Master Bond EP30-3LO Highly versatile, two part epoxy system for bonding, coating, sealing and casting

Master Bond EP30-3LO is a two component epoxy system featuring a combination of optical clarity and light transmission, good glass transition temperature (Tg), great chemical resistance along with passing NASA low outgassing testing requirements. It has an easy to use 100 to 30 mix ratio by weight, and while it requires heat curing (see below for details) it offers a long open time of 6-10 hours. It bonds well to a wide variety of substrates including metals, glass, composites and many plastics and rubbers. EP30-3LO has good electrical insulation properties and chemical resistance, particularly to water, oils, acids, bases and many solvents. This versatile system can be used for bonding, sealing, coating and potting applications. An added dimension is its compliance with NASA low outgassing requirements. Also ling is its high Tg greater than 175°C, which good for an epoxy with these kinds of optical properties. The service temperature range is -80°F to +450°F. It can be used in aerospace, electronics and most frequently in opto-electronics and optical applications Product Advantages: Convenient mix ratio; 100:30 by weight Low viscosity, easy to apply; very long working life High bonding strength to metals, many plastics, rubber and glass Excellent chemical resistance to acids, bases, oils and solvents Good optical clarity and transmission Outstanding electrical insulation; can be used for potting and encapsulation Resistance to many chemicals including solvents, fuels, acids and bases Bonds well to a wide variety of substratesInformation provided by MasterBond
