VpCI® Technology for Marine and Shipbuilding Industries
Defending vessels, offshore assets, and marine infrastructure against the most aggressive corrosion environment on earth.
The Corrosion Challenge
Saltwater, humidity, and marine atmospheres create a relentless corrosion environment.
Marine environments are uniquely destructive. Salt-laden air accelerates corrosion on exposed surfaces. Condensation forms inside enclosed spaces as temperatures fluctuate between day and night. Bilge water, ballast tanks, and void spaces trap moisture in areas that are almost impossible to inspect or maintain regularly.
During layup periods — whether planned maintenance, seasonal downtime, or decommissioning — the corrosion risk intensifies. Engines, generators, hydraulics, and electrical systems sit idle without the heat and circulation that normally help keep moisture at bay. Without active protection, pitting corrosion can render precision components unserviceable within months.
Cortec VpCI® technology provides comprehensive protection across all these scenarios. VpCI molecules reach into crevices, threaded connections, and internal surfaces that conventional coatings and oils cannot access. The protection is self-replenishing — as long as the VCI source remains in place, the molecular barrier continuously renews itself on the metal surface.
Our Solutions
Cortec VpCI® products for above-waterline and below-waterline marine protection.
VpCI® Coatings
High-performance, VpCI-enhanced coatings for above-waterline surfaces, deck machinery, and superstructure protection. These coatings combine barrier protection with vapour-phase corrosion inhibition, reaching into crevices and hard-to-coat areas that conventional coatings miss.
