CHO-SHIELD 579 Electrically Conductive Low Volatile Organic Content (VOC) Silver Epoxy EMI Coating
Brand: ChomericsParker Chomerics CHO-SHIELD® 579 EMI coating is a two-component, Ag filled conductive epoxy that adheres well to chemical resistant plastic and provides the added benefit of low volatile organic compounds (VOCs).
CHO-SHIELD® 579 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.
