ENVIRONMENTAL PROPERTIES
• Eccosorb AN is not waterproof and will not operate correctly when wet. Since there is no
washout, it will function as expected after being allowed to dry.
• A special CERSEAL coating to prevent moisture uptake in high humidity to moderately wet
environments is available on special request.
• For high humidity to moderately wet environments, sealed versions of Eccosorb AN are
available. They are essentially the same material as Eccosorb AN but the absorber is sealed to
provide improved outdoor properties.
The available types are :
Eccosorb AN-xx-W :sealed with neoprene coated nylon fabric, color olive green.
Eccosorb AN-xx-WPC : sealed with a poly-urethane coating, different colors available on request
Eccosorb AN-xx-WPVC :sealed with a PVC plastic, different colors are available on request and
can be provided with eye-lets for fixing
• Reflectivity performance is similar to the standard Eccosorb AN product;
INSTRUCTIONS FOR USE
• To obtain low reflectivity, the absorbers must be mounted on a metal surface. If a metal surface
is not available, Eccosorb AN can be supplied metal backed with aluminum foil (ML).
• For correct operation, Eccosorb AN must have the white (front) face towards the signal to be
attenuated.
• Layering of multiple pieces or slicing off part of the thickness will degrade the overall
performance.
• Reflectivity performance also degrades for off-normal bistatic incidence and at different rates
for different polarizations.
• Eccosorb AN can be securely bonded to itself or to other materials such as metal, wood, and
common plastic composites. Our specific Eccostock® foam adhesive is recommended.
