PBTC 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. PBTC has good chelating ability for heavy metals.
2. PBTC is a weaker complexing agent for metals than EDTA. Hence, it eliminates the remobilization of heavy metals from sediments.
3. PBTC also has excellent tolerance towards chlorine and hypo-chlorites in the presence of bromine where most of the other phosphonates degrade extremely fast.
4. Its 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.
Applications:
• Industrial cooling water treatment.
• Industrial and institutional cleaners (I & I formulations)
• Disinfectants
• Liquid dishwashing and detergents
• Metal surface treatment
• Sequestering agent in textile auxiliaries
• Hypochlorite stabilization
