ZERUST® Zerion™ FVS Corrosion Inhibiting Powder

Product Overview

ZERUST® Zerion™ FVS is a high-performance corrosion inhibiting powder designed for industrial environments where vapor spaces coexist with the risk of water ingress. Unlike single-mechanism inhibitors, Zerion™ FVS integrates both Vapor Corrosion Inhibitor (VCI) and Soluble Corrosion Inhibitor (SCI) chemistries into one versatile powder formulation, delivering layered protection against corrosion in even the most challenging conditions.

How It Works

Vapor Corrosion Inhibitor (VCI) Action

The VCI component volatilises within enclosed spaces, forming a protective molecular layer on metal surfaces. This invisible barrier interrupts the electrochemical reactions responsible for corrosion, providing continuous protection without requiring direct contact with the metal surface.

Soluble Corrosion Inhibitor (SCI) Action

When water ingress occurs, the SCI component dissolves into the aqueous phase and actively neutralises corrosive contaminants such as chlorides, sulfates, and acidic compounds. This dual-phase response ensures that metal assets remain protected even when condensation or water infiltration is unavoidable.

Typical Applications

Zerion™ FVS is suited to a broad range of industrial sectors and asset types, including:

• Oil & gas pipelines, vessels, and storage tanks
• Marine and offshore structures subject to salt spray and high humidity
• Industrial storage facilities and enclosed equipment housings
• Electrical enclosures and control panels in humid environments
• Preservation of idle or mothballed equipment and machinery

Usage Guidance

Zerion™ FVS powder is applied by placing or distributing the required quantity within the enclosed space or void to be protected. The powder begins releasing VCI vapors immediately upon exposure to the enclosed atmosphere. In the event of water ingress, the SCI component activates upon contact with the aqueous phase. Dosage rates should be determined based on the volume of the vapor space and the anticipated level of water ingress risk; consult ZERUST technical documentation or your regional representative for application-specific guidance.

Key Benefits

• Dual-action protection eliminates the need for two separate inhibitor products
• Powder form is easy to handle, store, and apply in confined or complex geometries
• Effective in high-humidity and water-ingress-prone environments common in Gulf and coastal regions
• Protects ferrous and non-ferrous metals without requiring direct surface contact
• Reduces maintenance costs and asset downtime associated with corrosion damage
