ATMP possesses excellent chelating, threshold‑inhibiting and crystal‑distortion effects. It can prevent scale‑forming salts from generating water scale, especially calcium carbonate scale. It features favorable chemical stability and is resistant to hydrolysis in water. It delivers good corrosion‑inhibition performance at relatively high concentration in aqueous solution.
Alias: ATMP

ATMP is usually compounded with other organic phosphonic acids, polycarboxylic acids or their salts to formulate organic water treatment agents for circulating cooling‑water systems under various water‑quality conditions. The recommended dosage is 1‑20 mg/L. When used as corrosion inhibitor, the dosage ranges from 20‑60 mg/L.
Liquid ATMP is packed in plastic drums, 30 kg or 250 kg per drum. Solid ATMP is packed in plastic woven bags with inner polyethylene liner, 25 kg per bag. Customized packages are available upon customer requirements. Store indoors in cool and well‑ventilated place, keep away from moisture and direct sunlight. Shelf life: 10 months.
ATMP is acidic. Take labor‑protection measures during operation. Avoid contact with skin and eyes. Rinse immediately with plenty of clean water in case of contact.
