EMF Shielding mesh HNS80 | Self-adhesive | Metres

Description

EMF Shielding mesh HNS80 is a compact woven metallized polyester mesh for the large-scale shielding of high-frequency radiation (HF) and low-frequency electric fields (LF). Self-adhesive with electrically conductive glue. Commercial product for data centres, laboratories, TEMPEST rooms, now available for private use.

Application

For application on walls, ceilings and floors, the substrate needs to be perfectly even. Wall paints, dry constructions boards, etc. need to be filled and sanded evenly. Afterwards you need to apply a layer of primer. The main use is shielding doors, window frames, boxes, cases, devices, machines and many other technical applications.

Processing

It is best to process the mesh with two people. One person holds the sheet on the right and left side in position, with some distance to the substrate. The other person removes the protective film and presses the mesh with a scraper (e.g. our plastic scraper FVR10) strongly onto the substrate. As soon as the mesh is glued properly, press it once more strongly onto the substrate so that the glue can deploy its best adhesion. We recommend practising this at first for larger surfaces. Due to the electrical conductivity of the glue you can fix the sheets with an overlapping – if the edging is bothering you, you can level it out. When using wall paint on top of the mesh, please take into consideration that the material contains copper, the pH value of the paint must not be higher than 8 – therefore mineral paints are not permitted to be used on top of it.

Attenuation / Grounding

• This product shields high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Laboratory report ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006, view report above.
• This product with an electrically conductive surface shields low-frequency alternating electric fields (LF). For this purpose a grounding is necessary, i.e. an integration into the functional-equipotential bonding (FEB), please find suitable grounding accessories under “EMF Shielding Grounding Accessories“.
