VCI Powder For Polymetal
1. Corrosion Anti Rust Packaging has excellent gasification, diffusion and adsorption properties.
2. After the Corrosion Anti Rust Packaging is vaporized, it is adsorbed on the protected metal surface to form a protective layer, which can effectively prevent the corrosion of the metal surface, especially applicable to the rust prevention of the metal surface that is difficult to reach, such as deep holes, thin pipes, twists and cracks.

Product description of Corrosion Anti Rust Packaging:
VCI Powder for Polymetal (SF/D331L) is a vapor-phase corrosion inhibitor powder designed for multi-metal protection. It has been specifically developed to address the long-term rust prevention requirements of complex structures, enclosed spaces, and difficult-to-access areas. The product exhibits excellent vaporization, diffusion, and adsorption capabilities; within a sealed environment, it continuously releases VCI inhibitor molecules to form a molecular-level protective layer on metal surfaces, thereby effectively mitigating the risks of oxidation and corrosion. Corrosion Inhibitor Powder Multimetal is a highly efficient vapor phase anti-rust powder designed for complex structures, with excellent gasification, diffusion and adsorption properties. After being gasified in a closed environment, Corrosion Inhibitor Powder Multimetal can actively adsorb on the metal surface to form a dense protective film, effectively preventing rust. Corrosion Inhibitor Powder Multimetal is particularly suitable for deep holes, slender tubes, gaps and other places that are difficult to reach by traditional methods, and is suitable for long-term sealing and protection of a variety of metal materials.

Features of VCI Anti Rust White Powder:
VCI Anti Rust White Powder has excellent gasification performance, which can quickly release vapor phase anti-rust molecules in a sealed space, fully covering the metal surface, and is suitable for high-demand anti-rust applications.
As a flexible Corrosion Inhibitor Powder Multimetal, this product can be used in hanging bags or directly sprayed, suitable for sealing and protecting metal parts of different shapes and sizes.
There is no cleaning requirement for the metal surface when using hanging bags. It is easy to remove after spraying, leaving no residue and not affecting subsequent processing. It is an ideal Corrosion Anti Rust Packaging solution.
Designed for a variety of metals such as steel, copper, aluminum, and stainless steel, Corrosion Inhibitor Powder Multimetal can maintain a stable anti-rust effect in complex environments.
Using VCI Anti Rust White Powder can greatly reduce the risk of corrosion on the metal surface during storage and transportation, and increase the overall shelf life of the product.
VCI Anti Rust White Powder has passed the RoHS test and meets EU environmental standards. It is a safe and reliable Corrosion Anti Rust Packaging material suitable for global export needs.

Instructions of VCI Anti Rust White Powder:
VCI Anti Rust White Powder is very easy to use. Just place the anti-rust bag in a closed space near the metal product to be protected and keep it well sealed. The effective distance of the powder after vaporization can reach 30 cm. As a highly efficient Corrosion Inhibitor Powder for Multimetal, the recommended usage is 100 grams per cubic meter of space. The dosage can be appropriately increased in harsh environments such as high humidity or sea transportation. The protection period can be up to 12 months. This product is suitable for various Corrosion Anti Rust Packaging scenarios, and the packaging materials should be well sealed. Please store in a cool and ventilated place during storage. Refer to the chemical storage standards. The product is valid for one year.
