EP30-3

Master Bond EP30-3 is a two component epoxy system featuring a combination of optical clarity and light transmission, an impressive glass transition temperature (T_g), along with amazing chemical resistance. It has an easy to use 100 to 30 mix ratio by weight, and while it requires heat curing 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. EP30-3 has substantial 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. Also compelling is its high T_g greater than 175°C, which is super 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.
