Phosphino Carboxylic Acid(PCA)
Phosphino Carboxylic Acid (PCA) is an organic chemical compound that combines the characteristics of phosphonates and polyacrylates. It is used as a special equilibrium of water treatment chemicals, providing excellent thermal and chlorine stability. PCA has good dispersion properties for calcium carbonate and calcium phosphate scale in circulating cool water systems, as well as superior boiler water sludge dispersal compared to polyacrylates, polymethacrylates and sulfonated compounds. Additionally, it has good scale inhibition for barium sulfate, strontium sulfate and silica scale. PCA is an effective choice for a wide range of water treatment applications.
CAS No. 71050-62-9
Phosphino Carboxylic Acid Properties:
PCA is a perfect solution for scale and corrosion control in circulating cool water systems and oilfield refill water systems. Its properties, such as the introduction of the phosphonic group into the carboxylic group, make it a great option for scale inhibition of barium sulfate, strontium sulfate, and silica scale. PCA is also well-known for its good dispersion property in terms of calcium carbonate and calcium phosphate, making it usable in a wide range of water quality. In addition to all these benefits, PCA stands out due to its chemical stability and strong chlorine tolerance.
