Phosphino-Carboxylic Acid(PCA)
CAS No. 71050-62-9
Properties:
Through the introduction of phosphonic group into carboxylic group, POCA has good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale. POCA has advantages in wide range of water quality, chemical stability, strong chlorine tolerance, etc. POCA can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
