ATMP (Amino Trimethylene Phosphonic Acid) - High-Efficiency Scale & Corrosion Inhibitor for Water Treatment

ATMP (Amino Trimethylene Phosphonic Acid) is a highly effective organic phosphonic acid scale and corrosion inhibitor. It exhibits excellent chelation ability and low threshold inhibition, making it a key component in industrial water treatment formulations to protect systems from scale formation and metal corrosion.

Key Features & Benefits:

1. High-Efficiency Scale Inhibition:​ Demonstrates superior performance in inhibiting the formation of carbonate, sulfate, and phosphate scales, particularly effective against calcium carbonate scale.
2. Excellent Corrosion Control:​ Forms a stable protective film on metal surfaces, significantly reducing corrosion rates of carbon steel, copper, and other alloys in water systems.
3. Good Chemical Stability:​ Maintains its effectiveness under high temperatures and over a wide pH range, ensuring reliable performance in demanding conditions.
4. Synergistic Effects:​ Compatible and often used in combination with other water treatment chemicals like polymeric dispersants (e.g., HPMA, PAA) and corrosion inhibitors (e.g., HEDP, PBTCA) for enhanced treatment programs.
5. "Low-Phosphorus" Alternative:​ Considered more environmentally favorable compared to traditional inorganic phosphates due to its higher stability and lower dosage requirement.

Typical Applications:

1. Industrial cooling water systems (open recirculating and once-through)
2. Boiler water treatment
3. Reverse Osmosis (RO) membrane anti-scalant
4. Oilfield water flooding and refinery systems
5. As a chelant in textile, metal cleaning, and papermaking processes.

Uses for Different ATMP Types

1. Standard Cooling Water Systems: ATMP Liquid is the best choice. It is ready to use and works perfectly with automatic dosing systems. It makes daily maintenance much easier.
2. Global Trade or Cold Storage: ATMP Powder is recommended. The high concentration reduces shipping costs. It does not freeze in cold weather and is easier to store for a long time.
3. Acid-Sensitive Systems or Oilfields: ATMP •5Na is the best option. It is neutral or slightly alkaline, so it does not hurt the equipment. It also works better against scale in oilfields.
