EMI Shielding Caulk Delivers Superior Performance in Military Radar Systems
Shielding for electromagnetic interference (EMI) is critical to military electronics systems operating in demanding environments requiring low emitted electronic signatures and protection from electromagnetic radiation. In mobile military applications, EMI shielding must be maintained during storage, transport and operation in a wide variety of demanding and corrosive environments.
An integral part of the EMI shielding system is an EMI shielding caulk that seals the seams on external structures from panel to panel to ensure conductivity around the entire system. The caulking maintains a faraday cage that protects the internal electronic components against external electromagnetic interference and/or electromagnetic pulses (EMP). This prevents a possible failure mode of the EMI shielding enclosure when two metal panels are joined together without protecting the seam with a reliable caulking. If there is no caulking or if an inferior caulking fails, there is a significant opportunity for EMI emissions/susceptibility.
Parker Chomerics developed the next generation EMI shielding caulk for use on military radar shelters. The CHO-BOND® 1019 provides a substantial increase in performance over existing legacy materials by improving EMI shielding performance, corrosion resistance and by reducing application time. In addition, the new CHO-BOND® 1019 is paintable, eliminating the need for expensive intermediate layers. Along with better shielding performance, these features translate to significant savings by reducing manufacturing and material cost, increasing throughput, increasing the working life of the shelter and reducing maintenance costs.
