Kohesi Bond KB-SS-SIL is a silver filled, sodium silicate based coating system. Firstly, this product offers phenomenal electrical conductivity. This products offers the highest level of shielding towards electromagnetic interference (EMI) and radio frequency interference (RFI). Shielding effectiveness is extremely critical for electronic devices, since energy from various appliances such as radios can interfere with their performance. Our conductive coatings are usually applied to housing substrates to protect the devices from any such interference. Shielding effectiveness is measured by attenuation, which refers to the difference in an electromagnetic signal’s intensity before and after shielding. The unit of measurement is in decibels (dB).
