This is a sprayable, brushable, or rollable conductive metallic coating using a specially formulated copper as the conductive agent for superior performance in electric field and RF shielding. Developed initially as an RFI/EMI shield for plastic electronic equipment housings, it can be applied directly onto acrylic, ABS and structural foams, as well as solvent sensitive materials such as polycarbonate and polystyrene. Create your own Faraday Cage with this reflective wifi blocking paint. Can also be applied to other non-porous surfaces including primed wallboard, wood and clean metals. Sometimes called the guitar shielding paint its great to provide a conductive surface to help eliminate EMI interference. Can be applied by sprayer, brush or roller just like ordinary latex paint! Just as safe to handle, too. Thin with water. Good surface resistivity of <5 Ohm/sq at 1 mil dry film thickness. Attenuation: more than 75 dB from 30 MHz to 1.5 GHz. Dried coating is stable up to 250° F. Covers 670 ft² per gallon per mil thickness if application is 100% efficient (typically 400 ft² per gallon when applied by roller). Color = Glitter Copper, but you can paint over with ordinary latex paint to achieve desired aesthetics. Warning: CuPro-Cote liquid does not tolerate freeze/thaw well. We cannot be responsible for freeze damage during shipping. Click to see SDS (.pdf) RoHS Compliant. VOC: 1.0 ± 0.1 lbs/gallon (120.0 ± 12 grams/liter) If you are concerned about reflections inside the painted shield, line a portion of it with Microwave Absorber Sheet. Requires grounding like any other RF shielding material.
