8329TCS Technical Data Sheet Thermally Conductive Epoxy Adhesive Description 8329TCS is a thermally conductive two-part epoxy adhesive with a long working life. 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. 8329TCS has been designed for maximum thermal conductivity with a high viscosity. For a lower viscosity, use 8329TFS. For a shorter working life, use 8329TCF or 8329TCM. Features and Benefits Thermal conductivity of 1.4 W/(mK) 1:1 mix ratio Working life: 4 hours Cure time: 1 hour at 80 C (176 F) Provides strong electrical insulation High tensile strength Strong resistance to humidity, salt water, mild bases, and aliphatic hydrocarbons Shelf life: 3 years RoHS 3 compliant NASA low outgassing approved Page 1 ISO 9001:2008 Registered Quality System.
