Corrosion fluids of brown color containing additive of absorbing corrosion inhibitors. They do not cause so-called contact corrosion. They will stop further corrosion if they are used on corroded places, so-called stop-effect. Relative protective performance Ur (%) 30 days, in % of vol. 97-100.

Conservation oils of 200 series are petroleum oils of yellow color with additive of complex corrosion inhibitor. They have ability to displace water from metallic surfaces and efficiently neutralize finger prints. They can be applied easily and form very thin homogenous oil film (2-10 μm) with excellent

Modern conceived water-soluble agents, they are mixtures of suitable inhibitors of corrosion and water. After water evaporation, thin dry protective layer remains on the surface of conservation material. Agents of 400 set do not contain petroleum hydrocarbons and they are well biologically
