DEF is a reactant that's key to the SCR process. It's a nontoxic, ultra-pure solution of urea and ultra-pure water. Urea is a
compound of nitrogen that turns to ammonia when heated. It is used in a variety of industries, perhaps most commonly as a
fertilizer in agriculture. The fluid is non flammable, and is not dangerous when handled as recommended. However, it is
highly corrosive to certain metals, especially copper and brass. Read the separate section concerning the handling of DEF
solution.
