Cortec VpCI® 391 Water Based Temporary Coating | 19ltr / 5 Gallon Drum Pail

Cortec VpCI-391 is a groundbreaking water-based temporary coating that offers exceptional corrosion protection in challenging outdoor, unsheltered environments. It's considered revolutionary because it provides multi-metal protection, excellent UV resistance, and dries to a clear, non-tacky film, all while being easily removable when its job is done.

Cortec VpCI-391 utilizes advanced Vapor phase Corrosion Inhibitor (VpCI) technology. This means that after application, the VpCI molecules vaporize and form a protective, monomolecular layer on all exposed metal surfaces, both direct and recessed, safeguarding them from rust and other forms of corrosion.

Yes, absolutely! Cortec VpCI-391 is designed with environmental responsibility in mind. It's a water-based formulation with low VOC (Volatile Organic Compound) content, making it a safer and more sustainable choice compared to many traditional solvent-based coatings.

Upon drying, Cortec VpCI-391 leaves behind a clear, hazy, and non-tacky film. This inconspicuous finish is one of its key advantages, as it protects without significantly altering the appearance of the coated item.

Cortec VpCI-391 is formulated for medium to long-term outdoor protection, offering significant corrosion resistance for up to five years, even in unsheltered conditions, which is quite impressive for a temporary coating.

For the best performance, ensure the surface is clean and free from loose rust, oil, grease, and other contaminants. Cleaning with an appropriate degreaser, such as a Cortec VpCI-415, can help achieve a well-prepared surface.

One of the great features of Cortec VpCI-391 is its versatility; it can be directly applied over both bare metal surfaces and previously painted surfaces, providing excellent protection without negatively affecting the existing finish.

Cortec VpCI-391 is very flexible in its application. You can easily apply it by spraying, rolling, brushing, or even dipping, depending on the size and shape of the item you need to protect.

Cortec VpCI-391 is designed to be fast-drying, typically becoming dry to the touch within 30 to 60 minutes at 75°F (24°C), which is beneficial for quick turnaround times in various operations.

For robust protection, a dry film thickness of 1.0 to 3.0 mils (25-75 microns) is generally recommended. This thin layer is enough to provide significant corrosion inhibition without adding bulk.
