      MG Silver Conductive Epoxy

MG Chemicals Part Number: 8331-14G


Forms high strength conductive bonds

This two part silver epoxy offers high electrical conductivity and strong conductive bonding. Use in place of traditional soldering on heat sensitive components. Good for repairing defective traces and creating jumpers on boards. Can be used as an effective heat sink adhesive. This Conductive Silver Epoxy comes in two 7g syringes.



This epoxy adhesive can adheres not only on most of the metal surfaces (aluminium, bronze, brass, copper, steel etc.) but it can also well adheres on glass, wood, plastic, paper, fiber & rubber surfaces as well.
