Frequently Asked Questions
• What exactly is Cortec CorShield VpCI-368, and what's its primary purpose?
Cortec CorShield VpCI-368 is a high-performance, solvent-based temporary coating designed to provide exceptional multi-metal corrosion protection, especially in challenging outdoor environments where assets are exposed to the elements. It’s essentially a robust shield that guards your valuable metal assets. For more information, you can explore Cortec CorShield VpCI-368 and other VpCI Corrosion Inhibitor Coatings.
• How does this coating work to prevent corrosion?
This innovative coating forms a firm, wax-like film on the metal surface. What makes it special is its Vapor phase Corrosion Inhibitor (VpCI) technology, which creates a protective molecular layer that actively prevents rust and corrosion from forming, even in the presence of moisture and harsh elements. Discover more about VpCI Vapor Phase Corrosion Inhibitors.
• Is VpCI-368 a permanent coating, or can it be removed?
No, VpCI-368 is designed as a temporary protective coating. While it offers long-term, multi-year outdoor protection, it can be easily removed when it's no longer needed, typically using alkaline cleaners like Cortec VpCI-414. Other options include Cortec VpCI-414 Cleaner Degreaser Aerosol Cans and Cortec VpCI-422 Biodegradable Rust Remover.
• What types of metals can CorShield VpCI-368 protect?
This versatile coating provides excellent multi-metal protection, making it suitable for both ferrous metals (like steel and cast iron) and non-ferrous metals (such as copper and aluminum), ensuring a broad range of applications. Consider other protective products like Cortec CorShield VpCI-369 for similar protection needs.
• How does VpCI-368 stand up to harsh weather conditions?
Cortec CorShield VpCI-368 is specifically engineered for unsheltered, exposed environmental conditions. It boasts excellent salt-spray and UV resistance, meaning it can withstand tough outdoor elements, from intense sunlight to salty air, effectively protecting the underlying metal. This is also why products like Cortec VpCI-126 HP UV Blue Shrink Film are essential for outdoor storage.
Practical Applications and Usage Scenarios
• Where would someone typically use Cortec CorShield VpCI-368 for corrosion prevention?
This coating is incredibly versatile and is commonly used for protecting assets during various stages of their lifecycle, including long-term outdoor storage, transit, and equipment layup. Think of anything from heavy machinery left outdoors to components being shipped across oceans. Also consider Nox-Rust Transit Coatings for transport needs.
• Can you give specific examples of metal components that would benefit from this coating?
Absolutely! It’s ideal for pipe coatings, protecting parts in storage, underbody coating for vehicles or equipment, wire ropes, steel plates, machined parts, and even for the long-term protection of permanent outdoor metal structural components.
• Is it suitable for equipment that might be stored outside for extended periods, even years?
Yes, that's one of its key strengths. Cortec CorShield VpCI-368 is designed to provide multi-year outdoor protection in harsh conditions, making it an excellent choice for assets that will be exposed to the elements without additional shelter.
• Could I use this product to protect machinery that is being transported overseas?
Definitely! It's an excellent solution for protecting equipment during transit, especially when combined with appropriate packaging. It helps ensure that your valuable machinery arrives at its destination free from corrosion, even after long journeys in varying climates. Look into VCI Bags and Films or MIL-PRF-131 barrier foils for complementary solutions.
• Does CorShield VpCI-368 offer protection for both painted and unpainted metal surfaces?
Yes, it's quite flexible. This coating can be applied effectively over both machined, plated, or other bare metal surfaces, as well as over existing coatings or finishes, expanding its utility.
Application Guidelines and Best Practices
• Do I need to do any special surface preparation before applying VpCI-368?
Proper surface preparation is crucial for optimal performance. You need to ensure the substrate is clean and free from grease, oil, dirt, fingerprints, and any other surface contamination that could hinder adhesion. For bare metals, a NACE #3/SSPC-SP6 standard is recommended for best results.
• Is it necessary to mix or agitate the product before application?
Yes, it's important to agitate and mix VpCI-368 thoroughly before use to achieve a uniform consistency. A "squirrel cage" type mixer or an equivalent handheld drill mixer is recommended for this.
• What are the common methods for applying CorShield VpCI-368?
This solvent-based coating is quite versatile in its application methods. It can be applied using a spray, brush, roller, or even by dipping, giving you flexibility depending on the size and shape of the item you're protecting. For spray applications, consider the Cortec CorShield VpCI-368 Outdoor Corrosion Protection Spray.
• If I'm using a spray gun, what kind of equipment setup is typically recommended?
For assisted airless and airless applications, a tip size of 0.015”-0.035” (0.38-0.89mm) is generally suitable, with pressure set between 1800 and 2500 psi. It's also recommended to use a ⅜” (0.95cm) internal dimension hose as a minimum.
• What is the recommended film thickness for optimal protection?
For effective protection, especially for uncovered outdoor storage, a dry film thickness (DFT) of at least 2-3 mils (50-75 microns) is recommended. This usually corresponds to a wet film thickness (WFT) of 4-6 mils.
Drying, Removal, and Maintenance
