Cortec Corrosorber® VpCI® Paper

Cortec Corrosorber VpCI Paper is a specially designed packaging paper that not only absorbs corrosive gases but also releases powerful VpCI (Vapor phase Corrosion Inhibitor) molecules to protect precious metals from tarnishing and corrosion. It's like a two-in-one superhero for your valuable items, actively neutralising harmful airborne elements while creating an invisible shield directly on the metal's surface.

Unlike standard anti-tarnish papers that might only offer a barrier, Cortec Corrosorber VpCI Paper actively scavenges corrosive gases like hydrogen sulfide (H2S) from the atmosphere, and crucially, it won't re-release them. Furthermore, it incorporates VpCI technology, which means it doesn't just block moisture like a desiccant; it releases protective vapours that form a molecular layer on the metal itself, offering a much more comprehensive and active form of corrosion inhibition.

Absolutely! One side of the Corrosorber VpCI Paper has a clever coating that changes colour. It starts as a light green, and as it absorbs hydrogen sulfide gas and reaches saturation, it gradually darkens. This visual cue is super helpful because it lets you know exactly when the paper has done its job and needs to be replaced, ensuring continuous, effective protection.

This fantastic paper is specifically engineered to safeguard precious metals such as silver, gold, and tin from tarnishing. It's also highly effective for protecting other metals like copper, brass, iron alloys, and aluminum alloys, making it incredibly versatile for a range of applications.

Yes, it is! Cortec Corrosorber VpCI Paper is non-toxic and designed to be safe for handling without requiring special safety equipment. It also doesn't contain heavy metals, nitrites, chromates, or phosphates, which makes it an environmentally responsible choice for your packaging needs.

When wrapping, it's really important to ensure the white side of the paper is placed directly against the surface of the metal you want to protect. The reverse, green side is the one that's designed to absorb impurities from the surrounding environment, keeping them away from your valuable items.

For the best results, your metal products should be completely dry and free from any remaining water or moisture before you wrap them. While the VpCI technology works wonders, starting with a clean, dry surface helps ensure maximum efficacy of the corrosion inhibitors.

Absolutely! This paper is incredibly flexible. You can use it as a sheet liner for cargo containers, or even insert strips between hollow regions of larger packages. It's also perfect for interleaving between multiple items, preventing direct contact and offering individual protection.

For the VpCI molecules to effectively vaporize and form their protective layer, it's best to place the Corrosorber VpCI Paper as close to the metal's surface as possible. There shouldn't be any physical barrier between the paper and the metal itself.

While it's not always about a hermetic seal, folding the edges of the paper together to prevent free airflow around the wrapped item significantly enhances the protective environment. This helps to contain the VpCI vapours and the absorbed gases, ensuring a more consistent and long-lasting protective barrier.

Yes, it's ideal for sensitive items like electrical parts and control systems. The VpCI molecules don't interfere with the conductivity or surface resistivity of metals, meaning your electronics will be protected without compromising their functionality.

During both transportation and long-term storage, the VpCI vapours emitted from the paper constantly re-deposit a protective molecular layer on all exposed metal surfaces. This dynamic protection ensures that even if the packaging is briefly opened, the barrier quickly self-replenishes, safeguarding your items from moisture, H2S, SO2, and other corrosive elements.

Absolutely, it's perfect for jewellery and other finished products made from precious metals. It helps prevent tarnishing and keeps them looking pristine, eliminating the need for messy coatings or post-packaging cleaning.

This paper is designed to offer robust protection for up to two years, or until the colour-change indicator on the green side signals that it has reached its saturation point. This gives you ample time for both storage and transit.

One of the brilliant features of VpCI technology is that the protective molecular layer is invisible and does not need to be removed. Your metal items will be dry and ready for immediate use, processing, or further assembly straight out of the packaging, saving you time and labour.

It's specifically formulated to be effective even in aggressive environments. The combination of its H2S absorption capabilities and the VpCI technology means it provides excellent defence against high humidity, sulfur dioxide (SO2), and the tarnishing effects of hydrogen sulfide.

No, not at all! The VpCI molecules form an incredibly thin, invisible layer on the metal surface that doesn't interfere with physical properties like conductivity or surface resistivity. Your metals will retain their original appearance and characteristics.

When stored in its original packaging, indoors, away from direct sunlight, and within the recommended temperature range of 40-100 °F (4-38 °C), Cortec Corrosorber VpCI Paper has a shelf life of two years.

Yes, it's designed to protect against galvanic corrosion, which occurs when two different metals are in contact in the presence of an electrolyte. The VpCI layer acts as a barrier, preventing this kind of corrosive interaction.

The product is typically available in a 40 lb basis weight, offering a good balance of protection and flexibility for various packaging needs.

Absolutely, it does! The beauty of Corrosorber VpCI Paper is that it provides both tarnish prevention and packaging in a single, streamlined step. This means you can say goodbye to the hassle and expense of applying and then later removing traditional coatings or using tarnish removers.

You can usually get Cortec Corrosorber VpCI Paper in both standard and custom-sized rolls and sheets, giving you flexibility to suit your specific packaging requirements.

By combining active protection, gas absorption, and a visible indicator into one simple-to-use paper, it streamlines your packaging process and extends the life of your valuable assets. This often translates to significant cost savings by reducing rework, scrap, and the need for additional protective materials or cleaning steps.

Since Corrosorber VpCI Paper contains no silicones, nitrites, chromates, phosphates, or other heavy metals, it promotes a safer working environment. Workers can handle it without concerns about exposure to hazardous chemicals, making it a more pleasant and secure option.

Yes, its simple wrap-and-fold application means it integrates seamlessly into most existing packaging operations. There are no complex systems to maintain or specific concentrations to calculate, making it very user-friendly.

Yes, the VpCI protection is "self-replenishing." This means that even if the package is briefly opened, the VpCI molecules will continue to emit and re-adsorb onto the metal surfaces, maintaining the protective layer and ensuring continuous corrosion inhibition.

It's excellent for both. For short-term needs like in-plant processing or shipment, it provides immediate, clean protection. For longer-term storage, its multi-year protection capabilities make it a reliable choice for preserving valuable assets.

While its primary strength lies in H2S absorption, the VpCI technology also helps to mitigate the effects of other corrosive atmospheric elements like sulfur dioxide (SO2) and general humidity, contributing to a more protected environment for your metals.

For detailed technical specifications and safety information, you can always refer to the Product Data Sheet (PDS) and Material Safety Data Sheet (MSDS) which are typically available from the manufacturer or authorised distributors like Valdamark Direct.

Beyond wrapping, you could consider using it as interleaving material when stacking metal sheets or parts, as a liner for storage drawers containing sensitive instruments, or even cut into smaller pieces and placed within tight enclosures of machinery or electrical panels to target specific areas prone to corrosion. Its adaptability truly makes it a versatile tool for corrosion prevention.
