PRODUCT DESCRIPTION 

Ecofog® VpCI®-337 is a ready-to-use waterborne vapor corrosion inhibitor for temporary protection of equipment and plants. It is a complete replacement for nitrogen blanketing and dry air systems that are both expensive to install and maintain. Nitrogen blankets are also a health hazard to personnel entering the interiors. Vapor phase Corrosion Inhibitors (VpCIs) in Ecofog® VpCI®-337 migrate and protect metal surfaces, resulting in time and cost savings. The Ecofog® VpCI-337 is used to fog void spaces, tanks, containers, packages, and enclosures. These labor-saving techniques use a minimum of product to protect large areas or volumes. Ecofog® VpCI®-337 is effective on ferrous and non-ferrous metals as well as aluminum, plated steels, and copper. Ecofog® VpCI®-337 is consistently successful in providing protection to the basic metals, metalworking, and packaging industries. 

In most cases, products protected by Ecofog® VpCI-337 are ready-to-use. No degreasing or stripping is necessary by most end users. The metal will retain a clean, rust-free surface. In most cases, the thin protective film will not affect paintability, conductivity, appearance, or any other important property of metals or alloys.

Ecofog® VpCI®-337 is also available in a cold weather version. 

Ecofog® VpCI-337 Winterized has a lower freezing point for the convenience of application and storage in cold temperatures..
