Silver filled epoxies are traditionally considered the best electrically conductive adhesives on the market. For a more cost effective alternative to pure silver filled epoxy systems, Master Bond developed EP79 and EP79FL. These silver coated nickel filled epoxies feature excellent electrical conductivity. They resist corrosion, are thermally stable and retain their electrical conductivity over extremely long time periods.
EP79FL is a more flexible version of EP79. Its elongation is greater than 60%. This flexiblity makes it particularly useful in bonding dissimilar substrates that are being thermally cycled and shocked. It also enables the cured system to exert very little mechanical stress on sensitive components and substrates.
While both systems offer excellent adhesion, EP79 has higher shear strength properties. In contrast, EP79FL is noted for having higher T-peel strength. Other similarities include their thermal conductivity. They cure at room temperature and have a simple to use 1 to 1 mix ratio by weight or volume. Available in convenient packaging including pre-measured, frozen syringes, they are easy to apply with minimal sagging or dripping, even on vertical surfaces.
EP79 and EP79FL are both used in a wide range of industries: electronics, appliances, automotive, telecommunications, to name a few.
