Epoxies, Etc 40-3901 Electrically Conductive Epoxy Adhesive
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Description: 40-3901 is a two component epoxy adhesive filled with silver. This electrically conductive epoxy resin formulation offers an easy one to one mix ratio that cures at room temperature. 40-3901 is designed for adhesive bonding in microelectronic and optoelectronic applications. Due to its excellent continuity of conductivity, it has also been used extensively in applications such as micro-wave EMI and RFI shielding, in the assembly or repair of printed circuit boards, wave guides, electronic modules, flat cable, high frequency shields, connectors, circuitry, and as a cold solder. 40-3901 is formulated with pure silver (no alloys). Both the resin and hardener have silver particles dispersed.

Features:

  • Electrically conductive
  • Thermally conductive
  • Room temperature cure
  • Easy 1:1 mix ratio
  • Good bond strength
