ZERUST® Zerios® WUV-25 Corrosion Preventive Coating

ZERUST® Zerios® WUV-25 is a premium corrosion preventive coating designed for long-term protection of steel assets exposed to harsh outdoor conditions. Combining advanced VCI (Vapour Corrosion Inhibitor) chemistry with a robust film-forming formulation, WUV-25 delivers reliable, cost-effective corrosion control for industrial operations across the Gulf and Middle East region.

Product Overview

WUV-25 is formulated to form a durable, transparent amber film upon application. The coating is dry to the touch once cured, making it practical for handling and storage without risk of contamination or transfer. Its transparent nature means coated components can be visually inspected for condition, markings, or identification without requiring the coating to be stripped — a significant operational advantage in busy industrial facilities.

Application Areas

WUV-25 is suitable for a wide range of steel assets and industrial components, including structural steel, fabricated parts, pipework, flanges, valves, and equipment in transit or temporary storage. It is particularly well-suited to outdoor laydown yards, port facilities, construction sites, and industrial plants where assets are exposed to the elements for extended periods.

Protection Performance

WUV-25 provides up to 2 years of corrosion protection for steel assets in outdoor exposure conditions. For assets stored indoors or in sheltered environments — such as warehouses, covered yards, or climate-controlled facilities — protection can extend to several years. This extended service life reduces the frequency of reapplication, lowering total cost of ownership and minimising maintenance downtime.

Film Properties

The coating forms a transparent amber film that is visually unobtrusive and does not obscure surface markings, heat numbers, or identification stamps. Once dry, the film is non-tacky and dry to the touch, preventing dust accumulation and making coated parts easy to handle and stack. The film adheres firmly to steel surfaces, providing a continuous barrier against moisture, oxygen, and corrosive contaminants.

Removal

When the time comes for fabrication, further processing, or commissioning, WUV-25 can be easily removed using appropriate solvents or alkaline cleaners. This ensures a clean substrate is readily available without the need for aggressive mechanical preparation, saving time and reducing the risk of surface damage during removal.

Suitability for Gulf & Middle East Climates

The Gulf and Middle East region presents some of the most challenging corrosion environments in the world, combining intense UV radiation, extreme temperatures, high humidity, and salt-laden air in coastal zones. WUV-25 is engineered to withstand these conditions, making it an ideal choice for industrial buyers across Saudi Arabia, the UAE, Qatar, Kuwait, Oman, and Bahrain who need dependable, long-lasting corrosion protection for their steel assets.
