Cortec®’s VpCI® 389 Number One Choice for
& Outdoor Multimetal Corrosion Protection!
VpCI®-389 is an environmentally friendly water-based, temporary coating that delivers
exceptional multimetal protection for outside applications and salt-spray resistance. This
contemporary coating is an advanced, safe replacement for hazardous oil-based products. It is an
excellent choice for long-term indoor protection that lasts up to 5 years and short to medium-term
(6-24 months*) unsheltered outdoor protection.
VpCI®-389 temporary coating is the best solution on the market for applications such as equipment lay-up, parts
processing protection, overseas shipping, maintenance repairs and parts storage.
This completely safe and easy to use coating cures to a soft film and eventually hardens. It is very
efficient in SO2 and H2S environments. The product leaves a translucent, waxy coating that is
easily removable, it is low in VOC’s and dilutable with water. VpCI®-389 can be easily removed
with alkaline cleaners, such as Cortec VpCI-414. It is available in ready-to-use form - VpCI-389
D (1:1). Metals protected are: aluminum, steels, cast iron, copper alloys and tin plated steel.
Traditional coatings rely on sacrificial metals (zinc, chromates, aluminum) for inhibition. Due to
the large particle size of these inhibitors, gaps exist which allow corrosion to start and eventually
expand, causing coating failure. Cortec® VpCI-389 coating uses the patented VpCI® technology
to protect the metal substrate with a tight bonding molecular structure. This system eliminates the
gaps which occur with traditional inhibitors and prevents corrosion from starting. With
environmentally safe VpCI® technology, the equipment and products will get superior corrosion
ExxonMobil-Qatar-Edison Snamprogetti Srl needed to prevent the progression of corrosion to the interior
of 1300 pipes stored for several months in an outdoor harsh environment. The pipes were used to transport
liquefied natural gas (LNG) from a terminal station located in the Adriatic sea. They were exposed to high
humidity, salt air and gusty winds. Once protected the pipes would remain under the same unsheltered
conditions for an additional 12-18 months. VpCI® 389 was applied to the cut-back of pipes and the pipes
were covered with Cortec's VpCI® 126 film. The corrosion problem was successfully solved and the
customer was very satisfied with Cortec's solution. Later inspection showed no further corrosion in the
