MG Chemicals 8329TCM - Thermal Adhesive, High TC
8329TCM is a 2-part thermally conductive epoxy adhesive. It is a dark gray, smooth, thixotropic paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. This adhesive is most often used as heatsink glue, attaching heatsinks to CPUs, LEDs, or other heat generating electronics components. This compound has been formulated for high thermal conductivity. It is highly viscous and must be mixed by hand prior to application. For a lower viscosity use 8349TFM. For a shorter working time, use 8349TFM. For a longer working time, use 8329TCS.
