Description:
UAN Liquid Fertilizers is abbreviation of Urea Ammonium Nitrate Liquid Fertilizers. It is a solution of urea and ammonium nitrate in water. The combination of urea and ammonium nitrate has an extremely low critical relative humidity and can therefore only be used in liquid fertilizers.
Usually the Nitrate Nitrogen content is 6.5%~7.5%, Ammonium Nitrogen 6.5%~7.5%, Amide Nitrogen 14%~17%. UAN can fully take advantage of various nitrogen nutrients by concentrating three nitrogen sources in one product. Crops can absorb nitrogen source quickly from Nitrate nitrogen. Ammonium nitrogen is partially absorbed immediately by crops and partially absorbed by soil colloidality. So the UAN can supply long-term nutrients for crops whole life cycle.
Incompatibilities:
UAN will form nitrogen trichloride, which may be explosive, when mixed with chlorine and hypochlorites. If UAN solution has been dehydrated to ammonium nitrate and urea, refer to the incompatibility/decomposition information for those chemicals. UAN will form urea nitrate when mixed with nitric acid at low pH. Urea nitrate may become unstable and/or explosive under certain conditions.

Storage:
Do not use zinc or copper (brass, bronze, etc.) alloys in contact with UAN solution due to corrosion. Also, cast iron, malleable iron, or ductile iron are much more susceptible to corrosion than aluminum or carbon steel. Be especially wary of plugs and fittings on storage tanks made from these materials.
Keep away from incompatible materials or heat and fire sources. Empty containers may contain residues and may be hazardous. Do Not pressurize, cut, weld, braze, bore, grind or expose containers to heat, flame, sparks or other ignition sources; they may develop into toxic gases and cause injury or death
