Innovative VCI anti-corrosion solutions to protect ferrous and non-ferrous metals during storage and industrial shipments
Corrosion represents one of the main challenges for companies that produce, store and transport metallic components. The damage caused by oxidation can irreparably compromise product quality, generating high costs for replacements, complaints and loss of corporate reputation.
The PROPATECH VCI (Volatile Corrosion Inhibitor) system by Propagroup is the most advanced and effective solution for anti-corrosive protection of metals. Thanks to volatile corrosion inhibitor technology, our products create an invisible protective barrier that preserves steel, aluminum and other metallic materials from corrosion and oxidation. The result is complete, clean and safe protection that eliminates the need for traditional oils and greases, ensuring ready-to-use products and maximum end-customer satisfaction.
Problems solved and VCI application sectors
PROPATECH VCI anti-corrosion products effectively solve corrosion and oxidation problems that affect numerous industrial sectors. From automotive to mechanical industry, to various sectors dealing with metal and mechanical parts that need protection during transport and storage.
Applications range from the protection of small metal parts in small containers to the preservation of large industrial structures. Particularly effective for steel and ferrous and non-ferrous materials, VCI systems are used in warehouses, maritime containers and environments with high humidity, where traditional methods are insufficient or impractical.
Competitive advantages of VCI anti-corrosion technology
The adoption of the PROPATECH VCI system brings significant economic and operational advantages compared to traditional anticorrosive methods. The complete elimination of protective oils and greases drastically reduces pre-use cleaning costs, while the absence of residues ensures products are immediately ready for installation or processing.
Thanks to the various product types in the PROPATECH VCI product range, it is possible to achieve uniform protection even in hard-to-reach areas, eliminating the risk of localized corrosion typical of surface treatments. The reduction in oxidation damage claims and increased end-customer satisfaction translates into a significant return on investment and strengthened company reputation, all without compromising environmental and operator safety.
The PROPATECH VCI system: excellence in metal protection
The PROPATECH VCI anti-corrosion system is the result of decades of research and represents an innovative solution for protecting metals from corrosion during shipping and storage. Developed through continuous research in the industry's most advanced laboratories, this volatile corrosion inhibitor offers a safe and convenient method for preserving metal products. The range includes VCI papers, polymeric films, diffusers and sponges, designed to meet the needs of the world's most demanding manufacturing industries.
The operating principle of VCI (Volatile Corrosion Inhibitor) is based on a well-defined three-phase process. During sublimation, VCI molecules pass from solid to gaseous state starting from the protective material. Subsequently, through diffusion, these molecules distribute uniformly throughout the packaging creating a protective environment. Finally, in the adsorption phase, VCI molecules deposit on the metal surface forming an invisible protective layer that neutralizes corrosive agents such as water vapor, saline atmosphere, sulfurous gases and industrial pollutants present in the air.
The advantages of the PROPATECH VCI anti-corrosive system are multiple and significant for companies that need to protect their metal products. The system is particularly safe as it contains no harmful substances such as nitrites, secondary amines, aromatic amines or heavy metals. Its simplicity of integration into existing production processes makes it extremely practical, while the characteristic of being clean allows it to replace traditional oiling and greasing systems, which are notoriously impractical and polluting. Treated products are immediately ready for assembly, eliminating cleaning time from oils and greases.
The use of VCI for anti-corrosive protection requires some simple precautions to achieve optimal results. Metal parts must be clean, dry and free of residues before application. Packaging with VCI film or paper must be made without holes or air passages, avoiding contact with materials that could contain water or acids. It is important to complete the operation within 12 hours and allow the active substance to completely saturate the packaging before shipping. For particular situations, complementary desiccant products can be used to prevent condensation formation inside the packaging.
VCI films and plastic materials for advanced protection
The anticorrosive plastic materials PROPATECH VCI represent an effective and versatile solution for protecting metal components of various sizes and shapes. VCI plastic films combine the barrier properties of polymers with the protective action of volatile inhibitors, offering dual protection against moisture and corrosion, especially when combined with Propasec desiccants.
These plastic materials stand out for their ease of application and ability to adapt to complex geometries, ensuring uniform protection even on irregular surfaces. Available in different weights and formats, from thermoformed bags to film rolls for automatic lines, VCI plastics maintain their protective properties unchanged for extended periods. Their transparency allows immediate identification of protected components, while mechanical resistance ensures integrity during handling and transport.
VCI emitters and diffusers: controlled environmental protection
The anticorrosive emitters and diffusers PROPATECH VCI are devices designed to release volatile corrosion inhibitors in a controlled manner in closed or semi-closed environments. These systems ensure optimal concentration of VCI active ingredients in the surrounding atmosphere, creating a protective microclimate for all metallic components present.
VCI diffusers are particularly effective inside packaging, storage containers, electrical cabinets and other closed environments where protection must be maintained constant over time. Their action is completely automatic and requires no maintenance interventions, guaranteeing long-term protection. The emitters are available in different types, allowing protection of volumes of various sizes, with precise control of the duration and intensity of protection.
