ZERUST® Zeriol™ MCV-F-200
ZERUST® Zeriol™ MCV-F-200 is an oil-based corrosion preventive that combines contact inhibition with vapor-phase corrosion inhibitor (VCI) technology for internal protection of metal components in sealed environments. It may be applied as a thin oil film or used as a lubricant oil additive for preservation during storage, shipment, or layup. When properly applied in sealed systems, including oil-filled preservation, MCV-F-200 provides multi-year corrosion protection*; unsealed systems are not recommended.
Typical Applications*
Direct Application (Spray / Fog / Mist)
• Closed piping, vessels, compressors, rotating equipment, and sealed skid packages
• Valves, spares, machined components, pump sets, and gearboxes
• Post-hydrotest or dry layup preservation prior to commissioning
Lubricant Oil Additive (Preservation Use)
• Engines, compressors, gearboxes, and hydraulic systems during storage or shipment
• Oil-lubricated systems requiring protection of wetted surfaces and vapor space
Key Advantages
- Combined contact oil film and VCI vapor protection
- Vapor-phase action protects enclosed voids and crevices
- Suitable for fogging large enclosed volumes
- Compatible with many lubricating and hydraulic oils (verify prior to use)
- High flash point; barium- and heavy-metal-free
- Removable by oil change or conventional alkaline or solvent cleaning
- Performance validated by internal laboratory testing (ASTM D1748, ASTM B117)**
Operating Summary
Spray /Fog Application
• Clean and dry internal surfaces; remove all free water.
• Apply by spray, mist, or fog at 200 mL per m³ internal free volume (baseline).
• Use low-pressure air or nitrogen to distribute product.
• Seal all openings to retain VCI vapor (nitrogen blanket optional).
• Record dosage, treated volume, and preservation date.
Lubricant Oil Additive Application
Zeriol MCV-F-200 may be blended into compatible lubricating or hydraulic oils to provide combined contact and vapor-phase corrosion protection during storage or layup.
• Typical addition rate: 3% v/v (consult ZERUST® for alternate rates)
• Blend into new or clean oil prior to filling
• Do not add concentrate directly to operating equipment
• Fill and circulate or rotate components to ensure distribution
• Seal system to allow vapor saturation
* Please contact a ZERUST® representative for specific dosage, application equipment guidance and recommendations.
