Master Bond Polymer System EP30DP is a versatile, two component, epoxy-urethane elastomeric compound, featuring superior strength, toughness, and abrasion resistance for high performance bonding, sealing, casting and encapsulation. It combines the performance characteristics of epoxy resins such as strength, chemical resistance and adhesive qualities, with those of the polyurethanes including toughness, abrasion resistance and flexibility. In addition EP30DP can be used at cryogenic temperatures. It can be readily cast in thick cross sections, (e.g., several inches) without the development of undue exotherm during cure. Master Bond Polymer System EP30DP is formulated to cure at ambient temperatures or more rapidly at elevated temperatures. This unique polymer system is 100% reactive and does not contain any solvents or diluents. One noteworthy property of EP30DP is that it can be more easily removed than conventional epoxies. The Master Bond EP30DP system cures with minimal shrinkage to a durable, high strength and tough elastomeric solid with remarkably good resistance to thermal cycling, chemicals, water, inorganic salts, alkalis and acid. Serviceable over the exceptionally wide temperature range of 4K to +250°F. Adhesion to metals, concrete, glass, ceramics, wood, vulcanized rubbers, and many plastics is excellent. The cured compound is a superior electrical insulator. Color of part A is clear amber, part B clear yellow. Master Bond Polymer System EP30DP is widely employed in the electronics, electrical, metalworking, appliance, automotive and chemical processing industries. It does not contain any free isocyanate and is quite safe to use when proper industrial hygiene practices are observed.
