HSF54 – EMF and RF Shielding Paint 5L


(Internal/External use)

New & Improved

Shielding paint for shielding high-frequency electromagnetic fields (HF) and low-frequency alternating electrical fields (NF). Our best-selling product, proven ten thousand times over. One color for everything if you can’t decide. Improved again in 2019. Breathable, solvent-free, plasticizer-free and low in emissions. With outstanding physical and chemical properties combined with high ecology.

Shielding Effectiveness

Single layer 39 dB | Two-layer 49 dB | Three layers of 59 dB


Excellent adhesion to all common surfaces indoors and outdoors.


Can be reworked preferably with plastic-based emulsion paints, emulsion silicate paints, facade paints or silicone resin paints.


Must be grounded! We recommend the EB2 grounding strip plus GW grounding plate indoors and the AF3 fiber additive plus GE grounding plate outdoors.

Optional: AF3 fiber additive

For bridging cracks for better earthing, we recommend our fiber additive AF3 with long conductive carbon fibers.

Frost resistance

This product is frost-resistant (5 tested frost / thaw cycles) and can be shipped all year round by air / sea.


Water, natural graphite, pure acrylic dispersion, carbon black, additives, preservatives (BIT, INN, MIT).

Technical specifications

You will find these in detail in the overview table and in the technical data sheet.

As a coating in technical applications

With the fine pigmentation of 50 µm, high film hardness, good substrate wetting, high adhesive tensile values ​​and Newtonian rheology … our customers have discovered more and more technical applications over the years: Technical shielding of parts, devices, machines or systems. Manufacture of absorber materials or pressure sensors. Screen printing on heating foils or plasterboard.

Shielding Report

TÜV-SÜD certificate



Ready for  5G……………

Safety up to 40 GHz

TÜV Certification

No Nanotechnology

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)
We have a professional EMC-laboratory according to various standards up to 40 GHz on site, which is operated by long-time experienced staff. You’ll receive independent measuring curves and reports from 40/600 MHz – 40 GHz with all our shielding products. We have our shielding paints monitored by TÜV-Süd. The whole production process including quality control, emission behavior and economical use of preserving agents is subject to monitoring. Please find the certificate above at the downloads. 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.
