Master Bond EP30-3LO is a two component epoxy system featuring a combination of optical clarity and light transmission, an impressive glass transition temperature (Tg), amazing 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 tip-top electrical insulation properties and first rate 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 compelling is its high Tg greater than 175°C, which is phenomenal 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
