Vanconol® ALI-1214 Corrosion Inhibitor
----------For Aluminum Alloy
1 🎯 Abstract
Vanconol® ALI-1214 Phosphate Ester Corrosion Inhibitor is an anionic corrosion inhibitor obtained by phosphorylation of natural fatty alcohol polyether. Its molecular structure combines the strong adsorption of phosphate groups and the excellent water solubility of polyoxyethylene ether chains, which can form a dense adsorption film on the aluminum alloy surface, effectively inhibiting corrosion, blackening, white fuzz and other problems caused by moisture, acid and alkali media during processing. This product is environmentally friendly and low-toxic, resistant to hard water and high temperature, and has good compatibility with various additives, making it an ideal corrosion inhibition additive in aluminum alloy processing fluids.

3 🛠️ Performance Characteristics
High-Efficiency Corrosion Inhibition: Forms a protective film through chelation between phosphate groups and the aluminum surface, preventing pitting corrosion, discoloration (such as blackening, graying) or loss of luster of aluminum alloy in processing fluids.
Wide Environmental Adaptability: Resistant to acid, alkali and hard water (stable at pH 6–12), and maintains activity in high-temperature (≤90℃) and high inorganic salt environments.
Multifunctional Synergy: Integrates lubrication, emulsification, dispersion and antistatic functions, which can reduce the dosage of other additives in processing fluids.
Environmental Safety: Good biodegradability, free of restricted substances such as APEO and heavy metals, and low skin irritation.
Strong Compatibility: Has good compatibility with anionic/non-ionic surfactants (such as alcohol ethers, sulfonic acids), bactericides, scale inhibitors, etc.
4 📝 Application Fields
Aluminum Alloy Processing Fluids: Used as rust inhibitor and corrosion inhibitor in cutting fluids, grinding fluids and lapping fluids.
Metal Cleaners and Pretreatment: Used as rust inhibitor and corrosion inhibitor in degreasers and cleaning fluid formulations.
Forming Processes and Special Lubrication: Used as corrosion inhibitor, extreme pressure agent and lubricant in cold rolling emulsions, stamping fluids, wire drawing oils and lubricating oil formulations.
Other Fields: Used as an additive in rust-preventive chemicals.
5 🧪 Application Recommendations
5.1 Aluminum Alloy Processing Fluid Formulation
Dosage: The recommended dosage is 0.2%-3% of the total formula (adjust according to water quality and processing conditions).
Compound Example:
Basic Formula: ALI-1214 Phosphate Ester (3%) + Triethanolamine Borate (1%) + Lubricant (3%) + Deionized Water (balance).
For high-alkaline environments, phosphorus-free corrosion inhibitors can be used in combination to enhance protection.
5.2 Service Conditions
Optimal pH Range: 6.0–9.5 (the corrosion inhibition film has the highest stability within this range).
Temperature Limit: Long-term service temperature ≤80℃; avoid direct mixing with strong oxidants.
6 ⚠️ Safety and Storage
Packaging: Sealed packaging in 50kg/200kg plastic barrels.
Storage: Store in a cool and well-ventilated place, avoid direct sunlight; shelf life is 2 years.
Safe Operation: Wear protective gloves during use; if splashed into eyes, immediately rinse with clean water and seek medical attention.
7 ❓ Frequently Asked Questions (FAQ)
Q1: Is ALI-1214 Corrosion Inhibitor suitable for all aluminum alloy materials?
