MG Chemicals 8331D Silver Conductive Epoxy 14gm

This is a two-part, smooth, silver paste that cures to form a hard, durable polymer that is highly conductive, 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 10 minute working time. It achieves an operational cure in five hours at room temperature and full cure in a day. At 65°C, it cures in only 15 minutes.

Good 0.017 Ω·cm electrical resistivity and 0.90 W/(m·K) thermal conductivity
Adheres to most electronic substrates
Stores and ships at room temperature—no freezing or dry ice required
Very long shelf life of at least two years—even when stored at room temperature
Easy 1:1 mix ratio
Strong water and chemical resistance to brine, acids, bases, and aliphatic hydrocarbons

The 8331 can be 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, plastics or soft metals. 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 especially useful in repairing rear window defrosters on automobiles.
Its primary applications are in the repair and 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.
