Product overview
ZEELCHEM™ 111 is ATMP (amino trimethylene phosphonic acid, also called NTMP) supplied as a 50 % solution. It has excellent chelating ability, very good threshold inhibition of calcium carbonate scale and lattice-distortion activity, and markedly better hydrolytic stability than inorganic polyphosphates.
ATMP is one of the most cost-effective phosphonates for controlling carbonate scale in cooling water and low-pressure boilers. At higher doses it also provides corrosion inhibition, particularly in combination with zinc salts, and it is widely blended with HEDP and polymers in multifunctional treatment programmes.
Its strong sequestering power for iron, copper and alkaline-earth metals also makes ATMP useful in textile and dyeing auxiliaries, detergent formulations, metal surface treatment and as a component of RO antiscalants.

Dosage & method of use
1 – 20 mg/L as a scale inhibitor; 20 – 60 mg/L as a corrosion inhibitor in combination with zinc or other inhibitors. Dosage should be confirmed from water analysis.
Dosing calculator
Estimates only. Evaporation is calculated as E = 0.00153 × R × ΔT (°C); blowdown B = E ÷ (COC − 1); product feed for cooling towers = B × dose. The right dose depends on your water analysis, metallurgy and operating conditions. Our technical team will confirm it free of charge.
Packaging
65.0 kg net HDPE carboy. Each carboy is labelled with product name, batch number, net weight and GHS hazard information.
Storage & shelf life
Store in original closed HDPE / stainless-steel containers in a cool, dry, well-ventilated and shaded area away from strong alkalis and oxidisers. Avoid freezing and prolonged direct sunlight. Shelf life: 12 months in unopened packing.
Handling & safety
Acidic product. Wear chemical goggles, nitrile/PVC gloves and protective clothing. In case of eye or skin contact, rinse with plenty of water for at least 15 minutes and seek medical advice. Refer to the ZEELCHEM™ SDS (GHS / CLP format) before handling.
Frequently asked questions
What is ATMP used for?
ATMP is used as a scale inhibitor and chelating agent in cooling water, boilers, oilfields, textile processing, detergents and metal treatment.
Is ATMP the same as NTMP?
Yes. ATMP (amino trimethylene phosphonic acid) is also known as NTMP (nitrilotris(methylene phosphonic acid)), CAS 6419-19-8.
Which is better, ATMP or HEDP?
ATMP is a highly cost-effective carbonate inhibitor; HEDP gives better high-temperature and corrosion performance. Many programmes use both together.
What is the typical dosage of ATMP 50?
1–20 mg/L (ppm) as product in cooling water; the final dose depends on water analysis. Use the dosing calculator on this page.
