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. Esoteric-products won’t help a lot. 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 often are either exagerated or wrong, we tested all currently available shielding paints. Technical datas (attenuation, adhesive tensil strength, moisture resistance, etc.) are strictly stuck to common norms. Processing in a direct comparison can be quite different: from unuseful to professional. The green products represent the winners of our practical and measurement–technology tests.

(1) The shielding attenuation is the most important criterion for shielding paints. Tested one-layer according to ASTM D 4935-10. 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 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.
