VCI FABRIC

WHAT IS CORROSION?

Corrosion is a constant, indiscriminate and costly enemy of metal parts, especially when packaged for storage and distribution. Traditional anti-corrosion methods are messy, costly and can be hazardous to personnel and the environment. Too often, they are ineffective as well.

Globally the losses every year due to corrosion are estimated to be unimaginable US$ 828 billion per annum. i.e. US$ 2.27 Billion per day. (NACE)

WHAT IS A VCI (Volatile Corrosion Inhibitor)?

VCI is a mixture of special chemicals that constantly vaporize and create gases, which have anti – corrosion properties. These vapors form a very thin protective film layer around the metal surface and prevent the metal from the corrosion action.

VCI chemicals dissociate into anions and cations with moisture as an electrolyte. These anions and cations associate with anodic and cathodic reactive areas respectively on the metal surface forming a mono-ionic protective layer, making it inert for any further reaction such as oxidation/rusting. Any loss of ions is replenished through further condensation of vapor ensuring continuous protection.

VCI Paper, or Vapour Corrosion Inhibitor paper, is a Kraft packaging paper manufactured with added VCI chemistry. VCI molecules protect metals from corrosion by forming a thin, invisible layer on the surface. This layer inhibits the corrosion process caused by oxygen, water and contaminants.

VCI Packaging can be offered in various configurations depending upon applications

VCI Fabric is a high strength Fabric wrapper infused with hi-tech VCIs, making it flexible and easy to wrap around objects to protect them from rust and corrosion.

KEY FEATURES

o High strength HDPE fabric laminate for heavy duty application
o Especially suitable for wrapping on automatic machines
o Protection for ferrous, non-ferrous and composite metals
o Available up to 3000 mm width (seamless) and with 2 color custom printing
o Also available as 2 dimensional & 3 dimensional bags/covers

CONSTRUCTION

VCI Fabrics are constructed with waterproof woven PE fabric on one side and extrusion coated with PE based multi-metal VCI formulations on the other. The product imparts strength and corrosion protection to metal surfaces.

APPLICATION

o Protection of metal coils, sheets, tubes, and wires where extra strength and high tear resistance is required
o CR coils galvanized coils (white rust protection) and non-ferrous coils (protection from tarnishing/oxidation)
