Next generation of corrosion inhibiting fuel additives
Cortec has developed the next generation of VpCI fuel additives for more potent corrosion protection of fuel systems. Cortec VpCI-707 has been specially formulated to protect fuel tanks and systems from corrosion and sludge formation without damaging copper and aluminium. It is a powerful option for keeping new and existing fuel tanks and systems in good condition during day-to-day operation and especially during vulnerable times such as intermittent operation, storage or shipment. Other benefits of VpCI-707 are its improved water handling and good injector-cleaning capabilities. VpCI-707 does not contain trace metals, chlorides, chromates, nitrites, phosphates or secondary amines.
Because of its combined contact-phase and vapour-phase action, VpCI-707 effectively provides corrosion protection to metal surfaces not only in direct contact with the treated fuel, but also in the void space above the fuel line. This allows VpCI-707 to be applied at a very low dose compared to the volume of the tank being protected. VpCI-707 can be added directly to gasoline or diesel fuel in blending, storage or vehicle tanks. It can also be fogged as a concentrate into dry fuel tanks before storage and shipment.
Comparing Cortec fuel additive protection
With the development of VpCI-707, Cortec R&D has made an excellent improvement to its fuel additive offerings. VpCI-707 outperforms VpCI-705 in many aspects, including fuel stability and contact- and vapour-phase corrosion protection. While VpCI-705 remains an excellent preservation tool with a long-standing history, VpCI-707 represents the newest generation of corrosion protection in fuel systems. Compared to VpCI-706, which provides the strongest vapour-phase protection of all three additives but is corrosive to copper, Cortec’s new VpCI-707 is a powerful alternative for use when multi-metal protection is needed, or when protection is needed for fuel components that may not be fully enclosed.
The importance of fuel additives
Applying a good corrosion inhibiting additive to fuel tanks and systems is an important part of the preservation process especially when vehicles, tanks, or equipment will be going through a period of disuse. Otherwise, harsh environments and stagnation can lead to sludge formation and the deterioration of even new metal components. VpCI-707 can be used for fuel stabilisation and corrosion protection in countless applications, such as in the following:
- large or small fuel storage tanks
- heavy equipment or vehicles being shipped overseas
- equipment operating in harsh industrial or offshore environments
- generators or other equipment going into seasonal storage, and
- industrial plants going into temporary layup.
