ZERUST® ActivDri™ PWA Packets

ZERUST® ActivDri™ PWA Packets are a dual-action corrosion protection solution that combines proven Vapor Corrosion Inhibitor (VCI) chemistry with an active desiccant to control moisture. The VCI molecules volatilize within enclosed packaging and form an invisible, self-replenishing protective layer on metal surfaces, halting the electrochemical reactions that cause rust and corrosion. Simultaneously, the desiccant component actively absorbs excess moisture from the surrounding environment, reducing relative humidity to levels that prevent condensation and corrosion-accelerating dampness.

These packets are designed to protect a wide range of materials including ferrous and non-ferrous metals, sensitive electronics, printed circuit boards, and electrical components and equipment. Their compact, flexible packet format allows easy placement inside boxes, bags, crates, and equipment enclosures without requiring direct contact with the protected surface. This makes them an ideal choice for industrial packaging, long-term storage, and international shipping — particularly for high-value components and assemblies that cannot afford corrosion-related failures.

For buyers across the Gulf and Middle East, where extreme summer heat, persistently high humidity, and corrosive salt air create some of the world’s most aggressive corrosion conditions, ZERUST® ActivDri™ PWA Packets offer a cost-effective and reliable line of defence. Their economical price point and ease of use make them suitable for large-scale industrial operations, warehousing, and export packaging, delivering long-lasting protection without the need for complex application equipment or specialist training.
