8329TCM Technical Data Sheet Thermally Conductive Epoxy Adhesive Description 8329TCM is a thermally conductive two-part epoxy adhesive. It is dark grey, smooth, viscous, 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. 8329TCM has been designed for maximum thermal conductivity with a high viscosity. For a lower viscosity, use 8329TFM. For a faster working life, use 8329TCF. For a longer working life, use 8329TCS. Features and Benefits Thermal conductivity: 1.4 W/(mK) 1:1 mix ratio Working life: 45 minutes Cure time: 24 hours room temperature or 1 hour at 65 C (149 F) Provides strong electrical insulation High tensile and compressive strength Strong resistance to humidity, salt water, mild bases, and aliphatic hydrocarbons Shelf life: 3 years RoHS 3 compliant Page 1 ISO 9001:2008 Registered Quality System.
