MG Chemicals 8329TFF - Fast Cure Thermal Adhesive

Chemical Family: Epoxy & Epoxy Derivatives

8329TFF is a 2-part, flame retardant, thermally conductive epoxy adhesive with a 5-minute working time. It is an off white, smooth, thixotropic paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. This thermal glue is often used to bond heatsinks to CPUs, LEDs and other electronics components. This product has a very short working time. For a longer working time, use 8349TFM or 8329TFS.
