Marble together with the zinc phosphate pigment creates an effective inhibiting composition for protection of steel in slightly acidic environments. Charge transfer resistance of steel increases by 5-10 times under the influence of extract of the inhibiting composition. Filling of polyurethane primer by the inhibiting mixture reduces under film corrosion and ensures adhesion stability of polyurethane coatings in areas of pipelines welds and other constructions.
