Property and Uses

PESA is a green, environmentally friendly, multi-purpose scale and corrosion inhibitor that is phosphorus-free and nitrogen-free. It has excellent scale inhibition and dispersion properties for calcium carbonate, calcium sulfate, and barium sulfate in water, with scale prevention better than commonly used organic phosphine scale inhibitors. It has a good synergistic effect when combined with phosphates. It also has certain corrosion inhibitors and is a multi-purpose scale inhibitor.
It has good biodegradability and a wide range of applications, especially suitable for cooling water systems under high alkaline, high hardness, and high pH conditions, enabling operation at high concentration ratios. It has good compatibility with chlorine and compatibility with other chemicals.
