Parker Chomerics CHO-SHIELD® 596 EMI coating is a two-component, Ag filled conductive epoxy that adheres well to chemical resistant plastics and other hard to adhere to substrates. CHO-SHIELD® 596 is a silver-colored epoxy that provides an excellent moisture barrier as well as physical and chemical abrasion resistance. It is an ideal solution for mating silver-filled conductive elastomers to aluminum surfaces, significantly minimizing galvanic corrosion within the flange. It is also able to withstand extreme temperature fluctuations, high humidity, and salt fog corrosion environments while maintaining conductivity and adhesion. Features and Benefits:• Pre-measured kit allows for easy mixing of components• High EMI shielding properties (>90 dB) due to pure silver flake filler• Maintains electrical and mechanical stability in harsh environments due to epoxy polymer• Meets Military Spec MIL-C-22750• No primer required• Long pot life (8 hours) allows for application flexibilityTypical Applications:• Military Electronic Enclosures • Commercial Electronic Enclosures• Missile Cannisters• Man-portable Electronics• Radar Systems• Avionics Boxes• Engines• Aluminum Flanges and Structures
