Corrosion Protection for boilers, pressure vessels, heat exchangers and other process plant equipment is a difficult task as dry removable protection is required without impacting the heat or thermal transfer properties of the equipment and yet need to protect hollow spaces from the wrath of corrosion.

Also the VCI Powders should be easily removable when this equipment is brought in operation without any mechanical cleaning.

Preserving these hollow components is achieved by spraying or fogging with VCI powder using air spray or compressed air or by pouring and rolling the powder. This can also be used for hydrotesting and aqueous coating by dissolving at 2-5% in water.

The vapor corrosion inhibitor powder evaporates slowly and drifts into hard to reach areas within the component.  As much as possible, it is important to form a sealed, airtight entity.

The VCI Crystalline Powder conforms to MIL-I-22110 specifications. The Powder is free from Silica. It is also available in Special Fogging Bucket, which is convenient to use by just attaching a blower or compressed air pipe. This makes handling the powder much easier where it does not come in contact with the user and is not breathed in during handling.

The product is nitrite free and protects multi metals like copper, aluminum, zinc, lead, tin etc.
