MG Chemicals 8331S Silver Epoxy Adhesive - High Conductivity, 4 hr. Working time, 15 g, 2 Dispeners (8331S-15G)
This is a two-part, smooth, silver paste that cures to form a hard, durable polymer that is highly conductive, both electrically and thermally. It adheres strongly to metals, glass, and well to most plastics used in electronic assemblies. It has a convenient 1-to-1 ratio, and a long 4 hour working time. Heat is required for proper cure ( 2 hours at 65°C) The mixed adhesive essentially acts like a 1-part adhesive for 4 hours. Unlike 1-part adhesives, however, it does not require high curing temperatures or frozen storage, and it has a very long shelf life. Applications and uses: The 8331S is used as a solder replacement for bonding heat-sensitive electronic components and for making conductive bonds where solder is not an option, such as when bonding to glass, soft metals or plastics. It allows for quick cold soldering repairs of electronic devices, makes excellent thermal connections, provides excellent EMI/RFI shielding, and is very effective at filling in seams between metal plates. It is useful in applications where the high cure temperatures of 1 part epoxy systems can potentially damage components. Its primary applications are in assembly of electronic devices. It is used in the automobile, aerospace, marine, communication, instrumentation, and industrial control equipment industries, and is widely used by hobbyists and makers.
