Master Bond’s line of electrically conductive adhesives is the number one choice for the design of tomorrow’s advanced electrical circuitry. Nobody offers more choices or solutions. The Master Bond product line includes silver, nickel, copper and graphite-filled compounds. Master Bond even offer silver-coated nickel systems for low resistance where cost-effectiveness is crucial. Specific compounds are designed to cure at ambient temperatures or upon brief exposure to elevated temperatures. The cured products offer high physical strength, superior substrate adhesion and uniform electrical conductivity even upon exposure to hostile environmental conditions. Long-term durability is excellent.
