HSF64 is our shielding paint which does not contain any preservatives. Suitable for indoor use only! 2019 revised again and further optimized for 5G. Now up to 54 dB shielding effectiveness at 40 GHz. TÜV SÜD certified!
The HSF64 shielding paint from YSHIELD focuses on people with an allergy to preservatives. This shielding paint was developed according to a minimalist formula based on potassium water glass. This results in slight limitations in film hardness, adhesion and shielding compared to alternative HF shielding inks HSF54 or PRO54.
HSF64 was revised, modernized and optimized in 2019 after several years for even more efficient shielding effectiveness compared to the previous formulation of HSF64. Today, the focus is logically on 5G, even if this was not decisive for this further development of HSF64, the previous formulation was already perfectly suited for this purpose. This new formulation of HSF64 makes it possible to combine the previous shielding paints HSF64 and HSF74 without having to sacrifice a valuable property.
Due to the minimalistic formulation the shielding performance per coat is lower. This represents a weakening in direct comparison with alternative shielding paints. For this reason the triple coating of HSF64 shielding paint is explicitly recommended, the double coating is considered the minimum and a must.
HSF64 is now also a frost-resistant shielding paint and can therefore be shipped all year round for the first time. HSF64 is therefore also suitable for parcel shipment in winter as well as on pallets for trucks, trains and ships. Furthermore, HSF65 is highly breathable, solvent-free, plasticizer-free, low-emission and preservative-free. I.e. outstanding physical and chemical properties combined with very high ecology. This performance is confirmed by the TÜV SÜD certification.
Convincing properties of the HSF64 shielding paint
The shielding paint HSF64 from YSHIELD is ideally suited for the very effective shielding of exposure to electrosmog from radio radiation and alternating electric fields. Radio pollution from mobile phones, mobile Internet, WIFI, DECT, GSM, LTE, 5G, etc. is shielded up to 54 dB, which corresponds to an effectiveness of 99.999%. Electrical fields from domestic electricity (alternating current) are grounded extremely effectively and can be completely shielded up to 100%.
We generally recommend painting in two, but it is better to paint in three layers. The HSF64 shielding paint must be grounded!
- Effective RF shielding. Screening attenuation: Single layer HSF64 shields up to 32 dB, two layers up to 40 dB and three layers up to 48 dB at 1GHz. At higher frequencies up to 40 GHz incl. 5G, the shielding is significantly higher again, up to 54 dB. The shielding effectiveness is regularly measured in the EMC laboratory. Test setups according to the following standards are used: ASTM D4935-10, IEEE Std 299-2006, IEEEEEE Std 1128-1998, ASTM A698/A698M-07.
- Substrate: Good adhesion on absorbent, untreated, preferably mineral substrates such as chalk, silicate, clay, cement, etc.. Not usable on gypsum-based substrates (plasterboard, …)! After checking on a test surface, you can use small amounts of paint on absorbent dispersion paints, wallpapers, etc.
- Final coating: Preferably covered with plastic-bonded dispersion paints or silicate emulsion paints. We recommend restricted use of pure mineral paints (clay, chalk, pure silicate). You can find concrete recommendations on the technical data sheet.
- Grounding: Must be grounded! We recommend the self-adhesive grounding tape for indoor 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. absorbing paint, 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.
- Up to 7.5 m² per liter is enough for INDOOR USE of HSF64
(single layer up to 7.5 m², two layers up to 3.75 m², three layers up to 2 m²)
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 the stirrer that we have developed ourselves 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.Stirrer for shielding paints GK5 primer
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 shielding paint HSF64 protects against both electrosmog immissions. I.e. from alternating electric fields by means of earthing and high-frequency electromagnetic fields by means of reflection.Self-adhesive conductive grounding tape for shielding paint Conductive carbon fibers as an invisible alternative to the ground tape
