Cortec® Corp., a global provider of green, sustainable technologies, introduces the latest advancement in environmentally safe corrosion protection—BioPouchTM. This Vapor phase corrosion inhibitor 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.

The company says BioPouch is designed to protect and preserve a variety of metal components from oxidation, and this may include medical devices. The simplest and most common way to use the product would be to place a pouch inside a box or other shipping container with metal components. A Cortec professional notes this formulation does not have any FDA/USDA approvals. If it were to be used on a medical device or similar equipment, those surfaces would have to be properly cleaned prior to use.

Molecules from BioPouch are attracted to and adsorb onto metallic surfaces, resulting in the formation of a nano protective barrier layer. Studies have shown the 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 provides an 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® does not destroy the natural balance of the environment. The company says it is functionally superior to hazardous oil derived products. It is effective in polluted and humid surroundings. BioPouch requires no 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.

Typical uses for BioPouch include the following:

• 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.
