This heatsink adhesive paste is a 2-part, 1-1 epoxy system. It is a smooth, dark grey paste that cures to form a hard, durable, thermally conductive polymer. It provides strong electrical insulation and excellent protection from humidity, salt water, mild bases, and aliphatic hydrocarbons. It bonds well to metals, ceramics, glass, and most plastics used in electronic assemblies.

This thermal adhesive paste is most often used to attach heatsinks to CPUs, LEDs, or other heat generating electronic components. It is also suitable in many other applications that require a thermally conductive electrically insulating bond.

This compound has been formulated for high thermal conductivity. It is highly viscous and must be mixed by hand prior to application.
