YSHIELD® DRY54 | EMF Shielding paint-powder | 5 litre


YSHIELD® DRY54 EMF shielding paint-powder with long storage suitability. Without preservatives. Up to 84 dB shielding effectiveness at 40 GHz. 



YSHIELD® DRY54 EMF Shielding paint-powder for shielding high-frequency radiation (HF) and low-frequency electric fields (LF). Special paint with great all-round characteristics – delivered as a powder. Up to now our best powder paint at the best possible price! Breathable, plasticizer-free, low-emission and without a preservation agent. With very good physical and chemical properties, along with very high ecology.

We first produced a powder paint in 2003, but liquid paints become the established ones. The reason for this was the low performance of an electric screwdriver which was not sufficient for the ingredients that needed to be dispersed – in our production we need more than 100,000 Watt for a professional result. After a longer development time we have now found the perfect formula for powdered shielding paints.

Screening attenuation

Variation 1 (more water):
At 1 GHz: Single layer 31 dB | Double layer 38 dB | Three layer 44 dB
At 40 GHz:
 Single layer 30 dB | Double layer 44 dB | Three layer 58 dB

Variation 2 (less water):
At 1 GHz: Single layer 37 dB | Double layer 43 dB | Three layer 48 dB
At 40 GHz:
 Single layer 38 dB | Double layer 57 dB | Three layer 75 dB

For mixing, the required quantities of powder and water are:
Use 1 litre of powder and 0.7 litre of water for 1 litre of paint, in a bucket larger than 2 litres.
Use 5 litres of powder and 3.5 litres of water for 5 litres of paint, in a bucket larger than 10 litres.
The water should be measured accurately to the gram using a digital scale, and the bucket must have at least twice the volume of the paint that needs mixing.

Attenuation dB / %

10 dB = 90 % EMF Shielding
20 dB = 99 % EMF Shielding 
30 dB = 99.9 % EMF Shielding
40 dB = 99.99 % EMF Shielding
50 dB = 99.999 % EMF Shielding
60 dB = 99.9999% EMF Shielding

Technical Specification

  • Grounding: Must be grounded! We recommend interior the grounding tape GSX plus grounding plate GS3 / GF4  And for exterior applications,  fibre additive AF3 plus the grounding plate GF4.
  • Frost resistance: This product is delivered as a powder and thus frost resistant.
  • Ingredients: Untreated natural graphite, carbon black, pure acrylics powder, additives, no preservative agent. Technical data: Please find all technical data and the application details in our technical data sheet.

Delivery Time: Usually between 2 – 4 business days

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 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.

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.

Additional Information

Special characteristics DRY54:

  • This powder shielding paint can be mixed up with more or less water
  • When using alternative 1 (more water), the paint stays nearly as liquid as water while mixing – the dust formation is extremely limited, as the powder blends immediately with the water. The paint becomes thicker after 15 minutes resting time – it can be perfectly painted with afterwards and you will get a nice flow for an even shielding.
  • When using alternative 2 (less water), the paint gets paste-like. Formation of dust and amount of work are higher, the finished amount of paint is approx. 17 % less. The advantage is a 6 dB higher shielding attenuation. The paint becomes as thick as a usual dispersion paint after 15 minutes resting time and can be painted as well as a dispersion paint.
  • The phenomenal price-performance-ratio is achieved, as the DRY54 only costs half as much as our liquid paints. That is why you can paint two times for the same costs.
  • The powder gets bagged and then vacuum-packed three times. Vacuum-packed into one another, using three bags – that is why no moisture will get into the powder, even years later.
  • The powder needs to be mixed with water – what you will need to do so: Digital scales, protective mask, safety glasses, our paint stirrer AR42, a bucket for mixing, a drilling machine (electric screwdriver) and 15-30 minutes of your time.
  • The amount of water must be measured exactly to the gram with a digital scale! The used bucket needs to be at least twice as big as the paint volume to be mixed.
  • Powder package / Needed bucket / Water quantity:
    Powder for 1 litre / > 2 litre bucket / 0.7 litre water
    Powder for 5 litre / > 10 litre bucket / 3.5 litre water


General advantages of powder paints:

  • Has a very long shelf life without water
  • No preservatives necessary
  • Reduced risk of frost damages
  • 50-80 % less plastic waste
  • Less delivery costs (up to 60 %)
  • More security during transit in case of packaging damages
  • Small partial quantities can be taken out of the bag for necessary repair works
