Master Bond unveils Polymer System EP30D-7 flexibilized epoxy

SEPTEMBER 8, 2010 -- Combining the benefits of epoxy resins and polyurethanes, Master Bond Polymer System EP30D-7 offers superior strength, flexibility, abrasion resistance and toughness, Master Bon asserts. This two-component epoxy is designed 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 suitable for casting and potting in cross section thicknesses of over 1 inch, Master Bond adds.

Serviceable over the 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. The system is 100% reactive and contains no solvents or diluents. The cured elastomer is an excellent electrical insulator, says Master Bond. It also resists thermal cycling well and stands up to a variety of chemicals.

EP30D-7 has a 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 V/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.
