Preliminary estimation of effectiveness of the polyethylene film made on the basis of volatile IFHAN-112 rust inhibitor (3 and 4.5% of masses) is carried out for protection against atmospheric corrosion of carbon steel St3, copper M1, zinc Ts0 and aluminum D16 alloy by results of a field tests in the conditions of the humid tropical climate of the Southern Vietnam (MNIIS, Dam Bay) within 12 months. The contact method (3.0 and 4.5% of IFHAN-112) provides
the almost complete protection of steel St3 within 6…12 months of a natural exposition, while vapor-phase protection does only within 6 months. Vapor and contact methods provide high degree of protection copper М1 and zinc Ts0 in 6…12 months of exposure and significantly inhibit corrosion of D16, but does not provide full protection of the alloy.
