MB600S aqueous-based sodium silicate coating is said to provide electromagnetic interference/radio frequency interference (EMI/RFI) shielding. Is effective as aluminum reference with a range of 95-105 dB, from 100 MHz to 2 GHz, per IEEE 299, 2006 methods. Above 2 GHz, shielding effectiveness decreases to 80 dB and slightly below. Above 4 GHz, effectiveness is 60-70 dB. Is relatively non-toxic and easy to handle. Can be brushed or sprayed on. Cures at room temperature in 24 to 48 hr. or in 1 to 2 hr. at 80°C. Service temperature range 0° to 700°F.
