FIELD: chemical technology. SUBSTANCE: method is based on utilization of depleted iron-chrome catalyst in ammonia production. Method involves grinding to dispersity 50 mcm, not above, followed by product wearing in medium of organic solvent. Coating indices based on polystyrene varnish containing 20-40% proposed pigment: covering power is 160-316 g/$$$, resistance to atmosphere corrosion - marks, high parameters of adhesion and film bending. EFFECT: enhanced quality of coating. 1 tbl
