Details
MG Chemicals 8330S Silver Epoxy Adhesive, Extreme Conductivity, 4 hr. Working time, 21 g, 2 Dispeners (8330S-21G)

Excellent 0.0007 Ω·cm electrical resistivity and 2.4 W/(m·K) thermal conductivity
Easy 1:1 mix ratio and long working time may be mixed once and then used as a 1-part epoxy for a four hour production shift
Heat Cure is Required. Cure temperature of only 65 °C for 2 hours —lower than most 1-part epoxies and suitable for use on heat sensitive components.
Very long shelf life of at least two years even when stored at room temperature
Strong water and chemical resistance to brine, acids, bases, and aliphatic hydrocarbons
MG Chemicals 8330S Silver Conductive Epoxy Adhesive with two 7 gram syringes, 3 milliliters each. 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 to 170 degree C), it will cure at 65 degree 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. RoHS and REACH compliant. Warranty on this product for 12 months from the date of purchase by the end user. Constant service temperature: -40 degree C to 150 degree C (-40 degree F to 302 degree F).
