Eccosorb™ CFS 8480

Eccosorb™ CFS 8480

Castable silicone absorber series

ECCOSORB CFS-8480 has a high magnetic loss tangent and is electrically non-conductive. When poured or pained on surfaces, it will suppress surface currents, reduce the reflectivity of objects, and lower the QA of a cavity. It can also be used to mold terminations and attenuators. ECCOSORB CFS-8480 is supplied as a two component kit consisting of a Component A (resin) and Component B (catalyst).
