8329TCS High Thermal Conductivity Adhesive 8329TCS is a 2-part, heat-cure, thermally conductive epoxy adhesive with a 4-hour working time. It is a dark grey, smooth, thixotropic paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. This thermal adhesive is used to glue heat sinks to LEDs, CPUs and other heat-generating components. 8329TCS has been designed for maximum thermal conductivity. It is highly viscous and must be mixed by hand prior to application. For a lower viscosity, use 8329TFS. For a shorter working time, use 8329TCM.

Sto re b et ween 16 and 27 C in a dr y area, away f ro m sunlight (see SDS). To maximize shelf life, recap Syringe pro duc t fi r mly w hen not in use. 1. Twist and remove the cap from the syringe. Do not discard cap. 2. Measure 1 part by volume of A. 3. Measure 1 part by volume of B. 4. Dispense material on a mixing surface or container, and thoroughly mix parts A and B together. 5. To sto p t he fl ow, pull bac k o n t he plung er. 6. Clean nozzle to prevent contamination and material buildup. 7. Replace the cap on the syringe. Can or Jar 1. Stir each part individually to re-incorporate material that may have separated during storage. 2. Measure 0.95 part by weight of A. 3. Measure 1 part by weight of B. 4. Thoroughly mix parts A and B together. 5. Apply adhesive to the application area. Disclaimer T his info r mat i o n is b e l i eve d to b e ac c ur ate.
