Material Notes:
TRA-DUCT 2979 is a fast curing one-part epoxy adhesive with superior electrical conductivity and bonding capability. It has been shown to retain these properties through hundreds of hours of rapid temperature cycling (-40 to 150°C). It also has superior impact absorption and stress resistance. These qualities make it an excellent choice for a number of electronic applications especially in "under the hood" and other harsh operating environments. TRA-DUCT 2979 has a shelf life of at least 6 months when stored at -40°C. It contains no volatile, harmful solvents or lead, and conforms to all of the requirements of the solder replacement market.Information provided by Tra-Con Inc.
