As shielding paint for rooms and buildings

Shielding paint for shielding high-frequency radiation (HF) and low-frequency electric fields (LF). Breathable, solvent-free, plasticizer-free, low-emission and without preservation agent.

Special paint with a focus on high ecology, minimalistic formula without preservative agents. Up to 93 dB at 40 GHz. TÜV SÜD certified. Shields nearly as well as our standard paint HSF54. But: adhesive tensile strength, abrasion resistance and film hardness are not as good as with our other paints. This dispersion-silicate paint needs a silicifiable substrate. The paint is coarsely pigmented, easy to process and forms an even film.

Screening attenuation

At a yield of 4 sqm/l:
At 1 GHz: Single layer 43 dB | Double layer 50 dB | Three layer 54 dB
At a yield of 8 sqm/l:
At 1 GHz: Single layer 36 dB | Double layer 43 dB | Three layer 48 dB


Adhesion on almost all absorbent substrates interior.

Top coating

Preferably covered with plastic bonded water-based emulsion paints, dispersion silicate paints or silicon resin paints.


Must be grounded! We recommend interior the grounding strap GSX plus grounding plate GS / GF.

Frost resistance

This product is frost resistant (proved for 5 frost-/thaw cycles) and can be shipped throughout the year by air cargo or ship.


Water, potassium silicate, natural graphite, carbon black, pure acrylics dispersion, additives, NO preservation agent.

Technical data

Please find detailled data in the table overview and the technical data sheet.

Ready for 5G

As we keep on developing our paints, they now have an almost linear shielding attenuation for a very large frequency range. This frequency range has already been including both 5G frequency spectrums for quite some time: FR1 (600 MHz - 6 GHz) and FR2 (24 GHz - 40 GHz).

Safety up to 40 GHz

We already invested in our own professional EMV laboratory many years ago, as external laboratories and experts could no longer fulfil our increasing expectation to a 140 dB measuring dynamics and 40 GHz. We not only issue our own shielding reports therein but also check each and every batch for your security on a daily basis. You receive measuring curves and laboratory reports up to 40 GHz with each of our shielding products, by which we bindingly guarantee the shielding effectiveness.

No nanotechnology

Our shielding paints are developed in accordance with strict ecological criteria. We use, for example, the carbon black with the lowest emission possible on the market and untreated natural graphite. We consciously do not use graphene, a nanomaterial where the hazard potential is still completely unknown.

TÜV-SÜD certification

We have our shielding paints monitored by TÜV-SÜD. The whole production process including quality control, emission behaviour and economical use of preserving agents is subject to monitoring. Please find the certificate above at the downloads.
