8331S
Technical Data Sheet
Silver Conductive Epoxy Adhesive
Description
8331S is an electrically conductive, silver-lfi led two-part epoxy adhesive with a long working life. 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 life and room temperature cure, use 8331.
