Worldwide technical service

Our field scientists and engineers work closely with customers to design and implement comprehensive corrosion management systems. Then, Zerust/Excor representatives worldwide provide on-site technical support to ensure the effectiveness of these solutions.

For any cases of corrosion, we provide our support through our Research and Application laboratories. Our technical team provide multiple training and on-site installation for our customers.

What is Zerust® VCI technology

ZERUST® EXCOR® technologies are a set of non-toxic and recyclable volatile corrosion inhibitor (VCI) protection solutions.

Principle of operation

Through sublimation, the VCI (Volatile Corrosion Inhibitors) vapors saturate the atmosphere inside the packaging and condense on all accessible surfaces of the metal part, forming a protective ionic film.

How Zerust® Vapor Corrosion Inhibitor Technology Works

What is VCI?

VCI is an abbreviation for Vapor Corrosion Inhibitor or Volatile Corrosion Inhibitor. VCIs are molecules that inhibit corrosion by forming a thin protective layer on a metal surface within an enclosed space. This invisible layer prevents moisture and environmental elements from reacting with the metal surface and causing corrosion. The molecules dissipate when the enclosure is open and should not be removed.

Corrosion definition

Atmospheric corrosion is a natural process of weathering a metal. Corrosion of metal generally starts when moisture condenses on its surface. The moisture, present on the surface of the metal, forms an electrolyte that allows electrons to circulate. This process results in visible oxidation (rusting or tarnishing).

Protecting metals with VCI

Moisture and contaminants in the atmosphere react with the metal surfaces and cause corrosion.

VCIs can be used to protect these metal parts from corrosion without the need for greases or painting. Zerust VCIs have been effectively and safely used to protect valuable parts and equipment for more than 35 years.

How ZERION FVS Technology Works


Corrosion of aboveground storage tanks, equipment while out of use during long periods of time, exposed steel surfaces, voids, enclosures and more.

Zerust Zerion® FVS is a versatile new corrosion inhibitor specifically designed to protect ferrous metals in aggressive corrosion environments where there is the possibility of the accumulation of water, moisture and/or water ingress. Zerion FVS provides unique dual action corrosion protection. This new dimension of effectiveness makes Zerion FVS the best in class in the market today.

Morgreen is an Engineering Consultancy, Corrosion, and Inspection company established since 1993.

LP Compressor Rotor restoration and preservation for Total E&P Nigeria.

The material was received rusted as shown in the picture. It was thoroughly cleaned, restored, and preserved for storage and future use with corrosion free. We use a custom Zerust® VCI packaging to protect compressors. VCI packaging protects the metal parts from rust. It allows the integrity of the parts for several years.

Corrosion solutions FAQ

Do you have questions about VCI corrosion solution?

How do VCI materials prevent materials from corroding ?

Sublimation (evaporation) of the VCI molecules from the carrier material Diffusion (distribution) of VCI molecules in the packaging space Adsorption of a closed VCI film at the metal’s surface

Does VCI materials protection expire? If yes, how is it monitored?

The VCI materials have different protection timeline and it been monitored by the preservation application.

Is the product toxic / poisonous.

Our VCI anti-corrosion products are Non-toxic, non-abrasive, non-allergenic, and biodegradable.

What is the benefit of inventory preservation in an organization.

Presently the rate of materials write-off as a result of corrosion, damage, or deterioration has reduced by more than 60% in NLNG warehouse.

Does VCI materials leaves residual on the material surface?

VCI technology does not leave residue on contact surfaces.

How do you preserve non-metallic materials.

In preservation methodology, we cover safe materials handling, best storage conditions, and shelf life monitoring and manufacturer's advice.
