Master Bond Polymer System EP30DPF is a new versatile two component epoxy/urethane elastomer compound featuring superior strength, toughness, abrasion and chemical resistance for high performance bonding, sealing, casting and encapsulation applications. It combines the recognized advantageous performance characteristics of epoxy resins such as strength, chemical resistance and adhesive qualities, with those of the polyurethanes including toughness, abrasion resistance and flexibility. It can be readily cast or spread at either ambient or elevated temperatures even in thick cross section thickness (e.g. several inches) without the devel-opment of undue exotherm during cure. Master Bond Polymer System EP30DPF is formulated to cure at ambient temperatures or more rapidly at elevated temperatures, with a 100 to 20 mix ratio on a weight basis. This unique polymer system is 100% reactive and does not contain any solvents or diluents.

The Master Bond EP30DPF system cures with minimal shrinkage to a durable, high strength and tough elastomeric solid with remarkably good re-sistance to thermal cycling and chemicals including water, inorganic salts, alkalis and acids as well as many organic chemicals over the exceptionally wide temperature range of -60°F to more than 250°F. Adhesion to metals, concrete, glass, ceramics, woodsvulcanized rubbers and many plastics is excellent. The cured compound is a very superior electrical insulator. Color of part A is opague gray, part B clear yellow. Master Bond Polymer System EP30DPF is widely employed in the electronics, electrical, computer, 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.
