MG Super Shield Silver Conductive Coating Spray
MG Chemicals Part Number: 843AR-340G
This product is also available in liquid form and larger aerosol cans by special order through Vetco.
Reduce or eliminate EMI / RFI interference with this easy to apply conductive silver coated copper spray!
This spray is an effective EMI/RFI shielding paint for use on plastic electronics enclosures. Consists of a tough, durable acrylic base pigmented with a high purity silver coated copper flake.
Features:
Applications & Uses:
The 843 Silver Coated Copper Conductive Coating is a highly conductive acrylic paint designed to reduce electromagnetic or radio frequency interference (EMI/RFI). Long-term protection from EMI/RFI is assured by its durable acrylic resin that minimizes loss of metallization through rubbing, and by the oxidation resistant silver that slows down conductivity degradation with age. In addition, loss of shielding through paint peeling is unlikely since the acrylic resin system was shown, in UL related testing, to adhere to even difficult substrates like ABS and polycarbonates.
