Master Bond’s Polymer System EP30D-7 Combines High Strength and Toughness with Chemical and Abrasion Resistance

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 1in.

Serviceable over the wide temperature range of -100°F to above +250°F, 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 400v/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 5gal container kits.
