Master Bond Polymer System EP30D-15 is a uniquely versatile two component optically clear urethane elastomer featuring superior strength, flexibility and chemical resistance for high performance bonding, sealing, casting, potting 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 polyurethane's characteristic toughness, abrasion resistance and flexibility. Master Bond Polymer System EP30D-15 is formulated to cure at room temperature or more rapidly at elevated temperatures, with a user friendly one to one noncritical mix ratio on a weight basis. It is 100% reactive and does not contain any solvents or diluents. This specially clear, low viscosity polymer system cures with minimal shrinkage to a remarkably high strength and flexible thermoset plastic with very superior resistance to thermal cycling and chemicals including water, inorganic salts, alkalis and acids. Master Bond Polymer System EP30D-15 can be used over the exceptionally wide temperature range of -60°F to +250°F. Adhesion to metals, glass, concrete, ceramics, wood, vulcanized rubbers and many plastics is excellent. The cured material is an electrical insulator. Color of part A is clear, part B clear. Master Bond Polymer System EP30D-15 is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical process industries. It is quite safe to use when proper industrial hygiene practices are observed viscosities and cure times can be readily adjusted within wide limits so as to best meet specific application requirements.
