Master Bond MB600SCN is an aqueous based, sodium silicate system with a silver coated nickel filler. It is intended for use in applications where very good shielding effectiveness is required and cost considerations might be more pronounced. Electromagnetic interference (EMI) and radio frequency interference (RFI) are very important factors in electronic applications. The energy emitted from various sources such as radios, appliances, etc. can interfere with other electronic devices that are made from plastics.
