Master Bond's flexibilized epoxy combines high strength with chemical and abrasion resistance
Master Bond introduced its Polymer System EP30D-7, a two component epoxy designed for bonding, sealing, coating, and encapsulating applications in the electronic, electrical, computer, metalworking, optical, electro-optical and oil/chemical processing industries. Its lower exotherm also makes it suitable for casting and potting in cross section thicknesses of over one inch.
Serviceable over a temperature range of -100ºF to above +250ºF, EP30D-7 is designed to cure at room temperature or more rapidly at elevated temperatures with minimal shrinkage. This system is 100% reactive and contains no solvents or diluents. The cured elastomer is also electrical insulator, resists thermal cycling and is chemical resistant to water, fuels, and inorganic solvents. EP30D-7 has a tensile strength greater than 1,600 psi, a Shore A hardness of 90, an elongation of more than 40% and a dielectric constant exceeding 400 volts/mil.
