EP37-3FLFAO Product Description

Master Bond EP37 3FLFAO is a two component system for high performance potting, bonding, sealing and coating formulated to cure at room temperature or more rapidly at elevated temperatures. It has a convenient one to one mix ratio by weight or volume. It has an unusual blend of properties including high thermal conductivity, excellent electrical insulation properties, good physical strength and a high degree of flexibility. This system forms tough bonds that are resistant to shock, impact and thermal cycling as well as chemicals including water, oil and many solvents. EP37 3FLFAO has low viscosity with excellent flow characteristics making it ideal as a thermally conductive potting epoxy. It is cryogenically serviceable over the wide temperature range of 4K to 250°F. Parts A and B are off white in color. Master Bond EP37 3FLFAO is widely used in the electronic, electrical, computer, metalworking, aerospace and chemical industries where electrical insulation and heat transfer are required. The uniqueness of EP37 3FLFAO lies in the fact that this thermally conductive system retains a high level of flexibility while having the desirable physical characteristics inherent in epoxies. EP37-3FLFAO has been certified by NASA as a low outgassing epoxy.
