Master Bond, Inc. Two Component, Silver Coated, Nickel Filled Epoxy EP79

Master Bond Polymer System EP79 is a two component, silver coated nickel filled, electrically conductive adhesive for high performance bonding and sealing formulated to cure at room temperature or more rapidly at elevated temperatures. EP79 offers a convenient one-to-one mix ratio by weight or volume. It readily develops a high bonding strength of more than 1800 psi tensile shear and a T-peel of greater than 20 pli 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 very low - less than 0.04 ohm-cm. Master Bond Polymer System EP79 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 4K to +275°F, enabling it to be serviceable even in cryogenic applications. Adhesion to metals, glass, ceramics, vulcanized rubbers and many plastics is excellent. Parts A and B are both colored gray. Master Bond EP79 adhesive is widely used in the electronic, electrical, computer, semiconductor, microwave, appliance, and automotive industries, among others. For convenient handling, EP79 is now available in premixed and frozen syringes.
