MG Chemicals 9460TC - Thermally Conductive 1-Part Epoxy Adhesive

9460TC is a 1-part, heat cured only, thermally conductive epoxy adhesive with an unlimited working time. It is an off-white, smooth, thixotropic paste that cures to form a hard, durable polymer that is thermally conductive, yet electrically insulating. This 1-part adhesive is used to glue heat sinks to LEDs, CPUs and other heat-generating components. It does not require mixing and is suitable for use with manual, pneumatic, and automatic dispensing systems.

Recommended Preparation

Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues.

Syringe

  1. Twist and remove the cap from the syringe. Do not discard cap.
  2. Dispense the adhesive evenly to both surfaces.
  3. To stop the flow, pull back on the plunger.
  4. Clean nozzle to prevent contamination and material buildup.
  5. Re-place the cap on the cartridge or syringe.
