DRY65 is an effective powdered shielding paint by YSHIELD to be stirred yourself. The plaster is frost-resistant, lighter and therefore ideal for worldwide shipping.
When developing the DRY65 shielding paint, the focus was on its weight for shipping. For every liquid shielding paint, around 50% of what was sent was water. This is obviously very practical as you can start your shielding work as soon as the package is delivered. However, unnecessary water is also sent, which makes it a lot heavier and increases shipping costs. A water supply is normally available. The shipping weight plays a significant role, even in worldwide shipping. Another benefit of shipping powdered shielding paint is its resistance to frost because there is no water that can be frozen.
The DRY65 shielding paint is a dispersion silicate plaster with a potassium water glass binder and its synthetic content is under 5%. In terms of screening attenuation, DRY65 is comparable to the classic HSF54 and has a high attenuation of up to 43 dB with two coats. As is the case with all electrically conductive shielding products, the DRY65 shielding paint must also be grounded. With this grounding, you will be shielded from the low-frequency electric fields. DRY65 is breathable, solvent-free, neutral odor and low-emission.
DRY65 shielding paint safety warning
DRY65 is highly alkaline (pH: 12) because of the pure use of potassium water glass. Furthermore, because it is made of powder, parts of powder can be swirled into the air when stirring and you can breathe them in. Therefore, the DRY65 shielding paint can ONLY be used with the appropriate safety equipment. We highly recommend the DRY99 safety set designed for this purpose in the Shop.
Convincing properties of the DRY65 shielding paint
The DRY65 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 are attenuated by up to 43 dB, which is an effectiveness of 99.995%. Electric fields from the power supply (alternating current) are grounded very effectively and can be attenuated by 100% (same as PRO54, HSF54, HSF64, HSF74 and T98).
We always strongly recommend two-coated protection, which means painting twice. The DRY65 shielding paint must be grounded!
- Highly-effective radio attenuation – screening attenuation: One layer of DRY65 attenuates by up to 35 dB, 2 layers up to 43 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.
- Delivered as powder to be stirred yourself
- Halved shipping weight because of the lack of water
- Frost-resistance for shipping because it is delivered without water
- Yearly shelf life
- Substrate: Excellent adhesion to almost all absorbent substrates. Not usable on gypsum-based substrates, the potassium water glass cracks the gypsum!
- Final coating: Generally, only organic dispersion paints or silicates adhere to graphite layers. For purely mineral coatings, we recommend a follow-up treatment with GK5 primer concentrate or another primer is that is usable on the coating. Do not use any gypsum-based coatings, potassium water glass cracks the gypsum!
- Earth: Must be grounded! We recommended the self-adhesive grounding tape for indoor use.
Yield of the DRY65 shielding paint
Generally speaking, the yield of a shielding paint is necessary depending on the surface. The more the surface “sucks”, ie. is coloured, the more shielding paint is required. We recommend conducting small tests to see how quickly the paint “enters”. We highly recommend using our GK5 primer concentrate because that will prevent an excessively-high usage of DRY65 shielding paint. The “average” yield is based on a “non-sucking” surface.
- ONE LAYER COATING: up to 7.5 m² per liter
- DOUBLE-LAYER COATING: up to 3.75 m² per liter
DRY65 shielding paint is preferably used indoors. DRY65 is suited to outdoor use as well thanks to its moisture resistance. Preparing the shielding paint takes approx. 40 minutes. A container contains 2.7 kg of shielding powder and is mixed in a bucket with 3.3 liters of water. Stirring the plaster can only be done with suitable painting equipment. Stirring by hand is impossible and leads to a lumpy shielding paint that does not provide good protection and may not be applicable.GK5 primer
Mandatory grounding of the DRY65 shielding plaster
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 DRY65 shielding paint shields against both emissions by grounding and reflecting electromagnetic radiations.Grounding tape for shielding paints
