Cortec Cor-Pak® Tablets Superior VpCI® / VCI Tablets

Cor-Pak VCI Tablets are a super efficient dry method for protecting metals within an enclosed package from corrosion. They use a clever technology called Vapor phase Corrosion Inhibitor (VpCI), where tiny molecules vaporize from the tablet and create an invisible, protective layer over all metal surfaces, even those hard-to-reach spots. This layer acts as a shield against moisture and other corrosive elements, stopping rust before it even starts.

Absolutely! Cor-Pak VCI Tablets are designed to provide broad-spectrum protection for a wide array of metals. This includes both ferrous metals like carbon steel and stainless steel, as well as non-ferrous metals such as aluminum, copper, brass, and even silver and solder. It's a truly versatile solution for multi-metal protection.

When used correctly in a sealed environment, Cor-Pak VCI Tablets can provide robust corrosion protection for an impressive duration, typically up to 24 months. This long-lasting protection makes them ideal for items that need to be stored or shipped for extended periods.

Each individual Cor-Pak VCI Tablet is quite potent, capable of protecting approximately 0.25 cubic feet (or about 7.1 liters) of enclosed space. This specific sizing allows for precise dosing depending on the size of your packaging.

That's one of the fantastic benefits of Cor-Pak VCI Tablets – no, you don't! There's no need for any messy cleaning, degreasing, spraying, or wiping of your metal surfaces beforehand. You simply place the tablets and seal your package, saving you valuable time and effort.

• Cortec VpCI-417 Heavy Duty Cleaner/Degreaser
• Cortec VpCI-419 Heavy Duty Degreaser Cleaner

Yes, they're incredibly adaptable! Cor-Pak VCI Tablets are perfect for use with a variety of packaging materials. This includes common options like corrugated cardboard boxes, various plastic wraps and bags, foil bags, and even more rigid containers made of metal, plastic, or wood.

While it's not overly complicated, the key is to ensure they are inserted into the enclosed space and the package is then sealed promptly. You can insert them manually by hand or, for larger scale operations, they are also suitable for automated dispensing systems, making the process efficient for any volume.

For average or temperate environmental conditions, one tablet per 0.25 cubic feet (7.1 liters) is sufficient. However, if your items are facing more aggressive environments – perhaps high humidity, temperature fluctuations, or corrosive atmospheres – it's recommended to double up and use two tablets for every 0.25 cubic feet of enclosed space to ensure maximum protection.

Not at all, which is a significant advantage! The VpCI protective layer is self-replenishing. If you momentarily open the package and disturb the layer, the VpCI vapors will continuously regenerate and re-establish the protective coating once the enclosure is sealed again, providing ongoing protection.

One of the greatest conveniences of Cor-Pak VCI Tablets is that the protective layer does not need to be removed. Your components, parts, and assemblies are ready for immediate use straight out of the package, with no cleaning or degreasing necessary. This streamlines your workflow and saves on labor.

They are especially convenient for small hardware. The compact size of the tablets makes them easy to insert into packaging containing nuts, bolts, screws, and other fasteners, ensuring that these small but crucial components remain free of rust.

They are considered a "dry method" because they don't involve applying messy oils, greases, or other wet coatings to your metal surfaces. The VpCI works by releasing an invisible vapor, which eliminates the need for any post-treatment cleaning or degreasing, saving you time and reducing labor costs.

Cor-Pak VCI Tablets offer distinct advantages over traditional methods. Unlike oils, they leave no residue and require no removal. Compared to desiccants which only absorb moisture, VpCI actively forms a protective layer against corrosion, even regenerating if disturbed. They provide a more comprehensive and convenient solution.

No, the protective VpCI layer is completely invisible and molecularly thin. It doesn't alter the appearance, dimensions, or any functional properties of the metal, meaning your products look and perform exactly as intended.
