Its special composition with carbon fibres makes all the difference!
The significant advantage of our shielding paint CFA40 in comparison to other shielding paints is that it contains an innumerable amount of electrically conductive 3 mm carbon fibres, which ensure the surface connectivity essential for a safe grounding by reliably bridging any gaps or cracks in the surface. No further need for grounding tapes. Only ONE punctual connection to ground potential („building ground") is needed for any connected surface. For this purpose we recommend our cost-efficient grounding kit EPK eco, which contains all necessary components for a standard ground connection, which should, however, be done by a qualified electrician.
Sustainable protection - shielding attenuation also for frequencies way beyond 10 GHz
Shielding performance of up to 99.98 % (38 dB) for single layer coatings, and up to 99.996 % (44 dB) for double layer coatings. Tests performed up to 18 GHz prove its effectivity also for new and increasingly higher frequency ranges.
Typical for any paint, the decisive advantage of the CFA40 shielding paint in comparison to wallpapers, fleeces or nettings is its easy handling. Any expert painter can apply this paint using a common paint roller without the need for further instructions or special know-how.
Top coating with common wall paints
CFA40 is a pure acrylic synthetic emulsion paint, allowing a perfect adhesion of most common plastic-bonded emulsion paints. We can also recommend all KEIM sol-silicate and emulsion silicate paints. Natural resin dispersion paints also have a relatively good adhesion, depending on their composition. Paints with pure mineral coatings, such as clay or chalc (except AURO 344), cannot be recommended.
Long lasting and corrosion-resistant
Many metal-based shielding products are not resistant to corrosion. The shielding paint CFA40 does not contain metal particles, but rather a mixture of carbonates, which makes it chemically stable, long lasting and permanently non-oxidising, even in humid surroundings.
Carefully selected ingredients
CFA40 shielding paint is free of solvents, plasticisers, or any other harmful ingredients. All ingredients are selected exclusively on the basis of their quality and harmlessness, independent of their price.
The VOC emissions (volatile organic compounds) of the CFA40 shielding paint have been tested in an independent and accredited laboratory according to the standards of ChemVOCFarbV. Since 2010, the legal maximum value for the product category A/a is 30 g/l. The CFA40 shielding paint has a value of 0.2 g/l, which means it is 150 times lower than currently decreed.
Shielding attenuation tests
The shielding attenuation is regularly tested in the manufacturer's laboratory or by Prof. Pauli of the German Army University in Munich, always referring to the standards ASTM D4935-10 and/or IEEE-STD-299-2006.
Fields of application
The shielding paint CFA40 offers a great variety of application possibilities: In private surroundings for a protection against mobile phone base stations, radio stations and networks, radar services, cordless phones, or power lines. In the economic, scientific, and research sector for skimming and bugging protection or material and facility shielding. In the medical sector to prevent falsified patient measurement values (such as ECG/EEG). In the industrial sector, for instance in the development dept. of car manufacturers. In prisons to prevent unauthorised mobile phone communications. Further possible areas of application: computing centers, engineering rooms, schools, kindergardens, hotel rooms, sick rooms, recording studios, ...
