MG Chemicals Silver Conductive Epoxy, 8331S-15G, Syringe, 15 g, slow cure, forms high strength conductive bonds.
The 8331S Silver Conductive Epoxy Adhesive: Slow Cure is an economical electronic grade epoxy that combines long working time and good conductivity with ease of use. It has a convenient 1-to-1 mix ratio and 45 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 (130170 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 8331S epoxy adhesive is great for forming conductivity seals, bonding, and repairing of electronic devices. Good 0.0060 cm electrical resistivity and 0.95 W/(mK) thermal conductivity Easy 1:1 mix ratio and long working timemay 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 components Stores 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
