Master Bond EP112LS is a two-part epoxy that is well-suited for impregnation, potting, encapsulation, sealing, and coating applications, particularly in the aerospace and optoelectronics industries.

EP112LS is optically clear, features reliable non-yellowing properties, and has a refractive index of 1.55. This electrically insulative system is resistant to chemicals, including water, oils, fuels, acids, and bases. EP112LS is serviceable over the temperature range of -60°F to +450°F.

This system features a working life exceeding 2-3 days at room temperature and requires oven-curing. Post-curing will enhance its properties. With a mixed viscosity of 50-200 cps, EP112LS bonds well to a wide variety of substrates, including metals, composites, glass, ceramics, and many rubbers and plastics. Bonds feature a tensile strength, compressive strength, and tensile modulus of 11,000 psi, 20,000 psi, and 400,000 psi at room temperature, respectively. Dimensional stability is outstanding.

EP112LS has a shelf life of one year in original, unopened containers, and is available in ½ pint, pint, quart, gallon, and 5 gallon container kits.
