What is the function of Corrosion Inhibitor?

The use of corrosion inhibitors has widespread application in suppressing or at least mitigating the corrosion process of metals in different fields, from industrial sectors to construction materials to surface treatments for cultural heritage. Metal corrodes when it reacts with other substances such as oxygen, hydrogen, an electrical current, or even dirt and bacteria from the surrounding as long as it has been exposed to the substances mentioned earlier. Metals such as steel can also corrode when so much stress or pressure has been exacted on them, causing the material to crack. With this, the most frequent question been asked is the need how to protect/ prevent our metals from corroding. Hence inhibitors have always been the first line of defense against corrosion.

What is a Corrosion Inhibitor?

A corrosion inhibitor is a chemical substance that, when present in the corrosion system at a suitable concentration, decreases the corrosion rate by significantly changing the concentration of any corrosive agent. It is generally effective in small concentrations.

A corrosion inhibitor is a chemical that could be in either a liquid state or gaseous state that can be added to reduce or slow down the corrosion rate of the metal. Corrosion is usually due to Oxygen, water, dirt, and bacteria.

Types of Corrosion inhibitor

Epochem Corrosion inhibitors are classified into two general types due to the nature in which they prevent corrosion. Some corrosion inhibitors also serve as an industrial coolant and protect engines’ cooling system, while others reduce the corrosion rate of metals. They include;

1. Water-based inhibitor

The water-based inhibitor is an Epochem brand of Cleaning and maintenance chemicals in Nigeria. This corrosion inhibitors coolant is a series of extended-life industrial coolant/antifreeze and heat transfer fluids formulated for stationary equipment applications already pre-diluted. These products are based on a unique extended-life carboxylate inhibitor system and nitrite/molybdate as secondary inhibitors. These water-based inhibitors provide complete protection of cooling system components, do not contain borates, phosphate, amines, and silicates, and are available in ethylene glycol-based fluid.

Procedures For Use

• Allow the cooling system to cool thoroughly. Drain traditional coolant from the cooling system.

• Dispose of all coolant according to all laws and regulations.

• Fill cooling system with clean water and circulate system until normal operating temperatures are reached.

• Circulate system for 15 to 30 minutes after reaching normal operating temperatures.

• Check the system for any leaks and replace any worn materials.

• Drain the water from the cooling system completely

• Dispose of all re-circulated water according to all laws and regulations. Water that remains in the cooling system will affect the freezing point of the new coolant when added.

• Re-filling the cooling system, If using Epocool 2000 Corrosion Inhibitors coolant. Fill the cooling system about 9/10 full with Epocool Pre-diluted 50/50. Circulate system until normal operating temperature is reached. Test freeze point and adjust to between -15ºF and -62ºF. The optimal freeze point is -34ºF.

• For over-concentrated systems, use water to make freeze point more positive. The circulated system after the freezing point has been adjusted.


• Check the coolant level regularly. If systems are prone to leaking, more frequent checking of the cooling system is recommended to maintain proper fluid levels. Top up as required with Epocool 2000 Corrosion Inhibitors Coolant.

• Coolant levels should be maintained to ensure correct cooling system operation and avoid headspace corrosion.

• For ethylene glycol systems, check the freezing point at least twice per year using a refractometer and adjust to between -15ºF and -62ºF. The optimum freeze point is -34ºF.

  1. Solvent-based inhibitor

The solvent-based Epochem brand of Cleaning and maintenance chemicals in Nigeria. It is applied to an environment that significantly reduces the corrosion rate of materials, especially metals exposed to that environment. It is considered the first line of defense against corrosion.

These solvent-based corrosion inhibitors are corrosion preventatives for application to surfaces likely to corrode, either in storage or in use. They are blends of selected rust prevention materials dissolved in a solvent for ease of application. On application, the solvent evaporates, leaving a protective coating.

Why you should use Corrosion inhibitor

Corrosion Inhibitors have a wide range of applications in various sectors, and it is important to eliminate rust or corrosion from business facilities, homes, and industrial environments. Some of these uses are listed below.

Corrosion Inhibitors are used to slow down or stop rusting and anodic corrosion of metals. This is usually done via the coating of the metal surface with a chromate layer. Oxygen scavengers can be used as Corrosion Inhibitors to react with dissolved oxygen in the environment and can help in preventing cathodic corrosion.
