Anti-corrosion Materials
VpCIs are vapour phase corrosion inhibitors that form a molecular layer on the surfaces of ferrous and non-ferrous metals and thus provide reliable protection against the corrosive effects of humidity, SO2 and H2S.
The corrosion inhibitors provide temporary corrosion protection, do not change the structure or properties of the material, and after the VpCI package or other source is removed they will volatilize from the protected surface and the protected part can be further finished in any way or used with no change.
- Volatile particles migrate to all hardly accessible areas and cavities.
- VpCIs are active for at least 24 months. By sealing the package properly effective protection for up to 5 years can be achieved.
Unique solutions for all types of corrosion protection.
TART, s.r.o. has met demanding license conditions and became the exclusive manufacturer of CORTEC® VpCI products in the Czech Republic. Thanks to this it brings state-of-the-art technologies from the world´s most important company in the corrosion protection branch to the Czech market.
The primary item in the Cortec system is anti-corrosion packaging materials that cover the widest range of metal working industry´s needs. Our assortment also includes curing agents; cleaners and degreasers; rust removers; corrosion inhibiting additives for water-based or solvent-based fluids; corrosion inhibiting additives for elastomers; corrosion inhibiting cutting emulsions; permanent, temporary or transport anti-corrosion coatings; and migratory corrosion inhibitors for reinforced-concrete structures.
Cortec Corporation´s products can provide long-term, medium-term or long-term corrosion protection to your products. The company has developed an entirely new generation of volatile corrosion inhibitors (VCI), the so-called VpCI (Vapor phase Corrosion Inhibitor). The uniqueness of this new technology consists in the increased pressure of inhibitors which expulses water and air molecules from the surface of the product packaged.
Benefits of protection by means of CORTEC® VpCI corrosion control system:
- High performance.
- Easy to apply (also on hardly accessible areas).
- Reusable in case of anti-corrosion packages, especially anti-corrosion PE films.
- CORTEC® VpCI products are recyclable and have an ISO 14001 environmental certificate.
- Safe for human health - non-toxic, do not contain any heavy metals, nitrides, silicones, phosphates, and chlorohydrocarbons.
Using VpCI (VCI) anti-corrosion packages eliminates many process steps:
- There is no need to preserve with oils, greases, and waxes and then degrease, clean, blast or renew the surface refinish.
- No consumption of cleaners and solvents.
- No hazardous waste disposal.

Curring Agents
CORTEC curing systems protect metal surfaces against corrosive attacks not only by creating a barrier preventing oxygen and corrosive substances access, but also by active acting of VpCI (VCI) corrosion inhibitors contained in these agents. They provide the effective protection of external and internal surfaces and mechanical parts during storage, shut-downs, and operation. Protective barrier products are water-, oil-, or solvent-based and can form many types of protection surfaces. By combining these products and VpCI-126 anti-corrosion film you will achieve a very effective solution of the corrosion protection of a material and its package.
