EP38 Product Information

Master Bond EP38 is a faster curing, lower viscosity, optically clear two component epoxy system for highperformance bonding, coating, sealing and small encapsulations. The mix ratio is 100:33 by weight. EP38 sets up and cures very quickly; even thinner coatings (0.004-0.005 inches thick) will be tack free in about 3 hours at room temperatures. Additionally, its shrinkage upon curing is exceptionally low. Once cured, EP38 offers superior
optical clarity and a smooth, glossy appearance. It is also very impressive in resisting a wide array of chemicals which will be mentioned in more detail below. One noteworthy feature regarding chemical resistance is its ability to withstand boiling water.

Additionally, EP38 has first rate electrical insulation characteristics. It bonds well to a wide variety of substrates, such as metals, ceramics, glass, composites, many rubbers and plastics. Its physical properties are also favorable, especially its high tensile and compressive strength. The service temperature range is -60°F to +250°F. This highly attractive combination of properties enables EP38 to be used in a variety of aerospace, electronics and optical applications, as well as in tanks, pipes, fittings and other similar OEM and repair applications.
