Temperature
During transportation and storage, avoid exposure to light and high temperatures. The transportation and storage temperature should be between -5°C and 25°C. If the temperature drops below -5°C, insulation measures should be taken, and if it exceeds 25°C, cooling is necessary.
Sunlight
To avoid urea solution evaporation and hydrolysis, it should be stored in a sealed, light-shielded container, and protected from direct sunlight. The recommended storage period at different environmental temperatures is:
