Introduction
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.

Popular Electrically Conductive Nickel Polymer Systems
Some of the popular electrically conductive nickel polymer systems
include:
EP76M
Master
Bond's 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. Adaptable to
thermal cycling and resistant to many chemicals.
EP21TDCNFL
EP21TDCNFL is a two component, nickel filled, electrically
conductive system with high flexibility and elongation. Serviceable over wide
temperature range of 4K to +250°F.
Supreme 10HTFN
Supreme
10HTFN is a one component, no mix, nickel conductive system with high shear
and peel strength. Cures in as little as 2 minutes at 380 -400°F. Superior
resistance to impact, thermal shock, vibration and stress fatigue cracking.
Serviceable from 4K to 400° F.
X5N
X5N is a
cost effective, one component nickel conductive elastomer adhesive, sealant and
coating for EMl/RFI shielding. Superior shielding over a wide frequency range
and excellent environmental resistance.

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.
