Vanconol CPI-AP Copper Corrosion Inhibitor
1 🎯 Abstract
Vanconol CPI-AP Corrosion Inhibitor is a new generation of high-efficiency, multi-functional metal corrosion inhibitor chemically modified based on the traditional copper corrosion inhibitor tolyltriazole (TTA). By introducing piperazine active groups, this product inherits the excellent copper corrosion inhibition performance of TTA, significantly improves water solubility and dispersibility in various harsh media, and enhances the protection effect on multiple metals. It can form a denser and more stable protective film on the metal surface, thereby providing superior anti-corrosion protection, and is particularly suitable for complex water systems and working environments where traditional TTA is difficult to fully exert its effectiveness.

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 to protect heat exchanger copper tubes, pipelines and other components. The water solubility advantage ensures rapid distribution of the agent in the system, especially effective for closed circulating cooling water systems. Recommended dosage: 2-10 mg/L (based on active ingredients); for systems with existing corrosion, a 5-10 times concentration can be used for pre-film passivation in the initial stage. |
Rust Preventive Oils and Lubricating Oils | As a high-efficiency additive, it is directly soluble in rust preventive oils (greases) or lubricating oils, providing long-term vapor-phase and contact rust protection for metal components and improving the comprehensive performance of lubricating oils. |
Automotive Antifreeze | As a corrosion inhibition component, it effectively prevents corrosion of copper solder joints, brass radiators and other components in automotive cooling systems, extending the service life of the engine cooling system. |
Other Fields | It can be used as an electroplating solution additive to improve coating quality; used as a metal stabilizer in coatings and plastics, etc. |
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 with a diluted metering pump.
Initial Concentration (Pre-film Treatment): For new systems or corroded systems, it is recommended that the initial dosing concentration be 50-100 mg/L (converted to product amount), and circulate for 24-48 hours to establish a complete 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 specific dosage needs to be determined through tests according to factors such as water quality, temperature, and system materials.
Compatibility: This product can be compatible and compounded with various commonly used scale inhibitors, dispersants, and bactericidal algaecides, and often produces a synergistic effect with corrosion inhibitors such as mercaptobenzothiazole (MBT). However, before mixing with other water treatment agents (such as polymer scale inhibitors), it is recommended to conduct a compatibility test to ensure no precipitation occurs.

5 ❓ Frequently Asked Questions (FAQ)
Q: What are the core advantages of this product compared with traditional TTA?
A: The core advantages lie in three aspects: first, significantly improved water solubility, miscible with water in any ratio without pre-dissolution, suitable for automatic dosing; second, wider pH application range (5.5-10), with better corrosion inhibition effect than traditional BTA in low pH environments; third, more comprehensive protection range, not only effective for copper and copper alloys, but also has good corrosion inhibition effect on various non-ferrous metals and ferrous metals.
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); if the system has already experienced corrosion, a 5-10 times concentration can be used for passivation treatment in the initial pre-film stage.
Q: With which agents can this product be compounded? What should be noted?
A: This product can be compatible and compounded with most commonly used scale inhibitors, dispersants, and bactericidal algaecides, and can also produce a synergistic effect with corrosion inhibitors such as MBT. A compatibility test must be conducted before compounding to ensure no precipitation occurs.
Q: How to store unused products after opening?
A: This product is hygroscopic; after opening, it must be sealed in time and stored in a cool, ventilated and dry environment, avoiding direct sunlight, and used up within the 12-month shelf life.
