Relative molecular mass: 400-1500

Structural formula:

Performance and Applications:

PESA It is phosphorus-free and nitrogen-free. “ Green ” An environmentally friendly, multi‑functional scale inhibitor and corrosion inhibitor. It exhibits excellent scale‑inhibition and dispersing performance against calcium carbonate, calcium sulfate, and barium sulfate in water, with superior scale‑inhibition efficacy compared to conventional organic phosphonate inhibitors. When compounded with phosphonates, it delivers significant synergistic enhancement, while also providing a degree of corrosion inhibition, making it a versatile scale‑inhibiting agent.

PESA It exhibits excellent biodegradability and a wide range of applications, particularly suitable for high-alkalinity, high-hardness, and high… conditions. pH Under these conditions, the cooling water system can operate at a high concentration ratio; it exhibits excellent compatibility with chlorine and good miscibility with other chemical agents.

Instructions for use:

PESA Suitable for applications such as oilfield water injection and boiler water treatment; applicable to circulating cooling water systems in industries including steel, petrochemicals, power generation, and pharmaceuticals; particularly well-suited for conditions characterized by high alkalinity, high hardness, and high… pH — Boiler water treatment, circulating cooling water treatment, seawater desalination, membrane separation, and other fields in high‑concentration‑ratio systems; suitable for the detergent industry.

PESA When used in the water treatment field, the typical dosage is 10 ~ 30mg/L， PESA When used as a dispersant, the recommended dosage is

0.5-3.0% The specific dosage can be determined through experimentation. As this product is anionic, it should not be used in combination with cationic chemical auxiliaries.

Packaging and Storage:

PESA Packaged in plastic drums, each drum 25kg or 250kg , or determined according to user requirements. Store in a cool, shaded area; shelf life is ten months.

Security Protection:

PESA It is a non‑toxic, non‑irritating substance that poses no harm to flora and fauna in the environment.
