MG Chemicals Silver Epoxy Adhesive, Extreme Conductivity, 4 hr. working time, 173 g, 2-Part Epoxy Kit

The 8330S Silver Conductive Epoxy Adhesive: Slow Cure/Extreme Conductivity is an electronic grade epoxy that combines long working time and high conductivity with ease of use. It has a convenient 1-to-1 mix ratio and 4–5 hours pot life, which once mixed behaves essentially like a 1-part adhesive for the duration of a work shift. However, unlike 1-part adhesives that often require high heat (130–170 °C), it will cure at 65 °C in less than 2 hours. The cured conductive adhesive bonds very well to most substrates used in electronic assemblies; resists thermal and mechanical shocks; and provides the low resistivity needed for many operating conditions. The 8330S epoxy adhesive forms excellent high conductivity seals, bonds, and traces for electronic devices in automobile, aerospace, marine, communication, and industrial control. The 8330S epoxy has many uses in the production, repair and assembly of electronics in microelectronics and optoelectronics. It has been designed for production environments as a replacement for one part silver conductive epoxy systems when high cure temperatures can potentially damage heat sensitive components, or where frozen storage requirements or shelf life of one part epoxies are a concern. Like all conductive epoxies, it operates as a lead free replacement for metal solder, and it excels at bonding heat-sensitive electronic components. It also provides excellent EMI/RFI shielding and is very effective at filling seems between metal plates.
