Silver/Copper Shielding A silver plated copper shielding coating designed to give low resistance even in thin layers on plastic electronic housing. Fast drying, touch dry after 5 mins, maximum conductivity after 24 hrsExcellent surface resistivity (0.3 to 0.77 per sq. at 50 microns)Superior scratch resistance and excellent environmental ageing abilityTypical attenuation 75dB at 50 micron coating thicknessSome substrates e.g. polypropylene may require a suitable primerWarning Flammable.
