8331S Silver Conductive Epoxy Adhesive 8331S is an electrically conductive, silver-filled 2-part epoxy adhesive with a long working time. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates. It can 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. 8331S has been formulated to be economical. For a higher fill version that maximizes conductivity, use 8330S. For a shorter working time and room temperature cure, use 8331.

(downloadable at www.mgchemicals.com). Cure the adhesive in an oven at one of these time/temperature options: Recommended Preparation 2 h 65 C 1 h 80 C Clean the substrate with Isopropyl Alcohol, MG 824, 30 min 100 C so the surface is free of oils, dust, and other residues. Storage and Handling Syringe Store between 16 and 27 C in a dry area, away from 1. Twist and remove the cap from the syringe. Do not sunlight (see SDS). To maximize shelf life, recap discard cap. product firmly when not in use. 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 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.
