Reliable thermal management Loctite

Practical benefits

Superior thermal conductivity: You transfer heat away from power transistors and sensitive components directly into the heat sink.
Consistent electrical insulation: The self-shimming formula maintains a uniform gap to deliver dependable electrical isolation between mating surfaces.
Rapid cure without mixing: With the dedicated activator, you achieve fast room-temperature fixturing without needing to pre-mix any components.

In a nutshell

The right choise for

With the Loctite 315 sf 7386 output electronics kit, you mount heat-sensitive electronic components directly to heat sinks or printed circuit boards with ease. This kit includes a 25 ml syringe of Loctite 315 thermally conductive adhesive and an 18 ml bottle of sf 7386 activator. By applying each product to opposite surfaces, the system cures rapidly at room temperature upon assembly without pre-mixing. Its self-shimming technology maintains a consistent 0.12 to 0.15 mm gap to guarantee dependable electrical insulation and efficient heat dissipation across a wide temperature range from -55 °C to +150 °C.
