The MG Chemicals 8330S-21G is a mixture of two syringes of 21 grams of silver extreme conductivity epoxy with a quick drying and working time in 4 hours.
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.
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.
- Excellent 0.0007 Ω·cm electrical resistivity and 1.75 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
- Optimal cure temperature of only 65 °C—lower than most 1-part epoxies and suitable for use on heat sensitive componentsStores and ships at room temperature—no freezing or dry ice required
- 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
- Room temperature cure is possible (96 hours)
- Excellent adhesion to most electronic substrates
