CAS No. 71050-62-9
TH-164 Phosphino-Carboxylic Acid（PCA）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.
TH-164 PCA has advantages in thermal stability and strong chlorine tolerance.
TH-164 PCA can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
TH-164 PCA has better performance than acrylic products in paper making mill, ceramic industry and etc.. It can also be used to disperse scales in boilers.
