AdBlue is a highly purified colorless liquid. It contains demineralized water and urea (32.5%).
AdBlue is used with diesel engines and is also known outside of Europe as DEF, ARLA 32 or AUS 32.
The main active component of AdBlue is ammonia. This is chemically formed by hydrolising automotive urea, which is the main raw material for AdBlue.
