ECCOSHIELD® ES is a highly conductive surface coating that is a fine silver based lacquer and is sufficiently fluid enough that it will readily flow into cracks. However, ECCOSHIELD® ES will not fill gross voids at joints or seams; use a caulking compound such as ECCOSHIELD® VY product.
ECCOSHIELD® ES was specifically formulated for RF shielding applications and is often used to improve the RF integrity of metal housings or screen rooms. By applying ECCOSHIELD® ES to joints, seams and contacting surfaces, it is possible to convert a reasonably good metal structure to one of greater than 100 dB insertion loss from 15 kHz to 10 GHz. Metal to metal contact can be improved significantly as the coating fills slight irregularities and makes such intimate contact with exposed metal that even corroded joints can be made acceptable RF seals. When applied to a non-conductor, surface resistivity is substantially less than 1 ohm/square. Successive coats decrease surface resistivity even further. ECCOSHIELD® ES adheres well to metals, plastics, ceramics, wood, and concrete.
