MG Chemicals 9400 - 1 Part Epoxy, Electrically Conductive Adhesive, Low Tg

9400 is an electrically conductive, silver-filled, 1-part epoxy adhesive with a low cure temperature. It is smooth, thixotropic, non-sagging, and bonds well to a wide variety of substances. It has an unlimited working life at room temperature. This product can create electrically conductive bonds where soldering is not an option, such as when bonding to heat-sensitive components, glass, soft metals, or conductive polymers. It also works well in semi-conductor packaging, microelectronic attachment and lid-sealing, and as a die attach for small chips, LEDs and diodes. It does not require mixing and can be readily used in manual, pneumatic and robotic dispensing processes. 9400 has been formulated to have a low Tg, which allows for minimal stress on substrates during temperature changes. For a higher Tg, use 9410.

Cure Method
Recommended Preparation

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

Syringe or Cartridge

  • Twist and remove the cap from the cartridge or syringe. Do not discard cap.
  • Dispense the adhesive evenly to both surfaces.
    • For 30 mL size, insert the cartridge in the 8DG-30-1 dispensing gun (see Dispensing Accessories Application Guide).
  • To stop the flow, pull back on the plunger.
  • Clean nozzle to prevent contamination and material buildup.
  • Replace the cap on the cartridge or syringe.
