Master Bond Polymer System EP30D-7 is a versatile two component flexibilized, urethane-modified epoxy featuring superior strength, toughness and abrasion resistance for high performance bonding, sealing, coating, potting and encapsulation applications. It combines the advantageous performance characteristics of epoxy resins such as strength, chemical resistance and adhesive qualities, with those of polyurethanes including toughness, abrasion resistance and flexibility. Master Bond Polymer System EP30D-7 is formulated to cure at room temperature or more rapidly at elevated temperatures, with a 100 to 20 mix ratio by weight. It is 100% reactive and does not contain any solvents or diluents. The EP30D-7 system cures with minimal shrinkage to a durable, high strength, toughened system with good resistance to thermal cycling and chemicals such as water, fuels and various inorganic solvents. It is serviceable over the wide temperature range of -100°F to +250°F . Its adhesion to metals, glass, ceramics, a variety of plastics, and many rubbers is excellent. The cured elastomer is an electrical insulator. The color of part A is black and part B amber-clear. Master Bond Polymer System EP30D-7 is widely used in the electronic, electrical, computer, metalworking, appliance and chemical process industries.
