JQSY AY‑722 high‑efficiency pre‑filming agent is mainly composed of multiple complexing agents, dispersants, film‑forming agents and surfactants. The unshared electron pairs of oxygen atoms in organic complexes generate chemical adsorption with metal ions such as iron and calcium, or partially positively‑charged iron atoms to form coordination bonds. A layer of insoluble chelating film is consequently formed on carbon steel and other metal surfaces. This high‑resistance film isolates metals from corrosive media in water so as to retard corrosion.

▲ AY‑722 features fast film formation, dense and uniform protective film, favorable chemical stability and low corrosion rate. It has strong adaptability to water quality and is immune to interference from harmful ions including copper and iron in water.
▲ As a pre‑filming agent for circulating cooling‑water systems, AY‑722 is mainly applied for pre‑filming of heat exchangers and pipelines for newly‑commissioned units or after system overhaul. It forms a protective layer on metal surfaces to prevent corrosion of carbon steel, copper alloy, stainless steel and other materials during system operation.
| Item | Specification |
|---|---|
| Appearance | Colorless to pale‑yellow transparent liquid |
| Specific Gravity (20℃, g/cm³) | 1.10±0.05 |
| Solid Content | 20 |
▲ Dosing concentration recommended by JQSY technical engineers: 1000 mg/L.
▲ Pre‑filming duration: 12‑24 hours under cold condition; 8‑16 hours under hot condition.
▲ Better performance is achieved when calcium ion content in water is no less than 50 mg/L and pH ranges from 6 to 8 during pre‑filming.
※ Packed in 25 kg plastic drums; custom packaging available upon customer request.
※ Store in cool place. Minor sediment may occur after long‑term storage, which will not affect product performance.
AY‑722 High‑Efficiency Pre‑filming Agent is weakly acidic. Take proper labor protection during operation. Avoid contact with skin and eyes. In case of contact, rinse thoroughly with plenty of clean water.
