The "Stain Dilemma" of Traditional Rust Prevention and the Urgent Need for Clean Packaging

Whether it's the "zero-defect" requirements of automakers for body panels or the reliance on the surface insulation of silicon steel sheets in electrical equipment, the cleanliness of the metal surface directly determines the success or failure of downstream processes and the performance of the final product. While traditional rust-preventive oils can prevent rust, their inherent drawbacks are becoming increasingly apparent. However, crystalline VCI rust-preventive paper perfectly solves this problem.

Clean Type VCI Paper: The Perfect Union of Rust Prevention and Cleanliness

Core Advantage 1: Completely Eliminates Physical Contamination, Achieving "Ready to Use Out of the Box"

This insulating layer acts like a "smooth coat" for the rust-preventive paper, effectively preventing paper scraps, lint, and dust from falling off the base paper and adhering to the high-gloss steel plate surface. After unpacking, the metal surface is as clean as new, requiring no cleaning process before directly entering the stamping, painting, or assembly line, truly achieving "rust prevention without leaving a trace." This represents a revolutionary advancement for materials extremely sensitive to surface conditions, such as automotive exterior panels, high-grade chrome-plated parts, and electrical steel (oriented/non-oriented silicon steel).

Core Advantage 2: "Vacuum Phase + Barrier" Dual Intelligent Rust Prevention, Surpassing Rust-Preventive Oils

Active Vacuum Phase Rust Prevention: The VCI (Vacuum Inhibitor) contained in the paper continuously and slowly evaporates, filling the internal space of the packaging and actively adsorbing onto all metal surfaces (including complex crevices), forming a monomolecular protective layer to neutralize corrosive agents.

Physical Barrier Protection: The composite structure provides excellent water vapor barrier performance and effectively isolates oxygen and moisture from the air. Its good oil repellency and certain hygroscopicity also absorb trace amounts of moisture within the packaging space, lowering the internal dew point and fundamentally eliminating conditions for rust formation. Its rust-preventive performance has been tested and fully meets, and even exceeds, the long-term protection requirements of traditional rust-preventive oils.

Core Advantage 3: Superior Physical Strength and Environmental Safety

High-Strength Protection: The product's structure endows it with high physical strength, capable of withstanding the stacking pressure of heavy steel coils and the bumps during transportation. The packaging is not easily damaged, ensuring continuous protection.

Absolutely Safe and Environmentally Friendly: The product is non-toxic and harmless, free of phosphorus, chromates, and other heavy metals, fully complying with international environmental regulations. Compared to the flammability and handling difficulties of oils, VCI paper is safer and easier to store, use, and handle.

The emergence of Clean Type VCI Paper marks a shift in metal protection from the "necessary but troublesome" era of oils to the "efficient and clean" era of paper. It is not merely a replacement for rust-preventive materials, but an upgrade in production philosophy—by eliminating secondary pollution and cleaning processes, it saves companies overall costs, improves production efficiency, and ensures product quality.

If you are struggling with the cleaning challenges and quality risks associated with rust-preventive oils, it's time to explore this superior solution. Let Clean Type VCI Paper become your secret weapon for enhancing product competitiveness and achieving green and intelligent manufacturing.
