EP40 is a flexible, two-component epoxy resin compound developed to offer outstanding shear and peel strength and is especially designed for bonding, sealing and casting engineering plastics and metals. This compound is formulated to cure readily at ambient or more quickly at elevated temperatures with a convenient, non-critical one-to-one mix ratio, weight or volume. The company says EP40 has been found to provide a solution for applications requiring the strength properties of epoxy resins along with enhanced flexibility and peel strength characteristics. Performance characteristics include resistance to thermal cycling as well as mechanical vibration and shock.

Low viscosity facilitates bonding, sealing, casting, and other processing operations. The availability of versatile cure schedules further simplifies the application. It offers adhesion to a variety of substrates, from engineering plastics such as polycarbonates, acrylics and ABS to steel, aluminum and other metals. Shear and peel strength for bonding polycarbonates are in the order of 1,000 pounds per square inch (psi) and 20 pli respectively, while steel and aluminum bonds yield shear strength values as high as 1,800 and 1,500 psi. The resin compound has a wide service temperature range of -100 degree fahrenheit to +230 degree fahrenheit (-73.3 degree celcius to +110 degree celcius). Master Bond, Inc.,
