Nickel Filled Electrically Conductive - Adhesives, Sealants and Coatings

Master Bond offers a wide variety of nickel filled electrically conductive adhesives. Both one and two component systems are available for use. These compounds provide a more cost effective solution than silver filled grades for applications that require electrical conductivity and low volume resistivity. They also have outstanding resistance to water and chemicals.

The superior performance profile of our electrically conductive compounds is widely recognized throughout the electronics industry. 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. Special grades are vibration and shock resistant, cryogenically serviceable, “snap curing”, offer exceptional peel and shear strength and are screen printable.

Master Bond Polymer Adhesive EP76M

Master Bond Polymer System EP76M is a two component, nickel filled, electrically conductive adhesive for high performance bonding, sealing, and coating formulated to cure at room temperature or more rapidly at elevated temperatures. Unlike the majority of two part nickel conductive systems, EP76M has a one-to-one mix ratio by weight or volume. It readily develops a high bonding strength of more than 2000 psi tensile shear strength when measured and cured at 75°F. It is 100% reactive and does not contain any diluents or solvents. The volume resistivity of the cured system is 5-10 ohm-cm.

Master Bond Polymer System EP76M can be applied with minimal sagging or dripping even on vertical surfaces, although it can be made thinner (flowable) by adding 5 to 10% of an appropriate solvent (xylene, acetone, MEK, etc.) by weight. The high strength bonds are remarkably adaptable to thermal cycling and resistant to chemicals including water, oil and most organic solvents over the exceptionally wide temperature range of -60°F to more than +250°F. Adhesion to metals, glass, ceramics, vulcanized rubbers and many plastics is excellent. Parts A and B are both colored gray. Master Bond EP76M adhesive is widely used in the electronic, electrical, computer, semiconductor, microwave, appliance and automotive industries among others. There are also are a number of specialized versions of EP76M available. These include EP76 which meets certain military specs, EP76M-F which is a fast curing version (5-10 minute set up time), and EP76MHT which is a high temperature resistant version (serviceable up to 400°F).

Packaging

Our electrically conductive products consist of one and two part epoxies. They are conveniently packaged for ease of use. They are available in syringes, jars, bubble packs, cartridges, etc. Two component systems can be purchased in premixed, frozen syringes. Freshly prepared to maximize shelf life, Master Bond electrically conductive compounds can be bought in quantities from grams to gallons.
