Material Notes:
Description: Master Bond Polymer System EP37-3FLFAN is a two component system for high performance potting, bonding, sealing and coating that is 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 exceptionally 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. EP37-3FLFAN 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. Part A is light gray and Part B is gray in color. Master Bond EP37-3FLFAN is widely used in the electronic, electrical, computer, metalworking, aerospace and chemical industries where electrical insulation and good heat transfer are required. The attractiveness of EP37-3FLFAN lies in the fact that this thermally conductive system retains a high level of flexibility while having the desirable physical characteristics inherent in epoxies. Product Advantages: Convenient mixing: easy-to-use, non-critical one to one mix ratio by weight or volume. Long working life; cures readily at room temperature and can be accelerated by heat. Good thermal conductivity with excellent electrical insulation properties. High bond strength to a wide variety of substrates; very good adhesive properties. Low viscosity with excellent flowability; ideal for potting and casting. Outstanding flexibility; resists rigorous thermal cycling, mechanical and thermal shocks. Good overall physical strength properties and chemical resistance. Cryogenically serviceable down to 4K.Information provided by MasterBond®
