VpCI vapor phase corrosion inhibitors provide multi-metal corrosion protection for metals like steel, stainless steel, cast iron, zinc and aluminum. VpCI forms a thin, self-healing protective film that is environmentally friendly and protects immediately upon application. It can protect metals during storage, transportation or operation. VpCI protects in hard to reach areas like crevices through its vapor which condenses and forms a protective layer on all surfaces. It is more efficient and safer than traditional oil coatings as it does not require cleanup and is not based on nitrites. VpCI can cut costs over the life of a product by preventing corrosion during manufacturing, storage, shipping and use without additional processing steps.
