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. 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.
