Customer Value Proposition:
CHO-SHIELD 596 is a two component, silver filled, conductive epoxy paint formulated to provide EMI shielding and electrical grounding on plastic and composite substrates. It is a great material choice for chemical resistant plastics or other hard to adhere to substrates. In addition, CHO-SHIELD 596 may be used to provide a compatible conductive metal coating for mating silver filled EMI shielding gaskets to aluminum flanges. By forming a barrier over the aluminum substrate this silver epoxy coating reduces the overall galvanic corrosion of the EMI gasket/ aluminum flange system. CHO-SHIELD 596 demonstrates exceptional environmental stability, maintaining electrical conductivity, adhesion, and abrasion resistance when subjected to high and low temperature extremes, high humidity, and salt fog corrosion environments. Typical applications include military and commercial electronic enclosures, missile canisters, man portable electronics, radar systems, avionic boxes, engines, and aluminum flanges and structures.
