PURPOSE: Provided is an electro magnetic shielding, inorganic coating composition for use as exterior materials of building, which shows increased electro magnetic shielding efficiency by using a mixture of carbonaceous powder and magnetite powder as a conductive material. CONSTITUTION: The electro magnetic shielding composition comprising a conductive material, a binder, a filler, a compounding agent, a resin, and an admixture, is characterized in that the conductive material is a mixture of carbon powder having a particle size of 0.1-1.0 mm and a magnetite powder having a particle size of 10 micrometer to 0.5 mm and a ratio of thickness to diameter of 10-50, in a mixing ratio of 1:0.5-20, and the amount of the conductive material is 5-50 parts by weight with respect to 100 parts by weight of binder. |
