Description Product Technical Specs Typical Applications

For electronic applications that require shielding of electromagnetic interference (EMI), an EMI-conductive sealant may be a solution. Used in electronics-based applications, an electrically conductive silicone RTV (room temperature vulcanizing), such as EX3-301, is a one-part electrically conductive paste. At room temperature, the electrically conductive silicone adhesive has a work time of 15 minutes, a tack-free time of 60 minutes and a cure time of 72 hours. The dark-gray electrically conductive RTV sealant is a condensation cure, using the moisture from the ambient environment, and works through an oxime-neutral cure system. With a wide operating temperature range of -45 to 260ºC, it is high-temperature resistant as well as noncorrosive. The thermal conductivity of EX3-301 is 2.5 W/mK, curing to a tensile strength of 300 PSI. The conductivity of the sealant is provided by a 98.00% solids formulation of nickel graphite.
