HEDP 60, Hydroxyethylidene Diphosphonic Acid 60%
HEDP 60% is an organic phosphonic acid with multifunctional properties. It provides control of calcium and other metal salts including iron and manganese by acting as a strong crystal modifying agent and threshold inhibitor. Like sequestration of hardness salts and heavy metals, deflocculation, threshold inhibition and hydrolytic stability as a single active ingredient. Because of the combination of these properties. HEDP 60 has a wide range of applications as a scale and corrosion inhibitor.
HEDP 60% is a sequestrant and excellent deposit control agent.
Based on its hydrolytic stability, superior anti-scaling and sequestering ability, HEDP acid 60% is known as a superior phosphonic acid chelating agent in the market. Owing to their anti-scaling and hydrolytic stability, These products are generally used in water treatment, soaps & detergents and sugar processing.
