Description
Area of Application
For small areas by using a double sided adhesive tape or for large-surface applications with glue. Can easily be bent and folded and be cut with scissors or a knife.
Corrosion resistanceGood corrosion resistance in a normal environment.AttenuationAttenuation for low frequency sources of electric and magnetic fields, depending on application in one layer, is 14dB (shielding effectiveness of 80%). For high frequency sources of electric and magnetic fields the attenuation in one layer is 100dB The shielding attenuation is regularly tested by Professor Dipl.Ing. Pauli at the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The expert reports are available upon request.

Material Application
Processing
In the case of processing in electronic applications, standard double sided adhesive tapes can be used for bonding on the surface. For walls, ceilings and floors (for shielding cables or fuse boxes) use viscous glue with high adhesive strength. The strips of the foil should be overlapped at least 1 cm. Fuse boxes should be shielded with at least 2 x 2m! After drying, NMF25 can be painted over with commercial diespersion paint.
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 strap EB in combination with our grouding set ES.
