Processing
In case of processing HNG80 as an intermediate layer we recommend using our dispersion glue DKL90 for adhesion. The wall and the backside of HNG80 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 DK90 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. If that is not possible, we recommend using our shielding paint HSF54.

Grounding
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 plate Magnet - GM, in combination with Grounding cable GC-200 Plugged into Grounding plate Tube-GT/Attach to Heating Pipes for loose laying application, or our perforated stainless steel tape ELB for application in drywall constructions. For adhesion to walls use our Grounding plate Wall - GW with grounding strap EB-1 in combination with our dispersion glue DK90. Also available: 3 pin UK earth plug

Shielding attenuation
The shielding attenuation is regularly tested in our own EMC laboratory. We have measurement setups due to the following standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07. You'll find the PDF test report above on this page.
