ATMP 50 — Amino Trimethylene Phosphonic Acid
Also known as: Amino tris(methylene phosphonic acid), Aminotrimethylene phosphonic acid, NTMP, ATMPA
Amino tris(methylene phosphonic acid) — an economical, high-performance calcium carbonate scale inhibitor and sequestrant.
- Cost-effective CaCO₃ scale inhibition
- Strong sequestering power
- Better hydrolytic stability than polyphosphates
- Synergistic with HEDP and polymers
What is ATMP?
ATMP (amino tris(methylene phosphonic acid), CAS 6419-19-8) is a low-cost phosphonate scale inhibitor and sequestrant. At 1–20 mg/L it keeps calcium carbonate in solution in cooling water and oilfield systems and stabilises peroxide in textile bleaching. ZEELCHEM supplies ATMP 50% in 65 kg carboys.

ATMP overview
ATMP 50 offers excellent chelation and low threshold inhibition, so very small doses keep calcium carbonate in solution. It resists hydrolysis better than inorganic polyphosphates, giving a reliable residual in hot water.
It is used in industrial cooling water, oilfield water, industrial cleaning and textile bleaching, and pairs well with HEDP and polycarboxylate polymers.
How ATMP works
ATMP's three phosphonic groups give strong threshold inhibition of calcium carbonate and good chelation of iron and copper; it resists hydrolysis far better than inorganic polyphosphates, so it keeps working in hot water.

Handling, storage and safety
Acidic liquid: causes eye and skin irritation. Wear chemical goggles, nitrile or PVC gloves and an apron; keep an eyewash nearby. Store in the original closed HDPE carboy, in shade, at 5–40 °C, away from strong alkalis and oxidisers. Do not store in mild-steel or aluminium containers. Rinse spills with plenty of water.
Shelf life: 24 months in sealed containers.
