Material Notes:
Description: Master Bond EP30HV is a lower viscosity, two component epoxy system for high performance bonding, sealing, coating and potting. It is formulated to cure at room temperature or more rapidly at elevated temperatures. It has an easy to use, non-critical four to one mix ratio by weight. This system is 100% reactive and does not contain any solvents or diluents. It is especially recommended when low viscosity, excellent physical strength properties along with optical clarity are required. It has low linear shrinkage upon curing, less than 0.1%. EP30HV forms high strength, rigid bonds with superior dimensional stability. It resists many chemicals including water, oils, fuels, acids, bases and solvents. It adheres well to a wide variety of materials including metals, composites, glass, ceramics, rubbers and many plastics. The cured epoxy has top notch electrical insulation properties. EP30HV possesses outstanding optical clarity and light transmittance from 350 to about 2,400 nm. The service temperature range is -60°F to 300°F. This versatile system can be used in the aerospace, electronic, optical, opto-electronic and specialty OEM applications. Product Advantages: Convenient mixing: lower viscosity, easy to apply. High physical strength properties. Forms dimensionally stable, rigid bonds. Good optical clarity, high light transmission properties. Outstanding electrical insulation properties; well suited for smaller pottings. Good chemical and temperature resistance. Meets FDA requirements for indirect food related applications.Information provided by MasterBond®
