Combining the benefits of epoxy resins and polyurethanes, Master Bond Polymer System EP30D-7 offers superior strength, flexibility, abrasion resistance and toughness. This two component epoxy is ideal for high performance 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 ideal for casting and potting in cross section thicknesses of over one inch.
Serviceable over the wide 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 an excellent electrical insulator. It also resists thermal cycling well and stands up to a variety of chemicals.
EP30D-7 has an impressive tensile strength of 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. It is resistant to thermal cycling and chemicals including water, fuels, and inorganic solvents even at high temperatures. It is available for use in pint, quart, gallon, and 5 gallon containers kits.
