40-3909 is a two component epoxy adhesive and coating filled with silver coated nickel. This electrically conductive epoxy resin provides low volume resistivity of less than 5x10^3 ohm-cm. Silver coated nickel offers a lower cost alternative to many silver filled epoxy systems. 40-3909 has a convenient 1:1 mix ratio by weight. It is designed to cure at room temperature overnight but can also be accelerated with mild heat. Due to its excellent electrical continuity and high thermal conductivity, 40-3909 has been used in the assembly or repairs of printed circuit boards, connectors, wave guides, high frequency shields, and as a cold solder.
