This thermal adhesive is a 2-part 1-1 epoxy system. It is a smooth, dark, off-grey paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. It meets UL 94V-0 Standard as flame retardant. It bonds well to metals, ceramics, glass, and most plastics used in electronic assemblies.

This thermal adhesive is most often used to bond heatsinks to CPUs, LEDs, and other electronic components, but is also suitable in many other applications that require a thermally conductive electrically insulating adhesive.

This thermal glue has a 20-minute working time. We also offer a faster-setting alternative with a 5-minute working time (8329TFF), a heat cure alternative with a 4-hour working time (8329TFS), and a heat cure 1-part alternative with an unlimited working time (9460TC). A silver-filled electrically conductive version and thermal pastes are also available.
