Super Shield Silver Conductive Coating (842)

We are one of the leading Suppliers of Super Shield Silver Conductive Coating (842) in Maharashtra, India. The 842 Silver Conductive Coating is a highly conductive acrylic paint, which is designed to reduce the electromagnetic or radio frequency interference (EMI/RFI). Long-term protection from EMI/RFI is assured by its durable acrylic resin that minimizes the loss of metallization through rubbing and by the oxidation resistant silver that slows down the conductivity degradation with age. The flake shape helps to ensure the maximum points of contact, to ensure a better conductivity. In addition, the 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.

Features :

• High Conductivity (15 Siemen)Low Surface resistance of ‰¤0.066 Ω/sq for a 1 mil coat
• Tough and durable coating
• Rub off resistant
• Corrosion resistant coating
• Stronger adhesion than water based coatings
• Low VOC's
• Median attenuation 75 dB ±20 dB per 25.4 ¼m (~1.0 mil) for frequency range of 10 MHz to 18 GHz

Applications & Usages :

• Its primary application is to provide an excellent conductivity EMI/RFI shielding suitable for harsh environments. It may also act as a conductive base for applications where it is necessary to impart the highest degree of conductivity to a surface. As well, the silver is non-magnetic, offering a low relative permeability that provides reasonable skin depths, which makes it suitable for microwave transmissions applications.

Compatibility:

• Chemical The silver filler is quite resistant to oxidation, except in environments that contain contaminants like H2S or ozone, which tarnish its surface. Unlike many other metal oxides, silver oxide remains conductive so degradation due to oxidation.
• The thermoplastic resin is dissolved by common paint solvents like toluene, xylene, acetone, and MEK. This allows great coating repair and work characteristics, but it does make the coating unsuitable for solvent rich environments.
• Adhesion - The 842 coating adheres to most plastics used to house printed circuit assemblies; however, it is not compatible with contaminants like water, oil, and greasy flux residues that may affect adhesion. If contamination is present, clean the surface to be coated first.
