8331 Silver Conductive Epoxy Adhesive 8331 is an electrically conductive, silver-filled 2-part epoxy adhesive. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates. This product allows for quick, cold-soldering repairs. It can also be used as a solder replacement for bonding heat-sensitive electronic components, or for making conductive connections where soldering is not an option, such as when bonding to glass, soft metals, or plastics. 8331 has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330. For a longer working time, use 8331S.

Storage and Handling Syringe Store between 16 and 27 C in a dry area, away from sunlight (see SDS). To maximize shelf life, recap 1. Twist and remove the cap from the syringe. Do not product firmly when not in use. 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 stop the flow, pull back on the plunger. 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. 2. Measure 1.2 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.
