Product introduction of Volatile corrosion inhibitor:
Volatile corrosion inhibitor produced by CVCI is made of high-efficiency vapor phase corrosion inhibitor and a variety of high-efficiency active adsorbents as raw materials. It is a scientifically formulated product that organically combines vapor phase rust prevention and dry packaging. It has excellent gasification and high-efficiency adsorption performance. Corrosion Inhibitor VCI Additive can be used for dry moisture-proof and rust-proof treatment of products in industries such as electronics, metal products, precision machinery, communications, military industry, building materials, and instruments.
Product advantages of Corrosion Inhibitor VCI Additive:
The Corrosion Inhibitor VCI Additive we produce has good anti-rust effect and strong moisture absorption capacity. It can release anti-rust ingredients while absorbing moisture, effectively protecting metal from rust. The packaging of anti rust powder VCI Desiccant adopts a sturdy double-layer structure of DuPont paper and non-woven fabric, which is not easy to break and is safer to use. Corrosion Inhibitor VCI Additive ingredients are safe, do not contain harmful substances, meet environmental protection requirements, and are suitable for export or precision products with environmental protection requirements.
Product application:
Electronic industry: Anti rust powder VCI Desiccant can be used for moisture-proof and rust-proof protection of circuit boards, chips, connectors and other products to prevent moisture and oxidation.
Metal products industry: Volatile corrosion inhibitor is suitable for packaging and rust-proofing of metal parts such as screws, knives, and hardware.
Precision machinery industry: used for long-term protection of high-precision parts such as precision bearings, gears, and molds.
Communication industry: suitable for anti-corrosion treatment of metal components and connectors inside communication equipment.
Building materials industry: can be used for moisture-proof and rust-proofing of steel, profiles, metal doors and windows and other building materials during transportation and storage.
Customer cooperation:
A car parts manufacturer regularly exports precision-machined parts to Thailand and Vietnam. Due to the typically longer sea freight time (over 30 days), condensation was a common problem inside the packaging. The customer initially used only ordinary silica gel desiccant, but occasional rust complaints still occurred during rainy season transport. After adopting VCI Desiccant from CVCI in conjunction with VCI packaging materials, the internal humidity of the packaging significantly decreased, the rust complaint rate during sea freight dropped by approximately 75%, and the product storage period stabilized at over 12 months. This solution has now become one of the customer's standard export packaging configurations.

Why must Volatile corrosion inhibitor be used?
If anti rust powder VCI Desiccant is not used during storage or transportation, metal products are prone to oxidation and rust due to moisture, water vapor intrusion or temperature changes, resulting in surface discoloration, spotting and corrosion, which in severe cases will affect the matching accuracy and performance of parts. Especially precision machinery, electronic products, hardware parts, etc. are extremely sensitive to humidity. Rusting not only affects the appearance, but may also cause functional failure or scrapping, increase rework and loss costs, and even affect customers' trust in product quality. Using Volatile corrosion inhibitor is a simple, economical but very effective way of protection.
