ATMP 50%
Amino Trimethylene Phosphonic Acid has excellent threshold scale inhibition, low dosage requirements, and superior chemical stability in recirculating cooling water systems and oilfield reinjection lines.
Technical Specification Target
Threshold Scale Inhibition Performance
ATMP functions by blocking the active growth sites of calcium carbonate crystals at sub-stoichiometric concentrations (1 to 5 ppm), inhibiting scale formation even in supersaturated cooling water.
When combined with polycarboxylic dispersants (such as PAA or PMA), it provides powerful synergistic scale control across open recirculating cooling loops.
Standard Industrial Dosage

| Open Cooling Towers | 1.0 – 10.0 ppm |
| Oilfield Waterflooding | 10.0 – 20.0 ppm |
| Industrial Cleaners & Descalers | 1.0 – 5.0% |

Frequently Asked Questions: ATMP 50%
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is ATMP 50% and how does it prevent scale?
ATMP (Amino Trimethylene Phosphonic Acid, CAS 6419-19-8) is a classic organophosphonate threshold inhibitor that blocks calcium carbonate scale nucleation at sub-stoichiometric dosages.
Q2. What is the typical dosage of ATMP in industrial cooling water?
Continuous dosing of 1.0 to 10.0 ppm active is typical for open recirculating cooling systems. In oilfield waterflooding, 10.0 to 20.0 ppm is applied.
Q3. What is the active purity and density of ZEELCHEM™ 111 ATMP?
ZEELCHEM™ 111 contains ≥50.0% active ATMP with a specific gravity of 1.32–1.35 g/cm³ and low phosphorous acid content (≤3.0%).
