With a Shore D hardness exceeding 95, EP21SC-1 is a rigid compound that adheres well to treated metals, ceramics and many plastics. Its physical strength profile includes a tensile strength greater than 6,000 psi and a compressive strength of over 15,000 psi at room temperature. Since the system is 100% reactive and does not contain any solvents or diluents, it has minimal shrinkage upon cure. Additionally, EP21SC-1 is capable of withstanding a range of chemicals such as water, oils, hydraulic fluids, acids and bases. The combination of the aforementioned properties enables this system to be widely employed for maintenance and repair of pumps, chutes, centrifuges, impellers and tanks.
EP21SC-1 is serviceable from -60°F to +250°F. It is a competent electrical insulator and it has a low thermal expansion coefficient. Both Parts A and B are dark gray in color and are available in standard packaging ranging from pint to 5 gallon container kits.
Master Bond EP21SC-1 features abrasion resistance and convenient handling for bonding, coating and sealing applications. This two component epoxy also resists a variety of chemicals.
