HSF64 shielding paint, HF attenuation of up to 46 dB, LF grounding mandatory. Ecological compromise by YSHIELD.

The HSF64 shielding paint by YSHIELD is an ecological compromise. Technically convincing, but only suited to indoor use.

With the HSF64 shielding paint, the focus was not only on the chemical composition and the best protection possible, but also on ecology and the environment. Normally, the base or binder of a shielding paint is a pure acrylate, this was changed for the HSF64, whose base is a mixture of potassium water glass and pure acrylate. This base’s asset is better adhesion.

With the HSF64, YSHIELD could increase the shielding attenuation to 46 dB, compared to the HSF54 shielding paint that goes up to 44 dB, that means that the HSF64’s shielding effectiveness is three times higher. An increase of 1 dB doubles the effectiveness. 45 dB is twice as strong as 44 dB and 46 dB doubles the effectiveness of 45 dB. An increase from 44 dB to 46 dB is an enormous increase.

As a dispersion silicate paint, the HSF64 shielding paint has limited moisture resistance and is therefore only usable in indoor rooms. The HSF64 is highly alkaline with a pH of 12 because of the use of potassium water glass. Therefore, the HSF64 shielding paint must be used with protective equipment. HSF64 is breathable, solvent-free, odor netural and low-emission.

Convincing properties of the HSF64 shielding paint

The HSF64 shielding paint by YSHIELD is best suited to the effective attenuation of stress caused by electrosmog from mobile radiation and electric alternating fields. Radio pollution from mobile phones, mobile Internet, WLAN, DECT, GSM, LTE, and many more is attenuated by up to 46 dB, which is an effectiveness of 99.997%. Electric fields from the power supply (alternating current) are grounded very effectively and can be attenuated by 100% (same as PRO54, HSF54 and HSF74).

We always strongly recommend two-coated protection, which means painting twice. The HSF64 shielding paint must be grounded!

• Highly-effective radio attenuation – screening attenuation: One layer of HSF64: up to 39 Db. Two layers: up to 46 dB. 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: Interior: excellent adhesion on almost all substrates such as old coats of paint, plasterboards, wallpapers, plaster, concrete, styrofoam, wood, glass, plastic substrates, etc.
• Final coating: Preferably covered with plastic-bonded dispersion paints or silicate emulsion paints. We only recommend a limited use of mineral paints (clay, chalk, pure silicate). You can find concrete recommendations on the technical data sheet.
• Earth: Must be grounded! We recommend the self-adhesive grounding tape for indoor use and the AF3 additive and GE grounding plate for outdoor use.

Yield of the HSF64 shielding paint

Generally speaking, the yield of a shielding paint is necessary depending on the surface. The more the surface “sucks”, ie. is colored, the more shielding paint is required. We recommend conducting small tests to see how quickly the paint “enters”. We highly recommend using our primer because that will prevent an excessively-high usage of HSF64 shielding paint. The “average” yield is based on a “non-sucking” surface.

• ONE LAYER: 1 liter of HSF64 is enough to cover up to 7.5 m² of an indoor surface
• TWO LAYERS: 1 liter of HSF64 is enough to cover up to 3.75 m² of an indoor surface

You need to mix the HSF64 shielding paint extensively before applying it. The heavier ingredients will have sunk from storage and transport, and this must be corrected. With our stirrer, it is possible to effortlessly and effectively re-mix and re-apply the HSF64 shielding paint. Simply insert it into a standard electric drill and mix for around 5 minutes per container. There should be no more solid remains of the solid ingredients at the bottom of the container – these would make the shielding less effective because they wouldn’t be put on the wall, but they’d remain in the paint bucket.

Mandatory grounding of the HSF64 shielding paint

All electrically conductive surfaces must be grounded by a qualified electrician in accordance to the DIN/VDE regulations. This can be done over the electrical system’s grounding support (ground contact in the socket) or on the grounded heating pipe of the wall heaters (radiator). A protective circuit also needs to be installed in the fuse box. It must be noted that the circuit must be turned off before painting – a 230-volt, 16-amp shock can be deadly! The electrified flush-mounted box must be a centimeter away when painting the wall.

Electrical alternating fields can be grounded, contrary to mobile radiations (high-frequency) which are based on reflection and cannot be grounded as a result. A protection against mobile radiation is also based on reflection whereby the electromagnetic radiation is prevented from entering the room.

The HSF64 shielding paint shields against both emissions by grounding and reflecting electromagnetic radiations.
