AMP is a 50% active aqueous solution of aminotris (methylene phosphonic acid), AMP. It provides control of calcium and other metal salts including iron and manganese by acting as a crystal modifying agent and threshold inhibition. AMP is know to be a sequestrant and deposit control agent due to its dispersing and deflocculating characteristics.
