BioPouch Is Powered by a NANO-VpCI

ST. PAUL, MN | Cortec Corp. presents BioPouch, the latest advancement in environmentally safe corrosion protection. This new, revolutionary “green” Vapor phase Corrosion Inhibitor (VpCI) is aimed for protection of metal parts in a non-ventilating space. BioPouch is powered by newest NANO-VpCI technology, primarily made from agricultural by-products.

NANO-VpCI's emit from the pouch and saturate the enclosure via diffusion, filling all void spaces and recessed areas with protective vapor molecules. These molecules are attracted to and adsorb onto metallic surfaces, resulting in the formation of a nano protective barrier layer.

Studies have shown the excellent ability for VpCI molecules to provide protection in the presence of corrosive species, (i.e., chlorides, moisture, sulfides) and displace them at the metal surface. Vapor phase inhibiting action protects inaccessible and recessed surfaces. BioPouch is non-toxic, free of nitrites, halogens, and phosphates, as well as completely safe to handle.

BioPouch provides an extremely efficient and easy method to protect metals within an enclosed space. In case a nano-protective layer is disturbed by moisture or opening of an enclosed space, the layer is replenished by continuous vapor re-deposition.

The Nano-VpCI is made from enhanced renewable agricultural by-products and does not destroy the natural balance of the environment while being functionally superior to hazardous oil derived products. It is very effective in polluted and humid environments.

BioPouch is quick and super easy to use: there is no need for special equipment for application, just determine the number of pouches required per unit space. No spraying, wiping, or dipping is required. Each BioPouch protects up to 1m3 of enclosed space.
