Zerust Axxanol 707C VCI Oil Additive

What Is Zerust Axxanol 707C?

Zerust Axxanol 707C is a high-performance vapor-phase corrosion inhibitor (VCI) concentrate developed by ZERUST/EXCOR for use as an additive in lubricating oils. Unlike surface-applied coatings, Axxanol 707C works by releasing corrosion-inhibiting molecules in vapor form into the enclosed air spaces of sealed lubricated systems. These vapors condense on exposed metal surfaces — including areas that oil film alone cannot reach — forming an invisible, self-replenishing molecular barrier that actively prevents rust and corrosion.

The product is a concentrate designed to be blended directly into the host lubricating oil at the recommended treat rate, making it straightforward to integrate into existing maintenance and lubrication programs without requiring equipment modifications.

How VCI Technology Works

Vapor Corrosion Inhibitor technology relies on the controlled volatilization of corrosion-inhibiting compounds. When Axxanol 707C is blended into a lubricating oil, its active VCI molecules partition between the liquid phase and the vapor phase within the closed system. The vapor-phase molecules migrate through void spaces and adsorb onto all accessible metal surfaces — including those above the oil line — creating a continuous, self-healing protective layer.

This dual-phase protection is particularly valuable in systems where oil splash or mist does not consistently coat all internal surfaces, such as the upper cylinder walls of engines during storage, or the headspace of gearboxes and hydraulic reservoirs.

Key Applications and Industries

Axxanol 707C is suited to a broad range of closed lubricated systems across heavy industry. Primary applications include:

• Internal combustion engines (diesel and gas) — particularly during storage, standby, or infrequent operation
• Transmissions and gearboxes in heavy equipment, trucks, and industrial machinery
• Hydraulic systems in construction, oil field, and manufacturing equipment
• Marine propulsion and auxiliary systems exposed to salt-air environments
• Oil and gas production and processing equipment, including pumps, compressors, and rotating machinery
• Power generation equipment and standby generators

Dosage and Application Guidance

Axxanol 707C is added directly to the lubricating oil in the system at the manufacturer's recommended treat rate. The concentrate blends readily with most mineral and synthetic lubricating oils without requiring special mixing equipment. For specific dosage rates and compatibility with your base fluid, consult the product technical data sheet or contact your ZERUST/EXCOR representative. As with all oil additives, it is advisable to verify compatibility with the existing oil formulation and any other additives in use.

Performance in Gulf and Middle East Conditions

Industrial assets in the Gulf region face some of the most aggressive corrosion conditions in the world. High ambient temperatures accelerate electrochemical corrosion reactions, while coastal humidity and airborne salt particles create a highly corrosive environment for ferrous and non-ferrous metals alike. Equipment that sits idle during seasonal shutdowns or between project phases is especially vulnerable.

Axxanol 707C addresses these challenges directly. Its vapor-phase mechanism ensures that corrosion protection reaches every internal surface of a sealed system — not just those wetted by oil — providing continuous protection even during extended idle periods. This makes it a practical and cost-effective solution for asset preservation in oil and gas, petrochemical, marine, and heavy manufacturing operations across Saudi Arabia, the UAE, Kuwait, Qatar, Oman, and Bahrain.
