ABSTRACT:
A pigment system for electronic and electromagnetic shielding coatings including in percent by weight about 30% to about 70% of a nickel powder produced by decomposition of nickel carbonyl under conditions to provide a powder having a chain-like structure of irregularly shaped particles with an average particle size in the range of about 2 to 4 micrometers (um) and a specific surface area of at least about 0.5 m.sup.2 /g, about 20% to about 60% zinc dust and up to about 40% of an iron-nickel powder produced by codeposition from nickel and iron carbonyl with the proviso that the percentage of nickel powder plus the percentage of nickel-iron powder must be in excess of about 45%.
