Corrosion Inhibitors
Corrosion Inhibitors for liquid fertilizers
Kao is a key partner for UAN producers through our production of corrosion inhibitors within SK FERT technology.
In addition to research activity, Kao has performed product optimization with different particle sizes to ensure smooth application and provide additives sensitive to UV light for better application control. This application methodology is a key factor in its success and, as always, comes with Kao technical services and recommendations.
Urea ammonium nitrate (UAN) is very popular source of nitrogen fertilizer. UAN fertilizer delivers a high concentration of both fast and slow release nitrogen nutrients in an aqueous form that can be stored at reasonable ambient temperatures.
The disadvantage of UAN is that it is usually highly corrosive to storage tanks, pipes, rail cars, and agricultural application equipment. It makes the addition of an effective corrosion inhibitor crucial.
Why is a corrosion inhibitor essential?
• Prevents damaging corrosion of carbon steel
• Decreases maintenance and downtime costs
• Minimizes discoloration and sludge formation
• Extremely effective for storage facilities and farming equipment
• Allows storage for long periods
