Shielding paint NSF34 | LF screening attenuation against electrosmog up to 80 dB | protection against low-frequency electrical fields (domestic electricity) | TÜV SÜD certified

NSF34 is a shielding paint developed for the effective shielding of low-frequency alternating electric fields. LF shielding attenuation up to 80 dB. Without protective effect against electrosmog caused by radio radiation (EMF).

Normally, our focus is on total protection from electrosmog. However, in some cases, a special shielding paint, such as the NSF34 by YSHIELD, can make sense. For example, in an office if the radio reception cannot be impaired if, for example, a structured cabling is missing and all of the computers, laptops, and peripheral devices are connected to WLAN. Or, if there is no landline telephone and communication is only done by mobile phone.

Or, in private rooms such as the living room or home office if your mobile phone has to have reception, but protection from the electric alternating fields goes through the power cabling in the wall. This paint can also be used later under photovoltaic systems if the low-frequency electric field produced by the panels shouldn’t enter the living room.

This special LF shielding is seldom used compared to the all-round electrosmog shielding paint. This NSF34 shielding paint has no use in bedrooms focused on recovery and we advise against its usage.

Shielding Paint NSF34 | Characteristics

The NSF34 shielding paint was developed with a high-quality pure acrylic binder and offers a high attenuation of up to 80 dB against low-frequency electric fields. By using NSF34, it is possible to fully shield yourself from LF loads from electric fields from the power supply. NSF34 is frost-resistant and ideal for year-round shipping. It is also breathable, solvent-free, low-odor and low-emission.

One coat is NSF34 is normally enough. The NSF34 shielding paint must be grounded!

• Screening attenuation: One coat provides 80 dB attenuation against low-frequency electric fields (LF). The shielding attenuation is often measured in the EMC laboratory. The measurement setups used follow these standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07.
• Substrate: Indoors and outdoors. Excellent on adhesion on almost all substrates such as old coats of paint, plasterboards, wallpapers, plaster, concrete, styrofoam, wood, etc.
• Final coating: Preferably covered with plastic-bonded dispersion paints, silicate emulsion paints, façade paints or silicon resin paints. We do not recommend pure mineral paints (clay, chalk, pure silicate). You can find concrete recommendations on the technical data sheet. Due to its high tensile strength (at least 0.08 N/mm² according to ETAG 004 for WDVS), it can be applied directly under pure organic plaster, but not on mineral plaster!
• Grounding: Must be grounded! We recommend the self-adhesive grounding tape for indoor use.
