Frequently Asked Questions
• What exactly is Cortec VpCI-337 19Ltr and what does it do?
Cortec VpCI-337 is a ready-to-use, water-based corrosion inhibitor designed for preserving internal void spaces. It's part of the Ecofog® range, utilizing Vapor Phase Corrosion Inhibitors (VpCI) that migrate and protect metal surfaces, essentially replacing older, more cumbersome metal preservation methods like nitrogen blanketing. This particular product comes in a convenient 19-liter pail, making it ideal for larger applications.
• How does Cortec VpCI-337 actually prevent rust and corrosion?
This innovative product works by releasing VpCI molecules into an enclosed space. These molecules travel through the air, even into hard-to-reach areas like crevices, and then condense onto all exposed metal surfaces. They form a very thin, self-healing protective film that acts as a barrier, preventing oxygen and other corrosive elements from interacting with the metal.
• Is Cortec VpCI-337 safe for different types of metals?
Absolutely! Cortec VpCI-337 is remarkably versatile and provides excellent corrosion protection for a wide range of metals. This includes both ferrous metals like hot-rolled steel, cold-rolled steel, stainless steel, and cast iron, as well as non-ferrous metals such as aluminum, copper, brass, zinc, and even plated steels and tinplate.
• What's the main advantage of using a vapor phase corrosion inhibitor like VpCI-337 over traditional rust preventatives?
The key advantage lies in its unique vapor phase action. Unlike traditional liquid or greasy rust preventatives that require direct contact and often messy application and removal, VpCI-337's molecules travel through the air to protect all surfaces within an enclosed space, even those that are difficult or impossible to reach manually. This significantly reduces labor, cleanup, and overall operational costs.
• Is Cortec VpCI-337 considered an environmentally friendly product?
Yes, it certainly is! Cortec VpCI-337 is a water-based, biodegradable formula. It boasts over 87% biodegradation within just 28 days, making it a much more environmentally responsible choice compared to many traditional oil-based or solvent-based corrosion inhibitors. Plus, the EcoAir® aerosol versions, if used, are powered by compressed air, eliminating harmful propellants.

Application & Usage: How to Get the Best Protection
• How do I apply Cortec VpCI-337 effectively in a large void space, like a tank or container?
For large void spaces such as tanks, containers, or export crates, Cortec VpCI-337 is typically applied by fogging or misting. The recommended application rate is approximately 1 liter per cubic meter (or 1 ounce per cubic foot) of enclosed space. The goal is to ensure even and uniform coverage, allowing the VpCI® vapors to circulate and reach all metal surfaces within the enclosure.
• Can I use Cortec VpCI-337 to protect the edges of coils or stacks of metal sheets?
Yes, Cortec VpCI-337 is highly effective for protecting the edges of coils and stacks of sheet stock. It can be sprayed directly onto these areas, and the vapor phase action ensures that the protective molecules migrate into the internal layers, preventing speckling and staining that can occur with humidity and condensed moisture.
• Do I need to clean or prepare metal surfaces before applying VpCI-337?
One of the significant benefits of Cortec VpCI-337 is that in most cases, no degreasing or stripping is necessary before application. The product is designed to be ready-to-use, allowing for a clean, rust-free surface on the metal without extensive pre-treatment.
• What if I need to paint or further process the metal after using VpCI-337? Will the film affect it?
Generally, the thin protective film left by VpCI-337 will not affect subsequent processes like painting. It also typically doesn't impact the appearance or electrical conductivity of the metals or alloys, which is a big plus for manufacturing and industrial applications.
• Is there a special version of Cortec VpCI-337 for extremely cold temperatures?
Yes, Cortec offers a "winterized" formula of VpCI-337. While the regular fluid has a very low freezing point, the winterized version is specifically designed with an even lower freezing point, making it suitable for convenient application and storage in very cold environments without performance compromise.
Relevant products you may want to consider:
• How long does the protection from Cortec VpCI-337 typically last indoors?
When applied correctly for indoor protection, Cortec VpCI-337 can provide effective corrosion inhibition for up to 12 months. This makes it an excellent solution for long-term storage of equipment or in-process protection.
• Can I use this product on packaging materials like cardboard or wood?
Yes, Cortec VpCI-337 is safe for use on various packaging materials, including cardboard, wood pallets, and foam packaging materials. This allows for comprehensive protection of metal parts stored or shipped within these enclosures.
Benefits & Features: Why Choose VpCI-337?
• What makes VpCI-337 a "multi-modal" corrosion inhibitor?
Cortec VpCI-337 is considered multi-modal because it offers both contact and vapor phase corrosion inhibition. This means it protects metal surfaces it directly touches, as well as those it reaches through the vapor released into an enclosed space, ensuring comprehensive protection.
• How does the "self-healing film" feature of VpCI-337 benefit me?
The self-healing film is a fantastic benefit because it means the protective layer can essentially repair itself if it's scratched or disrupted. This ensures continuous corrosion protection, reducing the risk of rust development even if the film experiences minor damage.
• Does VpCI-337 really save time and money in the long run?
Absolutely. By simplifying the corrosion protection process and eliminating the need for messy applications, extensive cleanup (like degreasing or stripping), and the disposal of hazardous waste often associated with traditional rust preventatives, VpCI-337 significantly reduces labor time and overall costs. It also prevents costly damage from rust, reducing reworks and scrap.
Relevant products you may want to consider:
• Is VpCI-337 approved for use in specific industries, like food processing?
Some versions of Cortec VpCI-337 contain FDA and USDA approved ingredients, making them suitable for use on tinplate, aluminum, and other metal products commonly found in food processing or packaging industries. Always check the specific product data sheet for relevant certifications.
• Can VpCI-337 protect intricate equipment internals or hard-to-reach areas?
Yes, this is one of its strongest selling points! The vapor phase action of VpCI-337 is specifically designed to reach and protect intricate equipment internals, complex cavities, and otherwise hard-to-reach areas like pipes, boilers, and valves, where applying a traditional coating would be difficult or impossible.
