This professional product with more than 100 dB attenuation is typically used for ministries of defence, banking houses, laboratories, etc. Where competitors advertise with 100 dB, they ignore the fact that the attenuation usually drops to some 80 dB at higher frequencies which is identically to our HNG80 or HNV80! We had produced HNG100 with a very high metal content. With a restistance/square of only 0.003 Ohm and a close mesh-width the HNG100 achieves real 100 dB even at high frequencies.

Surface conductivity: 0.003 ohm (square resistance)
In case of processing HNG100 as an intermediate layer we recommend using our conductive dispersion glue DKL90 for adhesion. The wall and the backside of HNG100 should be coated with a paint roller. Insert the material wet on wet. Fix it manually (with disposable gloves) and press a gummed roller against the fleece to get a crease-free surface. Work quickly and strip by strip only so that the DKL90 glue does not dry. A crease-free adhesion is only possible on perfectly level surfaces! Structured surfaces (ingrain wallpaper, textured plastering) have to be smoothed.
Due to the highly conductive surface this material can be contacted and grounded easy to shield low frequency (LF) electric fields. For professional grounding we recommend our grounding plug EST for self laying application, or our grounding strap EB in combination with our grouding set ES for adhesive bonding with our dispersion glue DKL90.
The shielding attenuation is regularly tested by Professor Dipl.Ing. Pauli at the Microwave Laboratory of the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The line in the diagram stands for the radial direction of polarisation (both directions, horizontal/vertical) and indicates the attenuation achievable in practice. You find the expert report above.
