Corrosion is one of the leading causes of damage to metal surfaces in many industries. From manufacturing to construction, marine, and power sectors, businesses across the globe are seeking innovative solutions to protect their assets from the detrimental effects of rust and corrosion. Traditional methods often fall short in delivering long-lasting protection, especially in extreme environments. In response to this growing need, VCI EP NEW MATERIALS (SHANGHAI) CO., LTD. has introduced two groundbreaking products: VCI-901 Water-Based Rust Converter and VCI-902 Silicone Coating. These two innovations, leveraging the power of VCI technology, are designed to provide superior protection for metal surfaces, ensuring longevity and durability.
Corrosion remains one of the most significant threats to the longevity of metal surfaces, especially in industries dealing with harsh environmental conditions. From the aerospace industry to marine, chemical, and energy sectors, the cost of corrosion—both in terms of material damage and maintenance—is substantial.
Traditional rust prevention methods, such as oil-based coatings, zinc-rich primers, and chemical desiccants, have long been relied upon to protect metal parts. However, these solutions often fall short in terms of effectiveness, environmental impact, and ease of application. This is where VCI technology plays a crucial role.
VCI (Volatile Corrosion Inhibitor) technology offers a scientifically advanced approach to corrosion prevention. By utilizing vapor-phase molecules, VCI products form a protective layer on metal surfaces, preventing rust without the need for oil coatings or abrasive cleaning. In this article, we will delve into the VCI-901 Water-Based Rust Converter and VCI-902 Silicone Coating, highlighting their innovative features and how they offer a more effective, sustainable solution to corrosion protection.
The VCI-901 Water-Based Rust Converter is a state-of-the-art solution designed to remove rust and provide long-term corrosion protection for metal surfaces. Unlike traditional rust removers, VCI-901 does not require sanding or abrasive cleaning, making the process simpler and more efficient.
Polymer Emulsion Technology: VCI-901 uses advanced polymer emulsions that combine metal chelation, passivation, and rust inhibition into a single solution.
Rust Transformation: The product chemically transforms iron oxide (rust) into a stable crystalline film that binds to the metal surface, providing a robust protective layer.
Eco-Friendly and Non-Toxic: VCI-901 is water-based, free from harmful solvents and toxic chemicals, making it an environmentally safe alternative to traditional rust removers.
No Need for Abrasive Cleaning: Traditional rust removal methods often require abrasive techniques or acid washes, which can be time-consuming and damaging to the metal surface. VCI-901 eliminates the need for such processes, making rust removal faster and easier.
Long-Term Rust Protection: Once applied, VCI-901 not only removes rust but also provides lasting corrosion protection, forming a stable chelate that inhibits further rust formation.
Versatile Application: VCI-901 can be used across a wide range of industries and applications, from automotive and construction to heavy machinery and more.
Environmentally Safe: Unlike many traditional rust converters, VCI-901 is free from harmful VOCs (volatile organic compounds), offering a green solution for industries seeking environmentally friendly alternatives.
When VCI-901 is applied to a rusty metal surface, it chemically reacts with the rust (iron oxide) to form a stable crystalline film. This film not only removes the rust but also bonds with the metal, forming a protective layer that prevents further oxidation.
The rust converter works in three stages:
Rust Transformation: VCI-901 turns the iron oxide into a stable crystalline layer.
Chelation: The chelating agents in VCI-901 bind with the rust particles, stabilizing them and preventing further corrosion.
Passivation: The final passivating layer protects the metal surface from external corrosive agents, ensuring long-term rust protection.
Time and Cost Efficiency: No need for complex cleaning or abrasive methods. Apply VCI-901 directly to the rusty surface and let it work.
Eco-Friendly: Non-toxic, water-based formula ensures minimal environmental impact.
Comprehensive Protection: Provides both rust removal and long-term corrosion protection in one step.
The VCI-902 Silicone Coating is a high-performance corrosion protection solution designed for industries operating in extreme environments. Specially formulated for metal surfaces exposed to harsh conditions such as high temperatures, salt water, and UV radiation, VCI-902 provides superior protection against corrosion and degradation.
High-Temperature and Low-Temperature Resistance: VCI-902 performs well in a broad range of temperatures, from extremely high to low temperatures, making it ideal for industries that require versatile protection.
UV and Salt Mist Resistance: The coating also offers exceptional resistance to UV radiation and salt mist, ensuring durability in outdoor and marine environments.
Electrical Insulation: VCI-902 also serves as an electrical insulator, making it suitable for use on electronic components and electrical parts.
Superior Durability: With outstanding resistance to corrosion, UV radiation, aging, and temperature extremes, VCI-902 provides long-lasting protection for metal surfaces.
Chemical Resistance: VCI-902 offers excellent resistance to water, oils, and various chemicals, ensuring reliable protection in a wide range of industrial environments.
Excellent Adhesion: This silicone coating adheres well to most metal surfaces, ensuring a secure and lasting protective layer.
Versatile Applications: VCI-902 is designed for use in construction, marine, chemical, and power industries, where equipment is exposed to harsh environmental conditions.
VCI-902 is designed to protect metal surfaces in environments that demand high performance. Key applications include:
Marine Industry: Protecting boats, ships, and offshore platforms from saltwater corrosion.
Construction: Shielding metal infrastructure from environmental exposure.
Power Plants: Providing protection for electrical components and machinery in power generation facilities.
Chemical Industry: Protecting metal equipment from chemical exposure.
When used together, VCI-901 and VCI-902 provide an integrated corrosion protection solution that offers both chemical bonding and physical shielding. This dual approach ensures enhanced protection that lasts longer than traditional methods.
Chemical Bonding: VCI-901 forms a stable bond with the metal surface, neutralizing rust and preventing further corrosion.
Physical Shielding: VCI-902 provides an additional physical barrier, shielding the metal from moisture, salt, UV radiation, and other corrosive elements.
The combination of both products creates a multi-layered protective system that dramatically extends the corrosion protection cycle. The effectiveness of this solution has been tested through rigorous salt spray testing, showing impressive results:
Salt Spray Test: VCI-902 has exceeded 1000 hours of salt spray resistance, significantly outperforming traditional coatings that only last 300-400 hours.
Protection Period: Combined use of VCI-901 and VCI-902 provides corrosion protection for up to 10 years, compared to just 3-5 years for traditional systems.
Traditional anti-corrosion methods, such as epoxy zinc-rich coatings, epoxy coal tar, and polyurethane coatings, have been widely used in the industry. However, they come with various limitations:
Shorter Protection Lifespan: Typically, traditional systems offer only 3-5 years of protection, and they may require regular maintenance.
Environmental Impact: Many traditional coatings contain harmful solvents and VOCs that pose environmental hazards.
Complex Application: Traditional systems often require multiple layers, sanding, or abrasive cleaning, making the application process time-consuming and costly.
