Loctite 5404 Technical Data Sheet

For bonding circuit board substrates, metallic heat sinks, and ceramic chips, Loctite is an ideal selection for an adhesive. Once the material has been removed, it should not be returned to its original container as contamination may occur.

Repacking Pails into Semco Cartridges December 4, Fluxing of Solar Panel Interconnects November 30, Loctite Thermally Conductive Silicone Adhesive For bonding circuit board substrates, metallic heat 54404, and ceramic chips, Loctite is an ideal selection for an adhesive.


When applying or dispensing this material, a method that eliminates air entrapment within the bond line should be used. The proper cure rate depends heavily on the composition, size, and geometry of the parts that are being bonded, as well as the type of oven that is being used. Loctite provides strong bonds for metal enclosures in electronics circuits as well as modules, power semiconductors, graphics processors and other heat generating devices to their heat sinks.

This product boosts shock lodtite and load bearing characteristics of the bond area, and has low resistance to the stream of heat that moves from power device to heat sink. An adhesive bond line of.

Loctite Adhesive is a white to gray silicone adhesive paste designed to bond power devices to their respective heat sinks. For additional assistance with Loctite Silicone Adhesive, please contact Kraydenan authorized distributor of Henkel Loctite Adhesives.

This product offers low resistance to the flow of heat from the power device to the heat sink. This, in turn, helps the conductive filler maintain consistent dispersion within the adhesive matrix. These suggested times exclude heat up rate. It is vital that the bond lines reach these temperatures for their specified times.


The specific gravity of Loctite Adhesive is 2. This silicone based adhesive was designed for applications that include bonding numerous different types of devices that generate heat to their corresponding heat sinks. This material combines high thermal conductivity and great electrical isolation. The dielectric breakdown strength is For additional technical data, please see the Loctite Technical Data Sheet.
