SHIELDING PLASTER DRY69

• Shielding PLASTER for high frequency electromagnetic fields, and also  low frequency electric field E, powder for 5L . [60dB @ 1 mm. thickness]​​ 

  

CHARACTERISTICS

 

Shielding plaster delivered as a powder. Dispersion silicate plaster with potassium silicate as binder and under 5 % synthetic content. For the shielding of high-frequency radiation (HF) and low-frequency electric fields (LF).

• Delivered as a powder to mix yourself.

• Low shipping weight.

• Frost resistant on shipping.

• Shelf life for years.

• Breathable, solvent free, low-emission, low odor.

• Attenuation: 60 dB at 1 mm thickness, 70 dB at 1 mm thickness. The shielding attenuation is regularly tested in our own EMC laboratory. We have measurement setups due to the following standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07.

• Coverage: 20 m2 at 1 mm. thickness. 10 m2 at 2 mm. thickness

• Packaging size: 12 kg powder for 20 liters of paint.

• Application: Wall exterior, Wall interior, Ceiling, Floor.

 

SPECIAL FEATURES

• This shielding plaster contains no long carbon fibers for shielding, which is why it shields equally well in all polarisation directions.

• This plaster has a relatively high diminution of 50 % while drying. This is very important for the high attenuation. It should only be used on smooth undergrounds as unevenness can’t be smoothed with this plaster.

• Carbon pigments are black, in which shielding plaster would you trust? Instead of cheap filler materials, we use costly carbons exclusively, see the right sample in the picture. Thereby we don´t reach only 24 dB attenuation, but sensational 60 dB.

 

SAFETY INSTRUCTIONS

This product with a pH-value of 12 contains potassium silicate powder. Stirring is ONLY ALLOWED with protective equipment! We urgent recommend our safety-set DRY99, see accessories.

 

USAGE

As a thin layer plaster with a thickness from 1 mm to 2 mm preferrably interior. But due to the good moisture resistance even exterior.

 

PREPARATION

Stir the 12 kg powder in a bucket with 12 liters of water. Preparation time appr. 70 minutes.

 

UNDERGROUND

We recommend a surface preparation with our primer concentrate GK5 or another primer. Excellent adhesion on almost all absorbent undergrounds. Not applicable on gypsum based undergrounds, potassium silcate peels off from gypsum!

 

FINAL COATING

Sand and smooth elevations and coarse burrs as usual. Normally on the graphite surface only organic dispersion paints or dispersion silicate paints adheres well. For pure mineralic coatings we recommend an aftertreatment with our primer concentrate GK5 or another for the coating suitable primer. 

 

INGREDIENTS

Graphite, potassium silicate powder, carbon black, acrylics powder, additives.

 

GROUNDING

Electrically conductive. Can be contacted and grounded to shield electric fields (LF). Please find corresponding components under "Grounding".
