Y-SHIELD Indoor/Outdoor PaintHigh Frequency Shielding Paint
This is a water-based paint for shielding interior or exterior surfaces from radio frequency and microwave radiation up to 18 GHz (see graph below), reducing RF/MW by 99.99% (40 dB) with one layer. With a pure acrylic binder, it adheres well to masonry, cement, plaster, construction board, polystyrene, latex paint, and many other surfaces, is frost-resistant, dries quickly, cleans up with water, and comes ready to use.
The surface of this paint is highly conductive (about 10 ohms per square), and attenuation is consistent no matter what the polarization of the signals because of its holohedral carbon structure, without fibers or meshes. About 10% of the shielding is accomplished through the carbon’s good RF dissipation, which reduces reflections from both outside and inside the area to be shielded. It does need to be grounded.
It’s RoHS compliant, comes in black only, covers 50 to 100 square feet (5 to 10 square meters) per liter, and can be covered with latex paint, wallpaper, etc. It has a shelf life (unopened) of 15 months.
The minimum temperature for applying it is 1°C (33.8°F), and it can be shipped in the winter or any other season. It weighs 3.2 pounds per liter.
