Phosphono Carboxylic Acid Copolymer (PCA)
Properties:
By introducing a phosphonic group into a carboxylic group, Phosphono carboxylic acid has good dispersion properties for the scale of calcium carbonate and calcium phosphate in the circulating cool water system. In addition, it has good scale inhibition for barium sulfate, strontium sulfate, and silica scale.
Phosphono carboxylic acid has advantages in water quality, chemical stability, strong chlorine tolerance, etc. In addition, phosphono carboxylic acid can be a scale and corrosion inhibitor in circulating cool water and oilfield refill water systems.
