VpCI Corrosion Inhibitor metal components are usually packed in cartons, paperboard boxes, or corrugated materials to prevent physical damage during handling and transport. While these packaging options protect against scratches and impact, they do not stop corrosion.

Moisture can enter packaging at different stages—during storage, loading, or transit. Temperature shifts between indoor and outdoor environments can also cause condensation inside the package. This is common when goods move between air-conditioned spaces and hot outdoor conditions.

VpCI-350 AHS is designed to address this issue. It is a liquid VpCI Corrosion Inhibitor applied to paper and board surfaces. Once dried, the treated packaging helps reduce the risk of rust on metal parts stored inside.

The coating does not leave the paper greasy or sticky. Instead, it forms a light layer that releases corrosion-inhibiting vapours within the enclosed space. These vapours spread throughout the package and reach exposed metal surfaces, including areas that are difficult to cover directly.

Nassguard supplies VpCI-350 AHS across Qatar and Doha for packaging companies, manufacturers, exporters, and industrial users.

What is VpCI-350 AHS?

VpCI-350 AHS is a water-based coating developed for corrosion protection in paper and corrugated packaging materials such as kraft paper, linerboard, and chipboard.

Manufacturers apply the liquid during the paper conversion process. After drying, the treated material can be cut, folded, printed, or glued into different packaging formats like wraps, cartons, liners, or inserts.

When metal parts are packed inside, the Vapor Phase Corrosion Inhibitors activate within the enclosed space. The vapours move through the air inside the package and form a thin protective layer on the metal surface.

This process helps protect areas that are not in direct contact with the paper, such as corners, threads, cavities, and small openings.

The coating also keeps components clean. It does not leave heavy residues like oil or grease, so parts can often be used directly without additional cleaning.

Uses of VpCI Corrosion Inhibitor

VpCI-350 AHS is used by packaging manufacturers to produce protective materials for various industrial applications.

• Treating kraft paper for wrapping metal parts
• Coating linerboard before box production
• Producing folding cartons for industrial goods
• Making separators for stacked components
• Preparing interleaving sheets for metal plates
• Creating inserts for machinery packaging
