Technical Data Sheet - K1082

K1082 is a high performance, carbon-based, filler material that has excellent thermal, conductive, and physical properties. It is used as the filler between magnets in assemblies, magnet systems, and magnet arrays. It is especially popular with rare-earth (Neodymium Iron Boron and Samarium Cobalt) magnet assemblies.

K1082 is superior to the conventional potting compounds since it can withstand very high shock impact and temperatures without changing its physical properties. The carbon base gives it extreme longevity. Since plasticizers are not used, the material properties do not change with time, temperature, or exposure to other harsh environments.
