LOCTITE^® 315 is a 1-part, self-shimming, thermally conductive acrylic adhesive paste. It is activator cured for bonding electrical components with a consistent 5-6 mm (0.2-0.24") gap, so you get electrical insulation as well as high thermal conductivity. This conductivity provides excellent heat dissipation for thermally sensitive components, while the controlled strength permits field and service repair. It’s ideal for bonding transformers, transistors and other heat generating electronic components to printed circuit board assemblies or heat sinks. Use LOCTITE^® 7387 activator for a full cure.
