Test of "shielding paints" to shield electrosmog

Welcome! Why does this page exist? A lot of people are suffering from the technical radiation of cell towers or cordless phones, as to say from high frequence electro-magnetic fields. To protect yourself, a lot of solutions are offered. In the field of physically measurable shielding products the amount of shielding paints is permanently increasing. As there are more and more products in the market and producers‘ information about the attenuation often are either exagerated or completely wrong, we tested all currently available shielding paints. Technical datas (attenuation, adhesive tensile strength, moisture resistance, etc.) are strictly determined to common standards.

The green products represent the winners of our practical and measurement tests. If you are a manufacturer and do not agree with our result of the shielding attenuation, we gladly advise you how to make a professional measurement, feel free to write us an email.

(1) The shielding attenuation is the most important criterion for shielding paints. Tested according to ASTM D 4935-10 with a R&S ZNB40 from 40 MHz to 40 GHz and TEM-cells. The higher this value of dB the better.
(2) Only by comparing „price / dB-shielding“ you can compare products with different shieldings values. The lower the price, the better.
(3) The adhesive tensil strength describes how strong the paint adheres to the surface. Measured according to ASTM C1583/D4541/D7234/D7522 with DeFelsco Positest AT-A. The higher this value, the better.
(4) How strong is the resistance rising / is the attenuation falling by moisture? Very important for outdoor usage and overpainting. The lower this value, the better.
(5) A proper grounding is very important to avoid that low frequency electric fields will to dock on the shielding paint. It is not good when grounding accessories are not available.
