MG Chemicals 8349TFM - Thermal Adhesive
- Chemical Family
- Epoxy & Epoxy Derivatives
Thermal Adhesive 8349TFM is a 2-part, flame retardant, thermally conductive epoxy adhesives. It is a dark gray, smooth, thixotropic paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. This thermal adhesive is most often used to bond heatsinks to CPUs, LEDs and other electronics components. For a shorter working time, use 8329TFF. For a longer working time, use 8329TFS.

- Syringe or Cartridge
1. Twist and remove the cap from the syringe or cartridge. Do not discard cap. 2. Dispense a small amount to ensure even flow of both parts. A manual or pneumatic dispensing gun is required for a 50 mL cartridge. 3. (Optional) Attach a static mixer. a. Dispense and discard 3 to 5 mL of the product to ensure a homogeneous mixture. b. After use, dispose of static mixer. 4. Without a static mixer, dispense material on a mixing surface or container, and thoroughly mix parts A and B together. 5. To stop the flow, pull back on the plunger. 6. Clean nozzle to prevent contamination and material buildup. 7. Re-place the cap on the syringe or cartridge.
- Dispensing Accessories
Consult the table below for accessory selection. See the Dispensing Accessories Application Guide for usage instructions. 8MT-50-FT should only be used with a pneumatic dispenser.
