摘要
The present invention relates to new substance combinations as vapor phase corrosion inhibitors for protecting a broad range of customary utility metals, including iron, chromium, nickel, tin, zinc, aluminum, copper, magnesium and their alloys, against corrosion in humid climates. Said substance combinations comprise (1) at least one C6 to C10 aliphatic monocarboxylic acid, (2) at least one C6 to C10 aliphatic dicarboxylic acid, and (3) a primary aromatic amide. Preferably they further comprise (4) an aliphatic ester of hydroxybenzoic acid, in particular of 4-hydroxybenzoic acid, and/or (5) a bemzimidazole, in particular a benzimidazole substituted on the benzene ring.
