Vanconol CPI-MI Copper Corrosion Inhibitor
1 🎯 Abstract
Vanconol CPI-MI Corrosion Inhibitor is an imidazoline-modified benzotriazole corrosion inhibitor, a new generation of high-efficiency metal corrosion inhibitor optimized in molecular structure based on traditional benzotriazole (BTA). By introducing imidazoline active groups, this product retains the excellent copper corrosion inhibition performance of BTA, significantly improves water solubility, and enhances the protection effect on various metals such as steel. It solves the problems of traditional BTA's limited water solubility (about 25g/L at 20℃) and main applicability to copper and copper alloys. It can form a denser and more stable protective film on the metal surface, providing comprehensive anti-corrosion protection for multi-metal systems.

3 🛠️ Application Guide
3.1 Recommended Application Fields
Application Field | Application Scenarios and Efficacy Description |
Industrial Circulating Cooling Water Systems | As a core corrosion inhibitor, it is used in open or closed circulating cooling water systems, especially suitable for heat exchange systems containing copper tubes and carbon steel equipment. Its excellent water solubility ensures rapid and uniform distribution of the agent, providing effective protection for copper alloys and carbon steel simultaneously. Recommended dosage: 2-10 mg/L (based on active ingredients). |
Rust Preventive Oil and Lubricating Oil Additives | As a high-efficiency multi-functional additive, it is integrated into rust preventive oils (greases), extreme pressure industrial gear oils, anti-wear hydraulic oils, greases and other products to provide comprehensive rust and corrosion protection for metal components. |
Automotive Antifreeze | As a key corrosion inhibition component, it is used in automotive engine coolants, effectively preventing corrosion of various metals in the cooling system such as copper solder joints, brass radiators, steel components and aluminum cylinder blocks. |
Other Fields | 1. Metalworking Fluids: Used as a corrosion inhibitor in cutting oils, emulsions, etc., to prevent rust of workpieces; 2. Electroplating and Surface Treatment: Used as a chromium mist inhibitor during electroplating to improve the brightness of plated parts, and also for anti-discoloration treatment of metal surfaces; 3. Coatings and Polymer Materials: Used as an ultraviolet absorber (absorbing wavelength 290-390 nm) in outdoor coatings, plastics, etc., to prevent light aging and yellowing of materials. |
3.2 Usage Methods and Recommended Dosage
Dosing Method: This product is a water-soluble liquid, which can be directly poured into the system or continuously and accurately dosed through a metering pump after dilution.
Initial Concentration (Pre-film Treatment): For new systems or systems that have been cleaned but not pre-filmed, it is recommended that the initial dosing concentration be 50 - 100 mg/L (based on the product), and circulate for 24-48 hours to establish a complete and dense protective film.
Maintenance Concentration: During normal operation, it is recommended to maintain the concentration of this product in water at 2 - 10 mg/L (based on active ingredients). The optimal dosage needs to be determined according to specific water quality (pH, hardness, chloride ion content), temperature, system materials and other factors.
Compatibility: This product can be compatible and compounded with most commonly used water treatment agents (such as scale inhibitors, dispersants, bactericidal algaecides). However, when preparing composite agents, it is recommended to conduct compatibility tests first.
4 ⚠️ Safety and Storage
Packaging: 25kg, 200kg plastic drums, or customized according to customer requirements.

Safety Precautions: Wear appropriate personal protective equipment during operation. If it comes into contact with skin or eyes, immediately rinse with a large amount of clean water. For detailed safety information, please refer to the Safety Data Sheet (SDS) of this product.
5 ❓ Frequently Asked Questions (FAQ)
Q: What are the core improvements of this product compared with traditional BTA?
A: The core improvements lie in two aspects: first, significantly improved water solubility, solving the problem that traditional BTA needs to be dissolved with organic solvents or strong alkalis, and can be directly dosed; second, expanded protection range, which is not only effective for copper and copper alloys, but also has excellent corrosion inhibition effect on ferrous metals such as steel and galvanized steel, suitable for multi-metal systems.
Q: What is the recommended dosage of this product in industrial circulating cooling water systems?
A: The maintenance concentration during normal operation is 2-10 mg/L (based on active ingredients); for new systems or cleaned but not pre-filmed systems, the initial dosing concentration is 50-100 mg/L (based on the product), and circulate for 24-48 hours for pre-filming.
Q: With which agents can this product be compounded? What should be noted when compounding?
A: It can be compatible and compounded with most commonly used scale inhibitors, dispersants and bactericidal algaecides. Compounding with copolymers such as organophosphonates can also significantly improve the overall corrosion and scale inhibition effect. It is recommended to conduct compatibility tests before compounding to ensure no abnormal reactions.
Q: Does this product have other additional functions besides corrosion inhibition?
A: Yes. This product can be used as an ultraviolet absorber (absorbing wavelength 290-390 nm) in outdoor coatings, plastics and other products to prevent light aging and yellowing of materials; at the same time, it can be used as a chromium mist inhibitor during electroplating to improve the brightness of plated parts.
