ATMP Properties

Amino Trimethylene Phosphonic Acid (ATMP) is a highly effective phosphonic acid-based scale and corrosion inhibitor with the following characteristics:

Functionality

Strong chelation of Ca²⁺, Mg²⁺, Fe²⁺/Fe³⁺, even at low concentrations (1–10 ppm).

Effective scale inhibition (e.g., CaCO₃, CaSO₄, BaSO₄) and corrosion protection for metals.

Synergistic effects when combined with HEDP or PBTC for enhanced performance.

ATMP Applications

Widely used as a cost-efficient scale and corrosion inhibitor in:

Water Treatment

Cooling/Boiler Systems: Prevents CaCO₃ and CaSO₄ scaling at 2–15 ppm.

RO Membranes: Reduces metal ion fouling (Fe³⁺, Al³⁺).

Industrial Cleaning

Acid Cleaning (HCl/H₂SO₄): Added at 0.1–0.3% to inhibit metal corrosion (steel, copper) during descaling.

Textile Processing: Controls metal ion interference in dyeing baths.

Oilfield Chemistry

Scale Inhibition: Controls BaSO₄/SrSO₄ deposition in produced water (≤80°C)

Other Uses:

Pulp/Paper Industry: Stabilizes hydrogen peroxide bleaching.

Detergents: Acts as a builder to soften hard water.
