ANTICORROSION PROPATECH VCI

VolatileCorrosionInhibitor

PROPATECH VCI volatile substances avoid corrosion (deterioration process of a metallic piece) caused by oxidation of the surface in contact with external environment.

PROPATECH VCI products, sublimating and diffusing inside the packaging, form a thin, invisible layer neutralizing the potential agents which cause metal corrosion, such as condensation, oxygen, brackish air, sulfurous gases and the most common industrial and environmental pollutants in the air.

Steps of VCI action

• Sublimation: the transformation from a solid to a gaseous state of VCI molecules starting from the protective material (paper, film, diffusers, foams, etc...)
• Diffusion: volatile distribution of VCI molecules into the packaging
• Adsorption: VCI molecules depositing on the metallic surface
