Areas of application
In private areas for the protection against cell phone towers, TV and radio broadcasting antennas, radar, digital standard cordless teleÂphones, wireless networks or power supply lines. In commerce, science, research and defence facilities to prevent interception of data from wireless networks (data-stealing), to protect potentially bugged conference rooms or to shield technical equipment. At military facilities or airports to protect against radar. In the mediÂcine to prevent wrong measurements in patients (ECG/EEG). In the industry, e.g. at car- or computer producers in development deparments. In prisons to hamper unauthorized cellular calls. Further applications: Data centers, technical rooms, schools, nurseries, hotel rooms, hospital rooms, recording studios, etc.
Corrosion resistance
Without metal particles and therefore long-term durable and not oxidizing.
Attenuation
Attenuation depending on application in one layer 30-40 dB (shielding effectiveness of 99.9 - 99.99 %) or in two layers 35-45 dB (shielding effectiveness of 99.97 - 99.997 %).

Pauli at the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The expert reports are available upon request.

Grounding regulation
Only skilled electricians listed in the register of your electricity supplier are permitted to execute grounding measures! Pay attention to the following points: Protective measures against electric shock to DIN 57100/VDE 0100 part 410 + part 540, grounding to DIN/VDE 0100 part 410 + part 540, visual inspection and process testing to DIN/VDE 0100 part 610 part 4+5 and EMC to VDE 0100. Grounding measures are only permitted in TNS or TT networks! Grounding measures may never be executed in network forms with combined PEN wiring! A leakage/fault circuit breaker (FI/RCD) with less than 30 mA must be installed. Find more information on this in our grounding instructions sheet.
Grounding accessories
For grounding we only recommend our special grounding accessories. Interior: Grounding set ESW in combination with grounding strap EB2. Exterior: Grounding set ESA.
Material Application
Area of applicationTypical application for interior and exterior walls and for ceilings. Floor space: Bulk laid floor coverÂings (carpets, laminat, etc.) can be laid directly onto the shielding paint. Pay attention, that the shielding paint is not damaged! In case of glued floor coverings (carpets, cork, laminate, etc.) the shielding paint has to be aftertreated with a solvent free priming coat to improve the adheÂsion. We advise against bonding e.g. real-wood parquets, the adhesive tensile strength of the shielding paint is probably insufficient.
Interior approach
- Drill holes for ESW grounding plate.
- Ground-strap EB2 has to be applied uninterrupted in one piece through all painted surfaces, as stated in our grounding instructions sheet.
- Apply the shielding paint in one or two layers, depending on the favored shielding effectiveness. Apply second coat of shielding paint to the area where the grounding plate ESW will be mounted.
- Allow the paint 24 hours to dry.
- Fix the ESW grounding plate.
- More procedures see „Final coat“.
Exterior approach
- Level out the mounting surface for grounding plate ESA.
- Drill holes for the grounding plate ESA.
- Apply the shielding paint in one or two layers, depending on the favored shielding effectiveness. Apply second coat of shielding paint to the area where the grounding plate ESA will be mounted.
- Allow the paint 24 hours to dry.
- Fix the ESA grounding plate and glue the top cover.
- More procedures see „Final coat“.
Application temperature
Minimum application temperature: +5°C / 41°F. This temperature applies also for the drying time!
Underground
Excellent adhesion on various undergrounds like existing emulsion paints, sheetrock, wallÂpaper, cement, plaster, masonry, wood, etc. Always consider: The underground needs to be solid, clean, degreased and dry. Absorbent or porous surfaces must be prepared with a primer. Old coats of paint or old wallpapers which can be etched by water, should be removed.
Preparation
The conductive particles deposit on the bottom of the paint container after a prolonged storage. There-fore shake the paint container well or mix it thoroughly with an electrical paint stirrer.
Compatibility
The shielding paint is ready for use. Never mix with water or other coating materials!
Application
- Use a first-class paint roller with a pile height of 10-13 mm.
- Limited usable are lacquer-rollers, foam-rollers or brushes, the coating layer often gets too thin for a good attenuation!
- To achieve a constant high attenuation, it is essential to apply the shielding paint with equal thickness; do not skip areas! Always soak the paint roller with the equal amount of paint and try to coat equal surfaces!
- The pigmentation size is under 200 μm, spraying with airless equipment is possible with bigger nozzles.
- Allow to dry for 24 hours.
Final coat
To protect the soft/viscoplastic surface of this shielding paint against mechanical damage and humidity, we recommend two top coats:
Interior: With high-quality, good covering, plastic bonded dispersion emulsion paints or dispersion silicate paints (e.g. KEIM Biosil, Ecosil, Optil). Natural resin paints are usable with some limitations. Alternatively paste over with wallÂpapers, glass fabrics, etc.
Exterior: With high-quality , good covering, highly hydrophobic dispersion emulsion paints or silicon resin paints.
Under plaster: Due to an adhesive tensile strenght of 1.9 N/mm² in conformity with ETAG 004 for EIFS-systems (stipulates minimal 0.08 N/mm²), this shielding paint is also usable directly under pure plastic bonded plaster. Never use mineral plasters, no adhesion!
Never use: Pure mineral bonded coatings with clay, loam, chalk or silicate adhere very bad on this shielding paint, they should never be used!
Consumption
The consumption depends on the character and absorbency of the underground. Typical interior productiveness: 7.5 m²/l. Typical exterior producÂtiveness: 5 m²/l. Rule: the higher the consumption, the better the attenuation.
