MG Chemicals 8329TFM - Thermal Adhesive, Flowable
- Chemical Family
- Epoxy & Epoxy Derivatives
8329TFM is a thermally conductive two-part epoxy adhesive. It is dark gray, smooth, thixotropic, and bonds well to a wide variety of substrates. This product is used to bond heat sinks, LEDs, and other heat-generating components in electronic assemblies. It is suitable for use with dual-syringes, mix-tips, and automatic dispensing systems. For a faster working life, use 8329TFF. For a longer working life, use 8329TFS.
