Phosphonobutantricarboxylic acid is a very effective scale inhibitor used in various industrial applications.
Due to its higher performance properties it is a very cost effective inhibitor compared to standard Phosphonates such as HEDP/ATMP.
This is mainly due to superior stability to chlorine, bleach and bromine.
In cooling water PBTC performs well at high PH or temperatures.
Phosphonobutantricarboxylic acid further shows high effectiveness in high alkaline solutions such as industrial cleaners.

Phosphonobutantricarboxylic acid is a low phosphorus chemical containing organophosphonate, which is known to be a highly effective threshold scale inhibitor.
In other words, at very low (ppm level) levels, sub-stoichiometric concentrations calculated on hardness of water, it acts as excellent scale inhibitor for carbonates, sulfates and phosphates.

1. Phosphonobutantricarboxylic acid has good chelating ability for heavy metals.
2. Phosphonobutantricarboxylic acid is a weaker complexing agent for metals than EDTA. Hence, it eliminates the remobilization of heavy metals from sediments.
3. Phosphonobutantricarboxylic acid also has excellent tolerance towards chlorine and hypo-chlorites in the presence of bromine where most of the other phosphonates degrade extremely fast.
4. Phosphonobutantricarboxylic acids excellent thermal stability at various pH ranges, enables it to remain effective even at high pH levels and temperatures.
Additionally, it has the dispersion property. Its anions get adsorbed by inorganic particles in the water giving it the dispersion ability.
Lastly, it is a good corrosion inhibitor for carbon steel. Hence, it is part of all organic water treatment programs.
