YSHIELD HSF74/HF+LF Shielding Paint

Protection from High Frequency Telecoms Radiation & Electric Fields

Electro-conductive primer coating for the shielding against high-frequency radiation (HF) and low-frequency electric fields (LF). As a pure silicate paint HSF74 contains potassium silicate as binder.
Developed with an absolute minimum of ingredients for a maximum ecology.

Preservative-free, highly breathable, free of solvents, free of VOC, etc. Good mechanical and chemical properties, nevertheless our standard paint HSF54 is better in all details. HSF74 should only be chosen, when a maximum of ecology is required. Our ecological alternative, metal-free, low-emissions, free of preservatives, only for interior use.

Technical Specification

Screening attenuation: One layer 39 dB, two layers 45 dB. 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.
Common: Our shielding paints, shielding with carbons have many advantages, see common characteristics below.
Application (coverage): Interior (7.5 m²/l).
Underground: (Interior) Good adhesion on absorbent, untreated, preferably mineral undergrounds like chalk, silicate, clay, etc.. Restricted use on absorbent emulsion paints, wallpapers, etc., please check first! Not usable on gypsum based substrates!
Top coating: Preferably covered with plastic bonded, water-based emulsion paints or dispersion silicate paints. We restricted recommend pure mineral paints (clay, loam, chalk, silicate). Please find appropriate product recommendations in the technical data sheet.
Ingredients: Potassium silicate, graphite, water, carbon black, emulsifier, defoamer, cellulose, no preservative agent.
VOC-content: 0.1 g/l (the EU limit value for category A/a is 30 g/l from 2010).
Sd-value: 0.02 m.
Ph-value: 12.
Adhesive tensile strength: 1.7 N/mm².
Shelf life: 12 months.
Colour: Black
Grounding: Must be grounded! We recommend interior the Grounding Strap EB2 plus Grounding Plate GW, with Grounding Cable GC-200 Plugged into Grounding Plate Tube-GT/Attach to copper heating pipes or Grounding Plug GP - (German & French) also available: 3 Pin (UK) Earth Plug , exterior the Fibre Additive AF3 plus the Grounding Plate GE with Grounding Rod GR-100/Exterior

Delivery Time: Usually between 2 - 3 working days

Common characteristics:
Easy handling and processing
YSHIELD shielding paints can exceedingly be applied for all purpose. Compared to wallpapers, fleeces or nettings they are easy to apply, All paints are best applied with a paint roller.

Perfect corrosion resistance
Our shielding paints do not contain any metals but a mixture of carbons instead. That's why our shielding paints are chemically stable and permanent corrosion-free, even in damp environment.

Emissions VOC / PAH
Our shielding paints are tested regularly from the TÜV-SÜD on the content of VOC (volatile organic compounds) and PAH (polycyclic aromatic hydrocarbons). 1) The actual VOC limit is 30 g/l, our paints contain only 0.1 g/l to 1 g/l. 2) The recommended PAH limit (for category 1) is 0.2 mg/kg. Our paints contain 0.002 mg/kg, so they are 100 times below the limit for children toys.

Any kind of aqueous paint must be preserved. Controversial, is the use of Isothiazolinone- compounds, referring to CIT only. CIT is not contained in our paints. Further to this we reject preservation with BIT/silver, like utilized in eco-paints, as we don't want to use nanosilver. Our preservation with MIT/BIT has a very low allergenic potential, which is regularly confirmed by MCS-customers. As an alternative, our shielding paint HSF74, is free from any kind of preservatives.

Due to its paint-typical holohedral structure without holes, our shielding paints provide a nearly linear attenuation up to very high frequencies, regardless of the direction of signal polarization. Proved up to 18GHz they are very future-proof.
