Hydroxyphosphono-acetic acid (HPAA)
HPAA will be delivered as a 50% aqueous solution. The product is considered being a mild steel corrosion inhibitor and is mainly used in the water treatment industry. It shows superior performance in all organic formulations compared to commonly used Phosphonates. In certain formulations it can replace Molybdate or its derivatives.
Applications:
Cooling water systems / industrial water treatment
Metal surface treatment as corrosion inhibitor for steel
Usage:
HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.
