Conductive Sodium Silicate is available for EMI/RFI shielding.

Press Release Summary:



Formulated for applications where EMI/RFI shielding is required, aqueous-based MB600S can be brushed or sprayed with proper equipment, will cure at room temperature in 24–48 hr or in 1–2 hr at 80°C, and has 0 to +700°F service range. Silver gray colored conductive coating, tested to IEEE 299, 2006 methods, exhibits effectiveness of 95–105 dB from 100 MHz to 2 GHz. Above 2 GHz, shielding effectiveness decreases to 80 dB and slightly below. Above 4 GHz, effectiveness is 60–70 dB.



Original Press Release:



New Silver Conductive, One Part Aqueous Based Sodium Silicate System Available for EMI/RFI Shielding



Master Bond MB600S is an aqueous based sodium silicate formulated for coating applications where electromagnetic interference/radio frequency interference (EMI/RFI) shielding is required.



The energy emitted from various sources, including radios and appliances, can interfere with other electronic devices. Conductive coatings are often applied to the housings in order to protect the devices from these types of interferences. This silver gray colored system is used in a variety of aerospace and electronic applications.



Tested according to IEEE 299, 2006 methods, MB600S was as effective as the aluminum reference with a range of 95-105 dB, from 100 MHz to 2 GHz. Above 2 GHz, the shielding effectiveness of MB600S decreased to 80 dB and slightly below. Above 4 GHz, the effectiveness was 60-70 dB.



As the system is water based, it is relatively non-toxic and easy to handle. It can be brushed or sprayed with the proper equipment. If sprayed, the shielding effectiveness would be even greater than the values given above.



MB600S will cure at room temperature in 24-48 hours or in 1-2 hours at 80°C. It features high temperature resistance with a service temperature range of 0°F to 700°F. The compound is available in glass jars, and has a shelf life of 6 months in original, unopened containers at room temperature.
