PBTC is a high-performance Technical Grade scale and corrosion inhibitor specifically engineered for high-alkalinity and high-hardness water systems. It exhibits exceptional stability in the presence of oxidizing biocides like chlorine and bromine.

The molecule functions as a potent sequestering agent, outperforming standard phosphonates in controlling calcium carbonate precipitation. It is characterized by its high thermal stability, making it suitable for high-temperature industrial cooling circuits and boiler systems.

This acidic liquid is widely used as a stabilizer for zinc salts and a chelating agent in specialty detergent formulations. It maintains its anti-scaling efficiency even under extreme pH conditions exceeding 14, ensuring long-term system protection.

Phosphonobutane Tricarboxylic Acid (PBTC)
  • Cooling Water Treatment: Inhibits calcium carbonate and phosphate scale in industrial circulating systems.
  • Industrial Detergents: Acts as a chelating agent in metal cleaners and heavy-duty alkaline cleaning solutions.
  • Oilfield Operations: Prevents scale formation in reinjection water and processing equipment during extraction.

Classified as Corrosive to Metals (Category 1) and causes Serious Eye Damage (Category 1). Always handle using Chemical Resistant Gloves, Safety Goggles, and Protective Coveralls to prevent skin contact or inhalation.
