Vanconol CPI-42 Copper Corrosion Inhibitor
1. 🎯 Abstract
Vanconol CPI-42 Corrosion Inhibitor is a new generation of high-efficiency water-soluble metal corrosion inhibitor modified by diethanolamine from the classic copper corrosion inhibitor benzotriazole (BTA) through advanced molecular design. It effectively solves the pain points of poor water solubility and inconvenient use of traditional BTA. It can form a dense and firm adsorption protective film on the metal surface, and can provide excellent anti-corrosion protection for multi-metal systems in many fields such as industrial water treatment and metal processing. It also has a wide range of applicable working conditions and good environmental compatibility.

Automotive Antifreeze and Engine Coolants | As a key corrosion inhibition component, it effectively prevents electrochemical corrosion and pitting corrosion of copper solder joints, brass radiators and other components in automotive cooling systems, extending the system life. |
Metalworking Fluids and Lubricants | As a high-efficiency corrosion inhibition additive, it is used in cutting oils, drilling fluids, hydraulic oils and other industrial lubricants to protect processing equipment and workpieces from rust. |
Other Fields | It can be used in boiler water treatment systems, formulations for acid gas purification processes (such as removal of H₂S, CO₂), and as an intermediate for surfactant synthesis. |
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 (Pretreatment Film Formation): 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 through tests according to specific water quality (pH, hardness, chloride ion content), temperature, concentration multiple and other factors.
Compatibility: This product can be compatible and compounded with most commonly used scale inhibitors, dispersants and bactericidal algaecides. However, when preparing composite agents, it is recommended to conduct compatibility tests first to ensure no precipitation occurs.
4. ⚠️ Safety and Storage
Packaging: 25kg, 200kg plastic drums, or customized according to customer requirements.
Storage: Store in a sealed, cool, ventilated and dry place, avoiding direct sunlight. This product is hygroscopic; please seal it tightly after opening.
Shelf Life: 12 months.
Safety Precautions: Wear appropriate personal protective equipment such as protective gloves and goggles during operation. If it comes into contact with the skin, immediately rinse thoroughly with soapy water and clean water; if it comes into contact with the eyes, immediately rinse with a large amount of clean water for at least 15 minutes and seek medical attention in time. 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 advantages of this product compared with traditional BTA?
A: The biggest advantage of this product is its excellent water solubility, which can be directly dosed without organic solvents or strong alkalis for dissolution; at the same time, it has higher corrosion inhibition efficiency, can protect multiple metals, has a wider pH adaptation range, and is more environmentally friendly and safe.
Q: How to determine the optimal dosage of this product?
A: The initial pre-film concentration is recommended to be 50 - 100 mg/L (based on the product), and the maintenance concentration during normal operation is 2 - 10 mg/L (based on active ingredients). The final optimal dosage needs to be determined through tests in combination with actual water quality, temperature, concentration multiple and other factors.
Q: With which agents can this product be compounded?
A: This product can be compatible and compounded with most commonly used scale inhibitors, dispersants and bactericidal algaecides, but compatibility tests are required before compounding to ensure no precipitation occurs.
Q: How to handle unused products after opening?
A: This product is hygroscopic; it needs to be sealed tightly in time after opening, stored according to the specified storage conditions to avoid affecting product performance, and used up within the shelf life.
