Cortec® Corporation has introduced BioPouch™, the latest advancement in environmentally safe corrosion protection. This revolutionary, “green” vapor-phase corrosion inhibitor (VpCI®)is aimed for protection of metal parts in a non-ventilating space. BioPouch is powered by 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, is free of nitrites, halogens and phosphates, and is completely safe to handle.

It 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.

BioPouchis quick and 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 1 m3 of enclosed space.

Typical uses include:

  • Tubular structures, pipes, and vessels;
  • Internal surfaces of compressors, turbines, engines, tanks, boilers, heat exchangers;
  • Steam condensate lines, closed circuit heating and cooling systems;
  • Corrosion protection of equipment after hydrostatic testing;
  • Parts, components and completed assemblies during shipping and storage;
  • Voids, cavities and tanks;
  • Double bottom storage tank floors.

BioPouch is tested according to NACE TM0208-2008 and conforms to RoHS guidelines.
