A typical cure schedule is 2-3 hours at 250°F followed by 5-8 hours at 300°F with a 2 hour or longer post cure at 350°F, although, a number of variations are possible. It has excellent adhesion to a wide variety of substrates including metals, composites, glass, ceramics and many rubbers and plastics.
EP121CL-LO is particularly prominent for applications involving rigorous electrical insulation properties. Another attractive feature is its excellent physical strength profile. It offers superior chemical resistance to water, oils, acids, bases, fuels and many solvents. The service temperature range is -80°F to +500°F. EP121CL-LO is a specialty type system that is used in a variety of aerospace, electronic and OEM type applications.
