Vapour phase corrosion inhibitors (VpCIs) are not widely known, but provide excellent results in mothballing vital plant and equipment.

Savcor Products has been importing VpCIs for many years from the Cortec Corporation, a US-based technology company.

The corrosion inhibitor emits an environmentally friendly vapour that condenses on the metal surface of the mothballed asset to form a thin, uniform, economical and extremely effective corrosion inhibiting layer.

VpCIs come in many different forms, such as plastic films and wraps, coatings, powders and emitters, and Savcor says that the use for this technology is unlimited.

Some of the ways in which Savcor has helped clients in mothballing include:

  • VpCI impregnated coatings, powders and liquids for protecting all surfaces, including engine and gearbox internals of vintage vehicles as displayed and stored in museums;
  • Milcorr – a heavy-duty VpCI shrink-wrapping film for protecting vital equipment from corrosion and weathering;
  • Concentrated oil and fuel additives for heavy mining equipment, such as gearboxes;
  • Powders added to many enclosed spaces, such as dredge chambers, piles and lighting poles for long-term protection; and,
  • Emitters used to protect electrical switchboard cabinets.

VpCIs are a cost effective way of providing corrosion protection and reducing long-term maintenance costs.
